Scope note: The certificate states that it applies to the tested sample and does not assess the whole production. It does not name SJ-15H, SJ-35H, or the -40C/-55C/-60C configuration suffixes. It covers the referenced LVD test only and does not by itself replace an order-specific EU Declaration of Conformity, technical file, EMC/RoHS evidence, or other documents required for a destination.
