Brief Analysis Of Technical Specification For Basic Safety Of National Textiles

GB18401 - 2010 "national textile product basic safety technical specification" (hereinafter referred to as the 10 edition standard) has been released in January 14, 2011. This version takes the place of the current GB18401 2003 (hereinafter referred to as 03 edition standard), which will be implemented in August 1, 2011.

The national basic safety technical specification for textile products is a mandatory national standard. It is a necessary condition for the product to enter the market and is the most basic technical requirement for ensuring the harmlessness of textile products to human health. It plays a very important role in the production and sale of textiles, as well as routine supervision and inspection.

Therefore, it is particularly important to correctly understand the standard provisions and clarify the difference between them and the 03 edition.

1 major differences and understanding of clauses

Compared with the 03 edition, the 10 edition standard has the following changes. It can be called the GB18401 - 2003 version.

One point one

The 10 edition of the standard applies in the scope of application, "this standard applies to the production, sale and consumption of domestic, textile and household textile products in our country.

Export products can be implemented in accordance with the contract agreement.

Note: the products listed in Appendix A do not fall within the scope of this standard, except as otherwise stipulated by the state. "

It can be seen that in the scope of application, "household textile products" are added, and "except for the agreement between the two sides of supply and demand" is deleted, that is, as long as it is produced and sold in our country, whether it is a separate agreement between the supplier and the buyer or imported textile products, it must meet the technical requirements of this standard, which is universal and mandatory.

Appendix A, which does not fall within the scope of this standard, further defines the scope of application of this standard, adds "disposable sanitary products", "bags, back bags, shoes, umbrellas, etc.", "carpet", and changes "decorative items such as decorative cloth, handicraft and other decorative objects" into "cloth arts and crafts".

1.2 infants

The definition of infant textile products is changed to "textile products worn or used by infants aged 36 months or less" by the 03 edition of "textile products worn or used by infants aged 24 months or less".

At the same time, the applicable height of the 5.3 notes should be changed from "80cm" to "100cm".

Compared to the 03 edition, the 10 edition of the definition of infant textile products is more extensive, closer to the actual situation of infant height, and also puts forward higher technical requirements for infant textile products.

1.3 product classification and basic

In the 10 version of the standard clause 4.1, the representation method of product classification is changed from "A, B and C code + text description form" to express the classification method directly in the form of text description.

Clause 5.2 is changed to "infant textile products should meet category a requirements. Products directly exposed to skin should at least meet the technical requirements of category B products. The products that are not directly exposed to the skin should meet the requirements of category C at least", adding "at least" words.

The understanding of this change is very important.

The product classification and basic safety technology requirement category in the 10 edition are two different concepts. Product classification is the classification of textile products according to the end use of products (Appendix B gives classification examples), while category A, B and C represent technical requirements, and there is no corresponding equivalent relationship between them.

The 03 edition standard is not clearly differentiated, generally understood as the corresponding relationship.

Because of this, after the implementation of the 10 edition standard, there are some puzzles in the format of the use note.

1.4 "4- amino azobenzene" was added to the carcinogenic aromatic amine.

The carcinogenic aromatic amines in Appendix C of the 10 edition increased the "4- amino azobenzene", and the number of carcinogenic aromatic amines increased from 23 to 24.

Relative to the 03 edition, the 10 edition of the standard is more stringent for the control of toxic and harmful substances, and it also puts forward higher requirements for the ability of inspection institutions.

In the normative citation, GB/T23344 was added, and GB/T17592.1 was changed to GB/T17592. In addition, the limit value of decomposable carcinogenic aromatic amine was added to the footnote C in Table 1, which was less than 20mg/kg, which improved the operability of carcinogenic aromatic amine detection.

At the same time, the detection of 4- azobenzene was specified in Clause 6.8. "In general, GB/T17592 is detected first and then detected by GB/T23344 when aniline or 1,4- benzene two amine is detected."

Changes in 1.5pH value requirements

In Table 1 of the 10 version of the standard, the pH value of class B products is relaxed from 4.0~7.5 to 4.0~8.5. Compared with the 03 version, the requirements are in line with the actual production situation of China's textile dyeing and finishing industry. Taking into account the influence of water quality differences and waste of water resources in different regions of China, the cost of dyeing and finishing enterprises has been reduced to a certain extent.

