Scope

This document specifies the terminology definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and sales and service requirements for edible-grade zeolite powder. This document applies to edible-grade zeolite powder prepared from natural clinoptilolite as raw material. When used in the food industry as food additives and other purposes, it shall also comply with the provisions of relevant laws and regulations. 5. Technical Requirements 5.1 Raw Mineral Requirements It shall comply with the requirements of Table 1.
