Foreword

This standard replaces GB/T 10661-2003 "fluorescent whitening agent VBL". This standard and GB/T 10661-2003 compared to the main changes are as follows:

--- Standard name was changed to "fluorescent whitening agent VBL (CI fluorescent brightener 85)";

--- Increased CASRN resolution (Chapter 1 of this edition);

--- Combined for textiles and paper for two specifications (2003 edition Chapter 3, Chapter 3 of this edition);

--- Test items in the "relative strength" and "whiteness" to "whitening intensity" index modified accordingly (2003 Edition Chapter 3, edition Chapter 3);

--- Increasing the amount of indicators and test methods for heavy metal elements (Excerpts of Chapters 3 and 5.9);

--- Test method for increasing the strength of whitening (edition 5.4);

--- Cancel the relative strength and whiteness Test Method (2003 version

5.4 and 5.5). The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee Dye (SAC/TC134) centralized. Drafting of this standard. Zhejiang pass WHYYON Chemical Co., Ltd. Shanxi Qingshan Chemical Co., Ltd., Shenyang Chemical Research Institute Co. the company. The main drafters of this standard. Jiangdong Wen, Dong Zhongsheng, Gan Hongyu, bamboo one hundred Jun, Li Gang, Zhu Ye Qing. This standard was first published in 1989, 1996 and first revised in 2003 to the Second Amendment, this is the third revision. Fluorescent whitening agent VBL (CI Fluorescent Brightener 85)

1 Scope

GB/T 10661-2010 is the Chinese national standard on fluorescent whitening agent vbl (c.i. fluorescent whitening agent 85), in the field of paint and colour industries. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 December 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2011. Classification: ICS 87.060.10, CCS G57. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the fluorescent whitening agent VBL (CI fluorescent brightener 85) requirements, sampling, test methods, inspection rules and signs, Sign, packaging, transport and storage. This standard applies to fluorescent whitening agent VBL product quality control. Structure. Molecular formula. C36H34N12Na2O8S
