Hi in a previous video number 996 to be precise, which I'll link it down below and up there somewhere. and at the end of this video, if you haven't seen it. I Talked about the seee mark and various other marks like this garbage bin in the Rose compliance mark and other sort of certification marks that were on products. So if you haven't seen that, link it in down below.

but I Pray in that video. I actually promised to look at some more logos that we you see on the back of products. So you often find these sorts of logos on anything that pretty much involves safety like these power plug packs, for example. Look, they're absolutely filled with logos.

and heck, and even my own modi meter has one of these type approval logos on it. ETL What do all these things means And we're going to specifically take a look at the UL one. But not only that, there's other ones like this. CCC What does that mean? Tuv The ETL Intertek mark I just showed on the multimeter number.

What's that? There's a whole bunch of what are called type-approval mark. so let's take a look at them. The UL logo or the Underwriters Laboratory logo that you'll find on products. What does this actually mean? Underwriters Laboratory or UL are a certifying an American certifying agency that test and certify that products meet a particular standard and Ul.

There's various Ul standards which they even might write themselves or they get from other parties and modify the standards and souls. And there's a whole bunch of these and they'll link these in down below if you want to actually go into their standards catalog. and this is standard for practically everything: Fire Tests of window assemblies, tin clad fire doors I don't know, there's 62 pages Mefford for the tests, the spread of fire and oh geez, we're still just on fire anyway. The ones where specifically can more concerned about on this channel, of course is electrical safety and of course plug packs.

Things like multimeters like this. So safety is a really big thing in products and there may be a legal requirement in a certain country to have something type approved and actually have it. Either Ul or some of the other logos we're looked at have things type approved before they're allowed for sale in the country, but that's not always the case. For example, you can import and sell a $2 multimeter, which this one is not.

You can import and sell a multimeter no problems whatsoever, and it has no Ul logo on it at all. It does. It may or may not meet the safety requirements, but what having this Ul logo on the back of a product means is that it has been independently third-party tested by the underwriters laboratory and certified to meet whatever particular standard that you're testing against for sale in whichever country, and then if it meets that standard, they'll publish a report which we'll take a look at and then the manufacturer gets to put on whichever logo you've got here and you'll see all these different types of logos you might see one with. it's got to see at a Us next to it.

That implies that it's a standard applies to both Canada and the US, but there's various other like. There's just no end to the variations of this logo. So, but generally Ul just means Underwriters Laboratory third-party certified and tested safety. And yes, there could actually be fake products that have the UL logo on it that were not independently certified and tested.

So any reputable manufacturer will, actually, upon request, will provide the UL test certificate often on their website or something like that. You can download it the full or partial our certificate from the UL certifying that that company has actually had this test done. But there are fake ripoff products out there that simply slept these logos on and well, you know that's almost impossible to stop, but you know that's what happens when you buy a $2.00 charger from China. But the good news is is that these are type approval agencies will actually go after companies who are misrepresent and their logo or sell fake or imported products like that that contained their logo.

They're very strict on that. So yeah, you don't want to give me going slapping on a UL logo on a product if you haven't actually had it tested by them. I'll kick your ass because this is the Eevblog you may be interested in. Multimeter are Ul certification for example.

Well, this is the UL 60, 101, Oh standard which relates to the Cat input ratings for example of multimeters and the electrical safety of multimeters like this and this actually comes from the IEC 61, oh I know standard and Ul might have either slightly modified or just copied that directly from another particular standard and you might have actually seen this weird one which looks like a back-to-front R and a u. This is actually to do with Underwriters Laboratory as well, and you might see these on there. It is on a hard drive there, for example, and generally you won't find these on the back of a finished consumer product and this is what's called a recognized component mark that goes onto things like this hard drive which is actually a computer component which goes inside a finished computer which then might have the UL logo on it for example. and that just certifies that that particular component inside the system meets a particular standard by the underwriters laboratory.

They just use a different mark for that, so you might find those on a fool like it's like subsection component like this hard drive or you might find it on a PCB for example. And once again, the C and the US mark there designates are Canada and all the US so that just signifies that the manufacturer has paid to have that particular component or subsection tested for some sort of standard or certification by the underwriters laboratory. In the case of, say, an internal power supply, just the blade. you know, the power supply PCB inside a computer for example, that might have this are you mark on it.

Which means that they actually had that just that power supply subsection independently tested. And of course, there'd be advantages to doing that. If all your individual are critical, say safety sub components are all individually certified, then it makes the top all Ul certification to put that Ul logo on the back much easier when it comes to certification time. So although the UL mark is hugely encompassing, you can just think of it as a third-party independent, safe safety certification standard.

