Foreword

GB/T 13835 "rabbit fiber test method" consists of the following nine sections.

--- Part 1. Sampling;

--- Part 2. The average length and short hair ratio manual transmission method;

--- Part 3. impurity rate, coarse hair and loose hair rate;

--- Part 4. Regain oven method;

--- Part 5. single fiber breaking strength and elongation at break;

--- Part 6. diameter projection microscopy;

--- Part 7. whiteness;

--- Part 8. ether extract content;

--- Part 9. crimp performance. This section GB/T 13835 Part 1. This Part replaces GB/T 13835.1-1992 "angora fiber test sampling methods." This section compared with the GB/T 13835.1-1992 The main changes are as follows:

--- Modify the method and amount of extracted sample batch and batch-like moisture regain (1992 version 4.1; this version 4.1);

--- Modify the sampling method and sample laboratory test sample (1992 version

4.2 edition and 4.3); Inner

--- to regain a lot sample drawn into a given weight of time from within 24h 4h (version 4.1.3 1992; this version 4.1.1). This section proposed and managed by China Fiber Inspection Bureau. This section is drafted. Sichuan Provincial Fiber Inspection Bureau, Zhejiang Province Fiber Inspection Bureau, Jiangsu CIQ. The main drafters of this part. He Hao, who Rong, Yu Suying, Liu Cai Rong, Wang Hsiao-ping. This part of the standard replaces the previous editions are.

1 Scope

GB/T 13835.1-2009 is the Chinese national standard on test method for rabbit hair - part 1: sampling, in the field of textile and leather technology. 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 April 2009 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 September 2009. Classification: ICS 59.060.01, CCS W20. 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.

GB/T 13835 provisions of this part of the batch extraction rabbit-like, method and number of laboratory samples, test sample. This section applies to rabbit sampling inspection and test time.
