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; Rezistenta la rupere; And low temperature flexibility after accelerated weathering.

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; Prin urmare, fiecare sistem trebuie utilizat independent unul de celălalt. Combining values from two systems may result in nonconformity.

1.4 Acest standard nu este destinat să se adreseze tuturor, dacă există, probleme de siguranță asociate cu utilizarea acestuia. Este responsabilitatea utilizatorilor acestui standard să stabilească siguranța corespunzătoare, practicile de sănătate și de mediu și pentru a determina aplicabilitatea restricțiilor de reglementare înainte de utilizare.

1.5 Acest standard internațional se bazează pe principiile de standardizare recunoscute la nivel internațional stabilite în Decizia privind principiile pentru elaborarea standardelor internaționale, Orientări și recomandări emise de Comitetul OMC privind barierele tehnice în calea comerțului.
