--- About the use of ambient temperature modification. Chapter 1 of IEC 60669-1..2007 provides.

Suitable for use in ambient temperatures that normally do not exceed 25 ° C, but occasionally reach 35 ° C. Considering the geographical position of our country

Location, actual natural climate and environmental temperature distribution, the south of the Yangtze River is located in the sub-humid tropical zone and the annual average temperature

And the highest temperature is higher and the humidity is greater. Therefore, the operating environment temperature is changed to. "The indicator device that meets the requirements of this section is suitable for

It is used in an environment that usually does not exceed 35 degrees C and occasionally reaches 40 degrees C. "

--- For additional testing of thermoplastic materials or elastic materials, 10.1 of IEC 62094-1..2002 stipulates. "The shell or cover is a thermoplastic material

The indicator device of plastic or elastic material shall also be subjected to the following additional tests. The test is carried out at an ambient temperature of 35 ° C +/- 2 ° C.

OK, the switch should also be at this temperature. Taking into account the harsh conditions of the use of ambient temperature in China and the use of ambient temperature in Chapter 1

It is stipulated that "35 ° C +/- 2 ° C" be changed to "(40 +/- 2) ° C" correspondingly.

--- Regarding the moisture-proof test, 14.3 of IEC 62094-1..2002 stipulates. "Any temperature of

Convenient value t +/- 1K. Before putting the sample in the humidity chamber, make the sample reach t ~ t 4 degrees C. "Considering that parts of our country are wet

The tropical climate, and the electrical and electronic products in China all use (40 +/- 2) degrees C for humid heat test, so this section provides. "Test chamber

The temperature should be maintained at (40 +/- 2) degrees C. Allow the sample to reach this temperature before placing it in the humid chamber. "This provision is related to

GB/T 2423.3 "Environmental test Part 2. Test method Test Cab. Constant damp heat test" is consistent.

--- 12.2.1 According to the current situation of the product, change the conductor wiring capacity from "1mm2 ~ 2.5mm2" to "0.5mm2 ~

2.5mm2 ".

The following editorial changes have been made in this section.

--- According to the provisions of GB/T 1.1-2009, the "Scope" in Chapter 1 was supplemented by "this part of GB/T 38281 specifies household and

Technical requirements for the structure, electrical performance, and mechanical performance of indicator light devices of similar uses for fixed electrical installations. "

--- Removed notes containing requirements from other countries, such as 12.2.6, 13.23.2 notes.
