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. Umgekehrt, 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; Reißfestigkeit; And low temperature flexibility after accelerated weathering.

Reichweite
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 Values expressed in SI units or inch-pound units shall be treated separately as standard values. The values specified in each system may not be completely equivalent; daher, each system should be used independently of each other. Combining values from two systems may result in nonconformity.

1.4 Dieser Standard soll nicht alle ansprechen, wenn überhaupt, Sicherheitsbedenken im Zusammenhang mit seiner Verwendung. Es liegt in der Verantwortung der Anwender dieser Norm, für angemessene Sicherheit zu sorgen, Gesundheits- und Umweltpraktiken zu prüfen und vor der Verwendung die Anwendbarkeit behördlicher Beschränkungen zu ermitteln.

1.5 Dieser internationale Standard basiert auf den international anerkannten Standardisierungsgrundsätzen, die in der Entscheidung über Grundsätze für die Entwicklung internationaler Standards festgelegt sind, Leitlinien und Empfehlungen des WTO-Ausschusses für technische Handelshemmnisse.
