I did a lot of research on the new CQC requirements when I first found out
about them in early 2012 so some of the information, like drop dead date,
below may have changed since then but here is a short version of what I learned.
I can only speak Audio/ Video Products but this requirement was published in
the 2011 version of GB8898 (IEC60065) December 30th 2011. The transition dates
for implementation were published by CQC on April 11th 2012.
The drop dead date for meeting the new requirements and updating your CCC Mark
certificates to the 2011 version of GB8898 was February 1, 2014 after which the
certificate would be cancelled by CQC.
The short answer is there are two new requirements to consider
1. Altitude: this requires meeting increased creepage requirements based
on a max altitude of 5000m. Per IEC60664-1:2007 the clearance spacings increase
by 1.48X the spacing for product for install below 2000M. As a result creepage
distances will also increase as creepage cannot be less than clearance.
2. Tropical Environment: In addition to testing the product for an ambient
temperature of 45C the product must meet reduced limits for Touch Current and
for Hazardous Live parts.
If you cannot meet the new Altitude and /or Tropical Environment you can mark
your product and put information in the user instructions.
Here is what I learned about the marking requirements. I can’t include the
symbols due to list rules but the UL fact sheet Chuck posted the link for shows
the symbols.
As an alternative to meeting the increased spacing requirements you can declare
the products are not meant for installation at altitudes above 2000m and add
the following symbol and verbiage, in Chinese, to the product label.
(Symbol for Altitude placed here)
“Only suitable for use at areas with altitude less than 2000m”
“仅适用于2000m以下地区安全使用”
(Chinese translation)
If only the symbol is used on the product label, due to size constraints, it
shall be explained in the user manual. The safety warning sentence shall use
the language acceptable to the country where the apparatus is intended to be
sold (simplified Chinese is acceptable).
For low voltage product with an external wall/floorwart power supply only the
power supply will need be marked with the symbol or verbiage if noncompliant.
The low voltage product is exempt from the marking requirement.
2. Tropical conditions
Products must now comply for use in Tropical conditions and ambient
temperatures above 45°C. If the product is evaluated for compliance for those
conditions and is found non-compliant the product must have the following
symbol and verbiage on the label.
(Symbol for Tropical
conditions placed here)
“Only suitable for use at non-tropic climate areas”
“仅适用于非热带气候条件下安全使用”
(Chinese translation)
If only the symbol is used on the product label, due to size constraints, it
shall be explained in the user manual. The safety warning sentence shall use
the language acceptable to the country where the apparatus is intended to be
sold (simplified Chinese is acceptable).
For a system comprised of an external power supply and low voltage product both
may need the markings if they don’t comply with all of the heating, reduced
touch current and accessible hazardous voltage limits.
So you do have the choice of complying with the new requirements or marking
your product and including information in the user’s manual.
Hope this helps and please feel free to correct anything you feel is not valid
in my post.

Are these symbols and text required for all EEE shipped to China or only ITE?
This is the first I’ve heard of this.

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.
Regards,
Mike

Hello all,
I am being asked to add two symbols to my product silkscreen for CCC Approvals.
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.
Scott
