Foreword

This standard uses redrafted law revision adopted ISO 5089. 1977 "Textiles laboratory samples for chemical testing and specimen Preparation "(in English), and ISO 5089. 1977 compared to the main changes are as follows.

--- Canceled ISO foreword;

--- Modify the terms and definitions;

--- The first four chapters 5, 6 and 7 combined into one chapter.

This standard replaces GB/T 10629-1989 "Textiles ready for chemical testing laboratory samples and specimens", and GB/T 10629-1989 main changes are as follows.

--- Increased introduction;

--- Modify the scope;

--- Modify the terms and definitions;

--- Certain provisions of Chapter 4 made editorial changes.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee on Basic Standards Subcommittee Textiles (SAC/TC209/SC1) centralized.

Drafting of this standard. National Textile Products Quality Supervision and Inspection Center.

Introduction

In the method given in this standard, the laboratory sample by sample from different parts of the batch extraction of many small samples thereof. Therefore, from any test results of samples obtained in these laboratory samples reflect only sample batch average, it does not reflect the difference between the various parts of the lot sample Different levels. This method is applicable to the assessment of the lot sample, such as a fiber component (as determined proportions of the different fibers in a blended sample), Does not apply to a very significant difference (such as when measuring pH value pH value of the sample pH value of one of its parts with other parts there is a difference Isobutyl; or in the determination of the content of fungicides, the content of a certain part of the sample is higher and lower levels of other parts). This method does not apply Determination of commercial quality.

Textile laboratory for chemical testing Preparation of samples and test

1 Scope

This standard specifies the number of samples taken from batches of textiles acquired laboratory sample, and gives the appropriate samples for chemical testing Appropriate size preparation.

The standard sampling method from the group of textiles is not specified, because we assume that the sample is granted through an appropriate program screened, it is possible Representative of the real situation of a group of textiles.

2 Terms and definitions

The following terms and definitions apply to this standard.

Depending on the purpose, according to raw materials, production processes and other division counts.

According to the provisions of a number of products at random from one or more of the packaging unit, as a laboratory sample source.

According to the provisions taken from the lot sample product unit or part of the material, as the test sample sources.

Samples taken from the laboratory for performing part of the test.

Principle 3

Laboratory sample representative of the batch sample, and the sample taken from the laboratory sample, each sample represents a laboratory sample.
