What Does This Mean for Enterprises?
- All existing certified enterprises need to submit test reports and conformity declarations for the new standard before the deadline.
- Enterprises that fail to complete the standard switch before the deadline will face certificate cancellation or model deletion.
- Newly applying enterprises need to explicitly commit to implementing the new standard before the deadline.
Battery Manufacturers Also Need to Pay Attention?
As a key component of UPS, battery performance directly affects the safety of the entire machine. Battery manufacturers need to cooperate with UPS enterprises to ensure that their products meet the relevant test requirements of the new standard.
