Scope

This document specifies the requirements for high-purity inner layer sand of quartz crucibles used for the growth of photovoltaic monocrystalline silicon, the inspection rules, and the marking, packaging, transportation, and storage, and describes the corresponding test methods.
This document applies to the production, inspection, delivery, and acceptance of high-purity quartz sand (hereinafter referred to as "quartz sand") used for the inner layer of quartz crucibles used for the growth of photovoltaic monocrystalline silicon, including natural quartz sand prepared from natural quartz ores or crystals through processing and purification, as well as synthetic quartz sand prepared from high-purity silicon-containing materials using physical and chemical methods.
