Foreword

This standard by the National Standardization Technical Committee Feed Industry and focal points. Drafting of this standard. National Feed Quality Supervision and Inspection Center (Wuhan), Huazhong University of Science and Technology. The main drafters of this standard. He Yifan, Xu Jinping, Liu Xiaomin, Yang Lin, Yang Xiankui. This standard is the first release.

Introduction

Given the natural zeolite content changes, can not be accurately measured by chemical methods. But the amount of absorption of ammonia content of the zeolite is linear, so This standard differential determined on the basis of zeolite, measuring the amount of ammonia absorption to determine how much product zeolite content. Feed-grade zeolite powder

1 Scope

This standard defines the quality of feed grade zeolite powder requirements, test methods, inspection rules and labels, packaging, transportation and storage. This standard applies to feed-grade zeolite powder.
