Rationale

ASTM C1936 “Standard Test Method for Corrosiveness of Mineral-Fiber or Cellulosic-Fiber Insulation by Comparison to Control” was created as a separate Test Method, extracting it from ASTM C665 “Standard Specification for Mineral-Fiber Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing”. Since this Standard referenced the embedded test method in C665, this revision changes the reference to the new separate C1936 Standard.
