ASTM WK85542

Revision of A742/A742M-20 Standard Specification for Steel Sheet, Metallic Coated and Polymer Precoated for Corrugated Steel Pipe


The purpose of this work item is to open up the ASTM A742 specification to allow for thinner polymer coatings than the current 10 mil/10 mil minimum. This revision is based on a recent testing program conducted by NCSPA which demonstrated that thinner polymer coatings can be effectively used on small diameter pipe in low abrasion environments.
