Basic Information
Scope
This standard specifies the classification, requirements, test methods, inspection rules, marking, and transportation and storage of magnesium-lime composite materials for agricultural greenhouse frames.
This standard applies to magnesium-lime composite materials for agricultural greenhouse frames made with modified magnesium-lime cement (magnesium chloride cement) as the binder material and fine bamboo fibers or other non-metallic materials as the reinforcing materials; it applies to magnesium-lime composite materials for agricultural greenhouse frames with a frame spacing of no more than 3 m and a span of no more than 10 m. This standard does not apply to products that use high-alkali glass fiber cloth (or yarn) as the reinforcing material.
