Foreword

This standard rule according to GB/T 1.1-2009 given draft. This standard replaces GB/T 11277-1989 "surfactants non-ionic surfactant cloud point index (water number) Determination of capacity Method ", compared with the GB/T 11277-1989, the main changes are as follows. --- Increasing the foreword; --- Reducing the extent of adoption as "revised adoption"; --- Added "sampling" (see Chapter 7); --- Added "the test report" in a) and e) (see Chapter 10); --- Increase the informative Appendix A. This standard uses redrafted law revision adopted ISO 4320.1997 Capacity Determination "non-ionic surfactant cloud point index law". This standard and ISO 4320.1997, compared with more adjustment in the structure, listed in Appendix A of this standard and ISO 4320.1997's Reg number control list. This standard and ISO 4320.1997 and the technical differences for the following reasons. --- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustments are as follows. ● equivalents adoption of international standards GB/T 6372-2006 instead of ISO 607. 1980 (see Chapter 7); ● increase cited GB/T 6682-2008 (see 5.1); ● increase cited GB/T 11275-2007 (see 5.2). --- Remove ISO 4320.1997 Chapter 8, "Sample." The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee Chemistry (specialty) surfactant Technical Committee (SAC/TC63/SC8) centralized. This standard was drafted. Zhejiang Real Technology Co., Ltd. The main drafters of this standard. Tangfu Wei, Qian Jian Fang, Liu Zhixiang, Yan Ji school. This standard replaces the standards previously issued as follows. --- GB/T 11277-1989. Surfactants non-ionic surfactants Determination of cloud point index (water number) - Volumetric method

1 Scope

This standard specifies a method of non-ionic surfactant cloud point index measured --- volumetric method. This standard applies to low alkoxylated nonionic surfactant (1 to 5 ethylene oxide groups), its hydrophobic group is composed of alcohol/alkylphenol Or fatty acid provided (melting point thereof is lower than 30 ℃). This standard also applies to the alcohol, alkyl phenol or fatty acid-derived lipophilic group thereof.