Take for example, the 6100 101. Here, let's look at all the different they're the different standards available for the set. There's 17 different standards under the 60 101. Oh Things like that, that's just one subset of one standard.

Crazy. But it's quite often that you're were see on the final product, not just the UL logo, but underneath You might find the particular standard that it actually meets. But that's not strictly a requirement. You could have that somewhere else in now.

your documentation, but you will isn't the only game in town. They're just one independent company who happened to do of these safety certification things. Take for example, the Eevblog Multimeter. There it is.

It's got this ETL on it What does that mean? Well, that is just yet another reputable third-party independent test organization that certifies and tests in this case, do exactly the same. So IEC 61, Oh 100 standard as the UL do, but it's just another company doing it. You might use them because they might be cheaper, or because they might have you know, like a better service. They might have a faster turnaround time.

It doesn't matter, they're both are reputable and the ETL logo in this particular case means it's been not certified to exactly the same standard, but certified by Inter Tech which is company. And look at, these are once again, all the different consumer food and health, energy, commodities, chemicals, construction engineering. They'll certify almost anything just like you will. It's exactly the same thing.

You generally wouldn't have your product both Ul and ETL tested because in the case of this multimeter, it's got the same C and Us next to it Canada and the US so you wouldn't really bother getting at both Ul tested and Intertek ETL tested for the two same countries. There's just really no point. So just like the UL logo, the ETL Intertek logo, it's just yet another way to show to your customer that your product has been independently safety and certified tested. And as with the UL and Intertek, you can actually search their databases to actually see if the product and that company has legitimately had it tested by them.

When you pay your money to have this tested and certified by Ul or ETL or some other type approval agency, you get a pretty comprehensive report. This is my one for example or one of them for the 121 GW multimeter and they take all these photos. Very typical. sort of like certification.

You will type our testing photos, they're making out all the critical safety components and how they're all individually tested. And here's the interesting thing. see how it's got CR u RS We talked about that before. that's that a component conformity mark.

so that that's why mark of conformity for each into the individual components. So the fuse used in there. they've got the type bottle number of the fuse for example, and the model number of various site you know, the keypads, the plastic enclosures, the LCD windows they've all been. All these components have been independently certified and tested, so that makes the job of then giving an overall Ul or ETL acceptance for the product much easier because these components you can prove that they've all been independently are certified in their own right.

and then they'll document where you can stick it sticky. a logo. That is there. It is.

the Canadian and US are ETL Intertek logo. That's the certification aren't number down there. you can look that up and then they'll actually specify under. There you go, it was I you will.

even though it's a Ul standard thing that they were testing against, its tested by ETL It's got nothing to do with Ul, but it just happens to use their version of the UL standard there. And the CSA you pay your money and they don't just rubber-stamp things in. In the case of this particular multimeter, they came back the test house. They won't just fail you.

typically the come back and say hey, look, we look, it's even not passing this particular test or whatever. Well, we think it's not gonna pass this test based on our experience and you might want to modify this and hey, let's start again. So often there's a bit of back-and-forth there that just allows you to fix things are properly before they just you know you pay your ten thousand dollars or whatever and they just go. sorry it failed, Do it again.

And then there's page six of 85 and it just Everett's past or not applicable. All these like separate independent tests that they actually do this thing. This is why getting a product a Ul or ETL type approval testing can take months. It's just a very long process.

Not only is there a long queue of companies waiting to have their products tested, but just to test the one product takes a long time. But getting back to UL logos it doesn't just end with like the sea and US there are marks for Europe as well. the D might be safety mark, the En Ec mark, then ul it with EU below it and there's a new Ul certified logo. They're trying to sort of, you know, transition over to sort of a new look logo and things like that.

You can get Canadian, US and EU listed under there and this new one actually has the the qualification number on the thing. and then there's a Ul GS mark which we'll have to get into and then this marks for Asia as well. Look at this s Ni UL ID and there's the PRC you made it. might have seen that on some more power supplies.

that's a Japanese specific one s mark as well and like it just goes on there. No, no, no, we're not done yet. Latin America Oh Norm there's that nom nom nom nom nom. but you will.

and Intertek They aren't the only ones in town. Of course there's others like our Tuv. For example. There we go these Tuv markings.

We'll take a look at that Csa that's the Canadian standards Association and they will do my independent certification to the same standards yet again. and you can put their marking on. and it's got the ID number and stuff like that. So if we actually take a look at Tuv they're actually a German company so you know if you want to get it certified in Europe.

