Principles of authentication PSC PSE Q&A Radio Law
この記事は約 19 分で読めます。 7 Views

Hello. It is a hori of the manager.

When I receive many inquiries about certification, is it okay to do not need to authenticate such as PSE or radio law because the Chinese factory seems to have obtained CE (European certification)? There is a content that.

To conclude earlier, CE certification is only a European certification, so acquiring it does not exempt Japan's compulsory authentication (PSE, Radio Law, etc.). However, I think that it will be one to prove the height of the quality of the product.

It is a label content that I do not usually care about, but when I try to handle electrical appliances and electrical appliances as a business operator, I am quite worried.

This time, I would like to tell you mainly whether the display is required or not with the content that there were many inquiries.

Review of general PSE display contents

Because it is an adapter used overseas, there are many displays that are not directly related to PSE (Japan)

This image is the charging adapter PSE display part of the laptop I am using. I would like to give you an example of what I want to tell you just right.

I would like to tell you based on the contents of this place.

In addition, the contents that must be posted at a minimum for PSE display are as follows. In addition to this, what you need to post will change depending on the product.

Let's talk about the PSE display of the charging adapter.

Name of registered inspection body

If you are a general user, it is a story that does not matter at all, but if you are a business operator and are in a position to sell PSE products, it is a place that you should be careful and check.

In terms of the image adapter, TÜV RT is the name of the registered inspection authority.

This time, the charging adapter PSE is used as an example, but for specific electrical appliances (diamond PSE), it is necessary to display the name or abbreviation of the registered inspection body that recognized it, the logo, etc.

It should be noted that the Ministry of Economy, Trade and Industry does not give instructions on which registered and registered inspection bodies should be displayed. The business operator must obtain the logo data of the inspection organization by itself and display it themselves.

Some of them have already been displayed by the Chinese factory, but operators are obliged to confirm for themselves whether the content is really correct.

The worst pattern is, for example, displaying the logo of the B inspection authority while holding the certificate of the A inspection authority. This may not be a major problem, but if the Minister of Economy, Trade and Industry points out it, it must be improved, and it is most important not to make unnecessary mistakes because it depends on the judgment of the Ministry of Economy, Trade and Industry whether there is a blame.

The list of pse registered inspection bodies is gathered here, so please refer to it. In addition, the display of the registered inspection organization is only specific electrical appliances and supplies, and it is not required except for specified electrical appliances and supplies.

50-60Hz

This means that the frequency of "alternating current" electricity taken from an outlet corresponds to two, "50Hz" and "60Hz".

If you are a little familiar with electricity, you may know that in Japan today, the east side uses electricity of "50 Hz" and "60Hz" electricity on the west side, bordering Fujigawa in Shizuoka Prefecture and Itoigawa in Niigata Prefecture.

The historical background that has become this is different from the purpose of this page, so I will not discount it, but if you are worried, please refer to the link below.

If a 50Hz product is used in western Japan, it may cause a malfunction. The opposite is true, and the same is true when a 60Hz product is used in eastern Japan. However, I don't know if there really is such a thing in modern products, but in theory it will be.

It is very rare to be divided into two frequencies in a country, and there are 50-60 Hz that can be used only at 50Hz, only at 60Hz, or both for electrical appliances and materials. And we need to show which frequency we can use.

Basically, I think that most products are 50-60Hz, but you should check it.

Double girth double insulation display

The next is a double enclosure mark, which shows whether the product has a double isolation function. For explanations of double insulation, please refer to the following.

"Basic insulation" that provides basic protection against electric shock is further subjected to "auxiliary insulation" to protect in the event of a failure of the foundation insulation.

Even if the basic insulation fails for some reason, the hazardous voltage does not appear on the surface by auxiliary insulation, so that high safety can be maintained. Products with double insulating structure can be recognized by symbolic display of "double square mark". It is often used in electrical equipment used at construction sites, such as temporary lighting, electric screwdrivers, and sanders.

