1. Partly to support their test labs and partly because they are not totally satisfied with the IEC standards that specify the tests. Particularly for lithium batteries, the technology is evolving far faster than the standards committees can change the standards (where/if necessary) and the standards can't accommodate new technology while it is undisclosed for commercial confidentiality. 2. It's not a matter of crossing borders and I doubt there are special EMC issues with lithium batteries. But the incidence of fires shows that either the basic technology or the manufacturing process, or both, is questionable. While that is so, the testing standards cannot be regarded as comprehensive.

From: Vincent Lee [mailto:[email protected]] Sent: Tuesday, January 3, 2017 8:35 AM To: [email protected] Subject: [PSES] In-Country Testing Hi all, Happy 2017, Having read about IECEE CB Scheme in which over 50 countries are participating members who agreed to mutually recognize each other CB test reports and certificates, may I know 1) What is the reasons or rationale between the requirements of In-Country Test (EMC, Safety Test) by some countries (e.g. PRC China, South Korea and Taiwan for EMC, India and Thailand for Li-ion Battery Safety Test)? 2) Will the product operating principle and behavior (e.g. Li-ion battery electro-chemistry) changed significant so as to cause EMC and safety issues when they cross the borders from one country to another ? Hope to hear from you soon. Thank you and Happy 2017 ahead.
