We are bringing a wearable product to the market that is powered by a 3.7V LiPo battery. The product will be sold initially only in the EU and US markets. We are currently in the process of performing the necessary tests and assessments with a test lab to certify that the product complies with the necessary Radio, EMC and Safety standards.
As part of this process, I know that certain tests are required for the LiPo battery. The battery supplier has provided the following reports for the battery:
- UN38.3 report
- 1.2M Drop Test report
- Report for safe transport of goods
- MSDS report
- IEC 62133-2: 2017 report
Now the problem:
The test lab says they can accept the IEC 62133 report for the safety requirements in the EU. However, they insist that the above are not sufficient for the US and more testing is needed according to the UL 1642 standard (which also they cannot perform, as they are not accredited to do so, i.e. we need to find another lab to perform that testing).
The battery supplier however is based in the US and sells the same LiPo batteries directly to customers there, without experiencing any problems.
Who is at wrong here? Is the test lab exaggerating a bit here about the need for UL 1642 or is the battery supplier selling products that have not actually passed the safety requirements for the US?
One thing to point out for clarity, that the battery supplier sells standalone batteries, while we are certifying (and intend to sell) the product as a whole (not just the batteries).
