James Calder: Your company should continue requesting compliance information on obsolete parts. If the supplier or manufacturer has full composition data, they may be able to use this to provide updated compliance information. If the supplier or manufacturer is unable to evaluate composition information, ideally they would do their own testing or risk assessment to support a request from their customer (you). If they also refuse to do this, it’s up to you to perform risk assessment and/or testing. As always, ensure this process is carefully considered and documented. Compliance determination is especially important for obsolete parts, particularly if a part is crucial for existing or future products.
