What we don't know about the factory inspection standard of touch switch? Let me introduce you today.

 

RoHS directive refers to the "directive on the restriction of the use of hazardous substances in electronic and electrical equipment". The directive prohibits the introduction of Flame Retardants Containing Lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in the EU market.

 

All APEM switches are RoHS compliant.

 

What is ip69k protection level?

 

The purpose of this test is to simulate a pressurized clean environment on a clean platform. The test equipment shall be set up according to DIN 40050-9 standard of Germany, and the rating system of IEC 60529 standard shall be used to evaluate whether the tested equipment has reached ip69k high temperature and high pressure washing. In addition to dust-proof capability (ip6x), the tested equipment must also be able to withstand high pressure and steam cleaning. In the test, a nozzle that can spray water with a temperature of 80 ° C, a pressure of 8-10mpa and a flow rate of 14-16l / min will be used to wash the tested equipment at 10-15cm away from the tested equipment at 0 °, 30 °, 60 ° and 90 ° for 30 seconds. During the test, the tested equipment on the turntable will rotate at a speed of 12 seconds (5 RPM).

 

What is IP rating?

 

The IP rating code (International Protection rating, or entry protection rating) is composed of the letter IP and two digits after it. Sometimes, an optional letter may be added after it. According to the definition of International Standard IEC 60529, IP rating is used to grade and evaluate the ability of electronic products to prevent solid objects (including hands, fingers and other human parts), dust, accidental contact and water entry. Two characteristic numbers indicate the relevant protection level, and the specific test conditions are shown in the table below. If you don't pay attention to the protection of an item, you can use x instead of the corresponding characteristic number.

 

What is ul94-v0? Does the waterproof touch switch of G-switch meet the standard of fire rating?

 

UL 94 is a plastic flammability standard issued by Underwriters Laboratories in the United States.

 

This standard defines and classifies plastic materials according to different burning direction and thickness. From the lowest level (worst fire resistance) to the highest level (best fire resistance), the classification is as follows:

 

HB: slow burning in horizontal direction; burning rate on 3mm thick sample < 76 mm / min.

 

V2: it will be extinguished within 30 seconds after burning in the vertical direction; the burning particles are allowed to drip.

 

V1: it will be extinguished within 30 seconds after burning in the vertical direction; dripping is not allowed.

 

V0: it will be extinguished within 10 seconds after burning in the vertical direction; dripping is not allowed.

 

5vb: it will be extinguished within 60 seconds after burning in the vertical direction; no dripping is allowed; the sheet sample will form a concave hole.

 

5VA: it will be extinguished within 60 seconds after burning in the vertical direction; no dripping is allowed; the sheet sample will not form a concave hole.

 

The selection of tap switch must pay attention to these standards and determine the details of tap switch.