That's why you notice that the UL one, I had Canadian and US and EU. Well, if you want a specific German one, the Tuv is the way to go. For example, once again, they do all sorts of lab equipment, machinery, robotics, all sorts of anything, just literally anything. and very often.

the T UV mark here is next to the GS so they call it like GS /r T UV for Germany and EU market and the CSA the Canadian our standards association that CSA mark. Once again, they'll do all your product testing and verifications and that's why you end up with a whole bunch of these markings on the back of your product cuz you know reputable companies. In this case, this is a Dell for example, they get these products I think this is a monitor and they get them certified and they want to sell them in all these different countries they've got have made various electrical and Safety and approval standards and CES all. it's kind of the separate thing.

but anyway, safety and certification standards in all these different countries. So they stamp stamp, stamp stamp. but you know they don't just rubber stamp these things. They would have actually sent this particular monitor away to every single one of these groups and it probably took a couple of months there too.

and at each one to get tested. and I'm sure if you really wanted to audit Dell you know you're a big fight. You can ask for the certification, the testing documents for this particular monitor if you wanted to and here's where it lives. It gets a bit tricky in terms of our definitions.

We've been looking at type approvals as a Ul and your Tuv and all those sort of ones technically called type approvals, but they're essentially certifications against a standard. and there's other certification marks like so the CCC one here with the registration number down below. That's actually that stands for the China compulsory certificate and that's a like an In Chinese certification standard. So this monitor has been registered with that Chinese Standards Testing Authority and if you want to sell your product in Argentina, you need one of these Argentine Republic or you may or may not depending on the local country standards.

Um, this I Ram mark here and we'll take a look at that. There you go, The Institute I won't even try and pronounce that anyway. Another certification type approval Authority And if you want this nomnomnom mark down in the corner here and sell your product in Mexico and make it all official and certified type approved. Our Nam is the Norma official Mexicana, so it's the local Mexican type approval standard and our Intertek will do this Tuv.

We'll do this and some other ones are just a certifications marks like the C tick here which actually is an older Australian standard. They don't have that anymore. It's now scored in our Cm or a regulatory compliance mark and that's really not to do with in this particular case, any of the safety certifications for the multimeter, for example, it's basically just our EMC compliance. so basically are the same as the FCC.

That's generally, while they'll bunch them together like this, they'll have the C II which I've done the video on the FCC and the regulatory compliance mark, so that's different. Those sort of certifications are different to the type approval safety standards that we're looking at here with the UL and etc. And there's just no shortage of these sort of marks on all sorts of different products. And like, you know, you can go through all these until the cows come home.

Suffice it to say that they're either a certification mark for our EMC and EMI our compliance, or they're a type approval regulatory safety mark to ensure that the product is independently third-party tested. So there you go. I Hope you found that interesting. I'll put some links down below to all this sort of stuff.

If you're designing and selling a product that has any sort of safety requirements at all I mean you're probably almost certainly going to have to meet our basic compliance in terms of EMC. So see e FCC and the C Tech and regulatory Compliance mark for sale in various countries and things like that. But then whether or not your product has to be type approved to some sort of safety 10th standard depends on what type of our product to This and all of this testing can cost you know, tens of thousands of dollars and can take months, especially if you fail. You have to Reese pin your boards Reese pin your product do whatever.

You know it can be an iterative type of process. so generally you want to talk to your test house. You want to find a test house. They can do as many of these regulatory compliance marker tests as possible and often they'll do okay.

You just tell them I want to sell it in all these countries and they'll advise you on which marks you need, which standards and type approvals, and all that sort of stuff you need and they'll generally work with you to finish off the product and get it all approved. But yeah, takes a lot of time and money and you have to schedule that into the development of something like this. Moldy mean you have to go. Well, Look, it's gonna take.

we can't ship this. It's gonna take two months to get that stamp on the back of it. That's just. do you know how long it takes? You can't ship it before that.

So there you go I hope you found that interesting. If you did, please give it a big thumbs up because that always helps a lot. And subscribe over here. know there somewhere and that little bell icon theme.

Click on that so you get notified. And also there's a new our community tab used to be the discussion tab on my channel and I'll link that in down below and you can get updates and things like that, especially on your mobile phone. I'll post like if I'm going live on my second channel or something like that I did that the other day and I posted that on there so everyone got notified of all that sort of jazz. anyway.

hope you liked it. Catch you next time you.
