Anotácia textu normy ASTM A849-15(2021) :
This specification covers post-applied coatings, pavings, and linings for corrugated steel pipe and corrugated steel structural plate pipe, pipe-arches, and arches coated, paved, or lined with specified materials over either metallic coatings or metallic coatings with polymer coatings. Asphalt, polymerized asphalt, polymer, mastic, and emulsion coatings and asphalt and concrete pavements and linings are included. Two-step classification procedure is used to describe post-applied coatings, pavings, and linings. The first classification is based on the type of coating, paving, or lining material to be used. The second is a coating, paving, and lining type giving the physical location of the coating or lining on the pipe.

1.1?This specification covers post-applied coatings, pavings, and linings for corrugated steel pipe and corrugated steel structural plate pipe, pipe-arches, and arches coated, paved, or lined with specified materials over either metallic coatings or metallic coatings with polymer coatings. This specification includes asphalt, polymerized asphalt, polymer, mastic, and emulsion coatings and asphalt and concrete pavements and linings applied to the pipe in the producing plant, as well as, asphalt and mastic coatings applied in the field. Field-applied concrete pavements and linings are covered by Specification A979/A979M. The pipe to which the coatings are applied is described in Specifications A760/A760M, A761/A761M, and A762/A762M. 1.2?There is no cleaning operation currently included in pipe coating practice. However, experience has shown that a clean substrate provides good adherence for both cold- and hot-applied post coatings. The performance of post coating or lining, or both, will depend on the surface cleanliness over which it is applied. 1.3?The values stated in inch-pound units are to be regarded as standard. The values given in brackets are for information only. 1.4?The following safety hazards caveat pertains only to the test methods portions, Sections 11 and 12, of this specification. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
