abstract
This specification covers the testing and material properties of water-dispersed protective roof coatings composed of water-based acrylic latex elastic emulsion polymers, where a variety of pigments and other additives are added to provide the desired physical properties. The manufactured product shall be in liquid form and may be applied to the roof surface by brushing, scraping, rolling or spraying. Its application guide is not discussed here. The coating must be tested and meet the liquid characteristics required for solid viscosity, volume and weight. Conversely, the film should also conform to the physical properties of drying as follows: initial elongation at break; Initial tensile strength under maximum stress; The final elongation at break after accelerated weathering; Through; Edema; Adhesion force; Fungal resistance; 引裂き抵抗; And low temperature flexibility after accelerated weathering.

範囲
1.1 This specification covers liquid application of water-dispersed acrylic latex elastic protective roofing coatings.

1.2 This specification does not provide guidance for application.

1.3 SI 単位またはインチポンド単位で表された値は標準値として別個に扱われます。. The values specified in each system may not be completely equivalent; したがって, each system should be used independently of each other. Combining values from two systems may result in nonconformity.

1.4 この規格はすべてに対処することを目的としたものではありません, もしあれば, その使用に伴う安全性の懸念. 適切な安全性を確立するのは、この規格のユーザーの責任です。, 健康および環境慣行を確認し、使用前に規制制限の適用可能性を判断するため.

1.5 この国際規格は、国際規格開発の原則に関する決定で確立された国際的に認められた標準化原則に基づいています。, WTO貿易の技術的障壁に関する委員会が発行したガイドラインと勧告.
