Feed-grade dicalcium phosphale (bone)2005-07-26 Issued
National Development and Reform Commission of the People's Republic of China 2006-01-01 Implementation
This standard is a revision of (BT2355-199% feed magnetic acid oxygen (Japanese 3). The main modifications are as follows: Cancel the classification of calcium phosphate oxygen:
. Adjusted the technical indicators of sound analysis;
- Modified the inspection rules and regulations, packaging, transportation and other aspects. This standard is proposed by China Light Industry Federation. This standard is under the jurisdiction of Gelatin Branch of China Chemical Industry Association: QB/T2355-2005
This standard is the responsibility of the National Light Industry Rubber Product Quality Supervision Center (Beijing) from 2004 to 2006, and is participated by Gulin People's An Gelatin Co., Ltd., Qinghai Gelatin Co., Ltd. and Dongming Zheng Co., Ltd. This standard was first issued in 1987 and revised for the second time in 1998. This standard is the first European standard issued by the European Commission and replaces the previous standard Q0/T2355-1998 issued by the China Association for Light Industry. The standard specifies the requirements, test methods, inspection rules and signs, packaging, transportation, etc. for calcium phosphate (bone) in feed. This standard is applicable to the gelatin production industry and the animal feed is subjected to the acid nitrogen (CaH4.2H0) when gelatin is extracted. 2 Normative references Documents
