All technical contents of this standard are mandatory standardsForeword
This standard adopts the English Standard (P—230 Potassium Permanganate English version). This standard is based on the British Pharmacopoeia (BFV). The main technical characteristics of this standard and the British Pharmacopoeia (HP-2000) are as follows: GA2513-2C04 has been adjusted in the requirements for the technical indicators of chemical hooks and water-disordered substances (3.2 of this standard), which is to improve the quality control of the product; the requirements for the content of the spirit of the day have been added (3.21 of the standard). This is in accordance with the requirements of the Chinese Food Health Standard; the test method has been added with safety tips (. This standard is for "providing accurate sample testing and safety notes"; the test method adds the appropriate strategy of the pet method (4.7 of this standard): the shelf life of the product is increased (this standard range \). This standard GB2513-1087 food rising temperature standard. The main changes of this standard library compared with G25:31987 are as follows: the quality or fraction of high radiation is adjusted from small to large, from 2 to 9.%~10.5 (1.2 of the 1937 version. 3.2 of this version);
In the test method, the first Added safety environment indication (4.1 of the previous version) and identification of 1.% of the test method in this version. The supply method (2.1 of the 1997 version, 2) is adopted. The method specified in the Pharmacopoeia P-20003 is revised. The test method for the determination of the acid-free liquid phase of the chemical has been revised (2.2 and 2.8 of the 187 version, 1.5 of this version, 4. After the revision, the method specified in the Pharmacopoeia 1P-2000) is changed to the method specified in the Pharmacopoeia 1P-2000). Fangda (1987 edition 2.5.