In electrical equipment defined as "a mechanism capable of grounding (grounding) such as an electrical device having a rated voltage of 150 V or more", if it is an electrical device having a double insulated structure, it is stipulated that grounding does not need to be applied.

Many electrical equipment used in environments that are easily contaminated with water, dust, etc., such as power tools used at construction sites, have a double insulating structure to enhance safety. On the other hand, when using electrical equipment that is not a double insulated structure, the connection of the ground wire is legally required.
Citation: Knowledge and technology of electrical equipment_Double insulation (reinforced insulation)

Since double insulation in electrical appliances is a basic item, I think that this display is necessary when handling it yourself. However, as mentioned in the quote, products that use ground wire are not required.

When confirming the labeling with the factory or inspection agency, please discuss it on the assumption that double insulation (display) is necessary. It is a very simple mark, but it is actually an important mark for the operator.

Mark limited to the use of domestic (power supply) only

Next is the residence mark, but this is only the use of the home (power supply), that is, the use outside is prohibited, more to say, it is not responsible for the accident when used outside.

The voltage in japanese homes (in buildings) is set at about 100v-110v, and it is designed that accidents cannot occur if used within that range, but the voltage used outdoors may not be constant, and in short, it means that there is a possibility of an accident if used in a strange voltage.

Obviously, this residence mark is rarely displayed for things that are only used indoors (which is basically not possible to use outdoors), but you'll see many marks on things that might be available both indoors and outdoors.

However, this is not a uniform decision, but a story with a product function, so please consult well with inspection organizations and production factories whether display is necessary.

The important thing is that you need to have this mark when importing, etc., and please check it yourself once.

Trash can marks stipulated for waste disposal

The trash can is marked with a × mark, but to conclude earlier, this is an unrelated mark in Japan. This is a display of the European Electrical and Electronic Waste Directive (Directive on Waste Electrical and Electronic Equipment: WEEE).

In Europe, the disposal method of electrical and electronic equipment is defined in detail, and this trash can mark indicates that it is a product that has cleared the regulations. If the product is also sold in Europe, there is no need to turn off the display, so it is a common story to sell it in Japan with the same display.

We also make many products for Europe at our chinese factories, and we sell them to Japan as they are. Japanese people who saw this display were once asked if they needed a recycling license.

Please refer to this page of JETRO for this mark. Overview of the JETRO_ Trade and Investment Consultation _WEEE (Electrical and Electronic Waste) Directive: EU

However, although it is a mark that is not directly related to Sales in Japan, if you look at these things, europe and other countries have firmly established methods for disposing of electronic devices, and it is certain that you can get a glimpse of the high level of environmental awareness.

Recycling mark for lithium-ion batteries (mobile batteries)

 

Finally, apart from the charging adapter at the beginning, I would like to explain a little about lithium-ion batteries that have recently become a hot topic.

Many of you may have seen this recycling mark in lithium-ion batteries (mobile batteries), etc.?

This mark is equipped with lithium-ion batteries, and instead of disposal as it is when disposed of, this mark encourages disposal (recycling) using local governments and collection companies.

As a matter of fact, at this stage in December 2020, the Ministry of Economy, Trade and Industry does not require the display of this recycling mark, but many companies are displaying this recycling mark.

In other words, it does not cost money to display itself, and some inspection institutions issue PSE inspection reports on the assumption that this mark is displayed.

Due to the rapid increase in fire accidents and the like, nearly two years have passed since the PSE legislation of mobile batteries has been decided, but the Ministry of Economy, Trade and Industry does not say anything about disposal (recycling) because it does not matter whether it is thought that there can be a fire accident in disposal, I do not know whether it does not say anything because it does not matter there, In any case, it is our view that it is better to only mark.

This was the explanation of the mark on PSE display. To be honest, we do not accept inquiries about displaying marks only, but if you are assuming certification, we will follow up in various ways, so please feel free to contact us if you are considering authentication.
