Rationale

In ASTM C553, Section 6.2 is information on facings that could be supplied with these insulations. Section 6.2.3 gives some "typical" facings but is not a complete list nor has it been updated. During the reviews in Toronto and Atlanta, it was discussed to update the list but the consensus was to remove section 6.2.3 as the section 6.2.1 states the facing can be specified by the purchaser.
