Foreword

The standard Chapter 6, Chapter 7 (except for test methods) are mandatory, the rest are recommended. This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB 1790-2003 "medicine Vaseline." The main differences between this standard and GB 1790-2003 are as follows. --- Added "Terms and Definitions", "characteristics" and "recognition" chapter (see 5 and 6); --- Increasing the "look" technical requirements (see 7); --- Remove the "characters", "UV absorbance," "heterosexual organic" technical requirements (see the 2003 edition 4); --- On the "dropping point", "penetration" and "sulfated ash" quality index has been modified (see 7, 2003 edition 4). This standard uses redrafted law revision by the British Pharmacopoeia BP-2008 in the "white petrolatum", "yellow Vaseline" (in English) prepared. test Into account China's national conditions, when employing BP-2008, made some changes in this standard. This standard BP-2008 version of the main differences. --- Increase the "scope", "normative references", "sample", "packaging, labeling, storage and delivery acceptance" and chapter; --- The standard reference standard using our corresponding national standards and industry standards; --- To increase the operability of the British Pharmacopoeia BP-2008 were refined, the British Pharmacopoeia BP-2008 version of "color" and "acid Alkalinity "test method as an appendix to this standard. This standard by the National Standardization Technical Committee on Petroleum Products and Lubricants made.
