The national difference for China regarding tropical conditions is very similar to national differences for Singapore, Mexico and a few other tropical countries. It is relatively simple to meet this requirement with temperature/humidity preconditioning before the electric strength tests. As such, it isn’t too difficult to design products to meet the tropical condition requirements and thereby eliminate the need to apply the “no tropical conditions” marking.
The altitude marking is more of a challenge. The Chinese national difference requires equipment to be designed for altitudes of 5000 meters minimum before this marking can be removed. This requires a significant change to spacings in power supplies. The way the regulation is written, unless the product is designed for use at 5000 meters, it must be marked for use at less than 2000 meters. There is no option for marking at altitudes between the two. That being said, the altitude marking is not required for SELV powered products where the spacings do not apply. For example, a laptop with an external supply would have the altitude marking on the power supply but not the laptop.

This is the first I’ve heard of this. The Other Brian From: Mike Cantwell [mailto:[email protected]] Sent: Tuesday, September 30, 2014 8:10 PM To: [email protected]<mailto:[email protected]> Subject: Re: [PSES] Symbols for CCC Approval Hi Scott, This requirement comes from the National Differences published in the CB Bulletin. If the product is ITE, then clause 1.7.2.1 was modified. It is acceptable to provide the Chinese translation of the statements below as well as to use the icons. I can provide the translation if you email me directly. China doesn’t provide nice graphics for the symbol, you have to pull them right out of the CB report. Add requirements of warning for equipment intended to be used at altitude not exceeding 2000m or at non-tropical climate regions: For equipment intended to be used at altitude not exceeding 2000m, a warning label containing the following or a similar appropriate wording, or a symbol as in annex DD shall fixed to the equipment at readily visible place. "Only used at altitude not exceeding 2000m." <mountain icon> For equipment intended to be used in not-tropical climate regions, a warning label containing the following or a similar appropriate wording, or a symbol as in annex DD shall fixed to the equipment at readily visible place. "Only used in not-tropical climate regions.” <humidity icon> If only the symbol used, the explanation of the symbol shall be contained in the instruction manual. The above statements shall be given in a language acceptable to the regions where the apparatus is intended to be used.

One symbol is a not circle with waves at the bottom (water) and curled lines above (moisture I guess). This is to signify not for use in tropical regions. The second symbol is a circle with mountains and <=2000m inside it. This signifies use only below 2,000 meters in altitude. Can anyone tell me where these two symbols come from (standards reference) and where one can get vector artwork for same? Thank you in advance for any help provided.
