Full Description

1.1This practice covers the repair of spray-applied polyurethane insulation on vessels normally operating at temperatures between30 and+107C [22 and+225F].

1.2Warning-At temperatures below 0C [32F] the application of a spray foam directly onto the cold substrate may not be possible. The term foam applies to spray-applied polyurethane or polyisocyanurate (PUR or PIR) rigid cellular plastic only, and not to any other plastic insulation.

1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard.

Combining values from the two systems may result in non-conformance with the standard.
