Significance and Use

This practice facilitates the selection and application of an insulation system for use at service temperatures between 30 and + 107°C (22 and + 225°F). Although the successful installation of spray-applied PUR/PIR is influenced by many factors, this practice treats those four areas found to be of major importance:

(1) Substrate preparation,

(2) Substrate priming,

(3) Insulation application, and

(4) Protective coatings.

Abrasive blasting, primer application, spray application of the insulation, and protective coating application each contribute their unique health and safety hazards to the job site and will be dealt with in more detail under their respective headings.

1. Scope

1.1 This practice concerns itself with the substrate preparation and priming, the selection of the rigid cellular polyurethane system, and the protective insulation coatings for outdoor service equipment.

Note 1--For the purpose of this practice, polyurethane is defined to mean either polyurethane or polyisocyanurate and is hereafter referred to as "PUR/PIR."

1.2 The values given in inch-pound are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
