What is the difference between a certificate of compliance and a full certification (also known as chemical and physical certification)?
A certificate of compliance is a document that certifies the material to be in compliance with required specifications as mandated by the customer’s purchase order or specification. It will not include and chemical, physical, or mechanical testing results; however, the data, if required by the specification, is maintained by STP for future reference if necessary. The cost for this document is $10 per order. A full certification will include actual chemical, physical, and mechanical testing results for those properties required by the specification. The chemical results are provided by STP’s supplier while the physical and mechanical testing is performed by STP. The cost for this document is $50 per order. Both documents are electronically signed by the person performing the tests; however, an actual signed copy is available upon request.
