Quality inspection report is based on standardized requirements, products and projects for quality testing and quality supervision, and to analyze and study the written report reflecting the quality of products and projects, it is the results of quality inspection and quality information feedback carrier, in economic activities, it has become the quality of the management tools to hold the quality gate, and become the maintenance of the normal social and economic order, safeguard the legitimate rights and interests of users and the implementation of arbitration. The basis for the implementation of arbitration.

Test report test standards

Test standards are in order to obtain a good order within a certain range, developed by consensus and approved by the recognized institutions, for a variety of activities or their results provide rules, guidelines or characteristics for common use and repeated use of a document. The main test standards are: GB (national standards), QB (industry standards), enterprise standards, special standards and so on. In addition, if the product is special, there is no corresponding test standard, the applicant can provide their own test basis for product testing.

General common test products are divided into four categories:

1. Household appliances GB4706 standards for testing

2.AV audio and video GB8898 standards for testing

3.IT information technology class GB4943 standards for testing

4.LED lamps and lanterns GB7000 standards for detection

Conventional testing items are: fiber content, pH value, formaldehyde content, decomposition of carcinogenic aromatic amine dyes, color fastness.

Fiber content

As the name suggests is to detect the fiber composition of textile raw materials and its content, the fiber content of raw materials will directly affect the quality of the finished product, so the fiber content is the most basic and important items in the textile testing.

pH value

Textile printing and dyeing process dyes are more or less not fully washed or neutralized, resulting in fabrics too acidic and alkaline, beyond the pH value of the human skin adaptive range, it is easy to cause skin itching, allergies, inflammation and other diseases, affecting human health. In order to improve the textile taking safety performance, so the pH value is also an important indicator.

Formaldehyde content

In the production of fabrics, in order to achieve anti-wrinkle, shrinkage and other effects, or in order to maintain the durability of printing, dyeing, or in order to improve the feel, it is necessary to add formaldehyde in the additives. Formaldehyde-containing textiles, in the process of people wearing and using, will gradually release free formaldehyde, thus jeopardizing the health of the wearing population, therefore, formaldehyde content is also one of the important indicators of textile testing.

Decomposable Carcinogenic Aromatic Amine Dyes

It refers to the dyes synthesized by carcinogenic aromatic amines, which are often called "banned azo dyes". For textile safety indicators, the toxicity and carcinogenicity of decomposable aromatic amines are much stronger than that of formaldehyde. Because formaldehyde has an irritating odor, easy to distinguish, and soluble in water, consumers buy back textiles, generally wash with water to remove most of the formaldehyde; but can be decomposed aromatic amine dyes made of clothes, not only insoluble in water, and colorless and tasteless, from the appearance of the textile can not be distinguished, only through the technical test can be found, and can not be eliminated, the dyes in contact with the human skin, can cause a variety of malignant diseases, absorption of carcinogenicity. After contacting with human skin, this kind of dyes can cause many kinds of malignant diseases, absorb and cause cancer. Therefore, the importance of detecting decomposable carcinogenic aromatic amine dyes can be imagined.

Color Fastness

The ability of dyestuffs to maintain their original color and luster when they are used or processed after dyeing and finishing by various external factors. The color fastness is assessed according to the discoloration of the specimen and the staining of the undyed lining fabric.

Conventional color fastness includes: soap fastness, water fastness, sweat fastness, rubbing fastness, light fastness, light and sweat fastness. Conventional color fastness (except light fastness) has 5 levels, 1 level is the worst, 5 level is the best; light fastness has 8 levels, 1 level is the worst, 8 level is the best.
