Active Standard: A27 / A27M - 13
The proposed changes will added clarity for use of this specification for ordering and manufacture of investment castings. The addition of a sentence at the beginning of the paragraph under Supplementary Requirements is so that it will read the same as the other steel casting specifications. The addition of A1067/A1067M as a reference is necessary because it contains the test coupon information formerly found in the common requirements specifications.
