A quality manager once told me she doesn't trust suppliers who boast about their certifications. She trusts the ones who invite her to watch a test. "Certificates can be bought," she said. "A chamber running in front of you cannot." She had learned this lesson after a supplier presented an impressive ISO certificate, then failed a simple salt spray test in her own lab. The certificate was genuine—but it was for a different product line, tested years ago. The supplier had assumed no one would check. She checked. Now she insists on witnessing tests for every new supplier. "I don't want to see your paperwork," she tells them. "I want to see your samples in my chamber." The suppliers who agree are the ones she keeps. The ones who hesitate are the ones she rejects. At BOTO GROUP, we build salt spray chambers for manufacturers who understand that the most convincing certificate is the one you watch being earned.
