En en is a European safety mark

ENEC (European Norms Electrical Certification) is a certification program of the CENELEC (European Organisation for Electrotechnical Standardization) that is a common European standard for specific and European-compliant products such as lighting, components, and office & data equipment.

The ENEC mark is a common mark for European safety certification, which is adopted by European manufacturers on the basis of tests carried out on the basis of harmonized European safety standards.

At the 98cca meeting held in Yugoslavia in March 2000, it was unanimously agreed that the "ENEC" mark, which was previously only allowed to be used by European manufacturers, will be open to all manufacturers around the world.

Initially, certification was only for IT (information) equipment (EN60950), but today the scope of the "ENEC" mark includes:

Information equipment (EN60950).

Transformer (EN60742, EN61558).

Lighting (EN60598) and related documents (EN60920, EN60440).

Electrical switch (EN61058).

European Standard Electrical Appliance Certification" The number that appears to the right of the ENEC mark is a mark that identifies the different member states of the CCAThere are now 21 Member States and 23 Accreditation Bodies.

The certification body's mark can also be added if the manufacturer wishes. ENEC certifies to consumers and authorities that the product has been certified by a highly credible third-party certification body. In short, the logo requires:

Tested and certified by the certification bodies of the ENEC member states. Such as: nemko, semko, etc.

Manufacturers' product management must comply with ISO9002 or its equivalent.

According to the harmonization inspection procedure, the initial and minimum annual production will be subject to inspection by the issuing authority.

Certified products are selectively retested every other year.

EN is the symbol of the European Union, and EN is the symbol of NATO in Europe.

EN (European Standard): The adoption of this EN standard will give legal status to the relevant national standard of a member state, or revoke the relevant standard of an opposing country, according to the common obligations of the participating countries.

You this project. It's not much smaller than the Three Gorges, so much, not to mention one person, it's not necessarily a lead manuscript pile, you have to be targeted, what products, what standard type is closed, it's not too much, and you can't finish it in a few days.

The same is the first floor.

Your de-tracking question is too wide.

At the very least, it is necessary to explain the products of the Ranran.

Or you can find it yourself.

I'm eager to help others, but I can't meet these standards.

If your product is not an unlimited product (Bluetooth, WiFi), then the product is applicable to the EMC corresponding standard under the RTTE directive (EMC test is not understood) and safety standard (this has to be selected according to your product selection standard).

EN 60950-1 is the Information Technology Equipment Safety Part 1: General Requirements (also harmonized under the RTTE Directive, as well as the harmonized standard under the LVD Directive).

rtte（radio and telecommunications terminal equipment）

lvd（low voltage directive)

It's the standard of Europe and the United States, for example, the standard at the beginning of GB refers to China

What VDE CE and so on, the standards and ** of each country are different.

The previous standard is the European Union's standard "Low Voltage Surge Protection Devices". Part 11: Surge protection devices connected to low-voltage distribution systems, the latter standard is the national standard in Germany.

Medium and high voltage porcelain capacitor, is an electronic component EN60384-14 is the Xiangshi standard of capacitance, 05-10 should be the date, it should also be marked with capacity such as: 222 is 2200pf, pf is the unit of capacitance capacity, just like the unit of voltage v (volts.

250 is the rated AC voltage of 250V, I am engaged in home appliance maintenance, I hope to help you.

EN60384-14 is the ANWU standard for all capacitors, and 05-10 should be the release date, which is the environmental test of the report capacitor, the safety test, and the electric cavity orange parameter test.

This, our company has done Nashanyin, and we are happy to send you information.

Product certification testing standards:

LVD: EN60065, UL60065, IEC60065EMC: EN55013, EN55020, EN61000-3-2, EN61000-3-3

We are a safety certification company, and we can help you do safety certification.

The on-road test is not accurate and is not real data, because there is the equivalent resistance of the circuit, it is accurate to remove the measurement or take it apart.

As for whether it can be removed, it depends on its role in the circuit.

In general, since this capacitor is used, it must have its effect, and of course it should not be removed.
