Anotácia textu normy ASTM C318/C318M-13(2018) :
This specification covers the minimum requirements for gypsum formboard designed for use as a permanent form for poured-in-place reinforced gypsum concrete roof decks. Gypsum formboard shall consist of a noncombustible core, essentially gypsum, either mineral or organic, synthetic or natural. The face surface shall be specifically treated to resist fungus growth. Specimens shall be subjected to the following test methods: flexural strength; humidified deflection; core, end, and edge hardness; and resistance to fungi. Specimens shall be tested to determine thickness, width, length, end squareness, and edges and ends. The surfaces of gypsum formboard shall be true and free from imperfections that would render it unfit for use with or without decoration.
