I work for a small sized company in construction industry. We have received a checklist from a new customer, requiring us to answer if we comply with specific standards, such as "ASTM A475 Standard Specification for Zinc-Coated Steel Wire Strand". My question is if we can answer yes, since we only specify this in our purchase order for our provider (meet ASTM A475 requirements), we don´t make any mechanical tests for strands.