At the same time, the 10 edition standard added "non final products" in footnote a to table 1, and made more explicit provisions for products that can be relaxed to 4.0~10.5 for easy understanding.

1.6 instructions for color fastness assessment

The footnote B of Standard Version 1 of the 10 edition is changed from "washing and discoloring products not required" to "non final products, natural color and bleaching products that need washing and discoloring process," and traditional hand-made coloring products such as tie dyeing and batik dyeing are not required; saliva fastness is only tested on textile products of young children. "

At the same time, clause 5.2 added "decorative products such as curtains and suspension products not to assess the color fastness to perspiration".

This makes it even clearer to point out that if washed jeans are the final product, color fastness is also needed.

The 10 version of the standard added some color fastness assessment, such as hand coloring products, natural and bleaching products, better reflects the adaptability and pertinence.

In addition, the 10 edition also made some other changes, such as adjusting some examples in Appendix B, adding appendix D, including the contents of the 7.4 note.

2 recommendations

How long is the pition period between the old and new standards?

How should the instructions for overuse be identified?

Do you need to mark the year number in the logo?

How should the standards be implemented during the pition period?

No specific implementation details have been announced.

In addition, different inspection institutions and enterprises have different interpretations, which bring some troubles to enterprises and inspection institutions.

Therefore, it is recommended to amend the implementing regulations of the People's Republic of China standardization law as soon as possible or to formulate relevant implementation rules for the pition period of the old and new standards.

The presentation methods of product classification and basic safety technical requirements mentioned in the 10 edition have changed. However, some of the new product standards have not yet been updated. They follow the 03 version of the standard presentation method, which brings confusion to the use of the product description and the selection of safety technology categories.

For example, the industry standard FZ/T81007 - 2003, "single and clip clothing" 3.12.7 stipulates: "the pH value of the finished product is limited, and the garment that directly contacts the skin is 4.0~7.5". 3.12.8 stipulates: "the pH value of the finished product is limited, and the garment that is directly exposed to the skin is 4.0~9.0". When the garment executes GB18401 2010 and FZ/T81007 2003, it will produce ambiguity and bring different understandings, such as:

A) if the product instructions are identified as "GB18401 2010B class" and "FZ/T81007 2003", the product classification is not marked, then the pH value of the product may be 4.0~7.5 or 4.0~9.0, according to the requirements of FZ/T81007 2003.

The requirement of pH value for GB18401 - 2010B products is 4.0~8.5.

In the case of supervision and inspection, if the test result of the pH value is 8, if the product is strictly judged, the product is not qualified, and the enterprise decides that the product is a textile product which is not directly exposed to the skin. According to the 4.0~9.0 specified in FZ/T81007 - 2003, combined with the requirements of GB18401 - 2010B, the requirement should be 4.0~8.5, which is qualified.

First of all, marking the "GB18401 2010B class" is definitely correct, because GB18401 2010 does not require labeling products, while product classification is not clearly defined. Some clothing products may be directly related to skin textile products, or may be non direct contact with skin textile products.

B) another explanation for similar situations is that product classification is required, that is, product category is identified in the logo, which will cause trouble for the annotation of the instructions.

Because in accordance with the understanding of the 10 edition of standards, in addition to infant textile products, marking the word "baby products", it is not appropriate to mark in the form of text.

At present, different inspection institutions have different interpretations, which also bring trouble to textile and garment enterprises.

In view of the above reasons, the individual recommends that the Standardization Committee and the relevant units of standard setting make supplementary remarks on the identification format and the selection of the index after the implementation of the GB18401-2010 standard, so as to unify the understanding of this standard by the inspection organizations and enterprises.

Recommendations can be marked according to product classification, for example, infant textile products: "basic safety technical requirements: infant products"; direct contact with skin textile products, annotated format: "basic safety technical requirements: class B" (or class a); non direct contact with skin textile products, annotation format: "basic safety requirements: class C" (or category A or B class), or can also be marked according to the "implementation standard: product standard GB18401B class" format.

After the implementation of GB18401 - 2010, when the formaldehyde and pH values stipulated in the product standards cause conflicts with GB18401-2010 due to the change of expression mode, they should be judged according to GB18401-2010.

This will not only straighten out the relationship among the standards, facilitate the labeling of products, but also avoid the quality control of related enterprises such as dyeing and finishing clothing, and also coincide with the original intention of relaxing the pH value index when revising GB18401 - 2010.

In addition, the formaldehyde, pH value, carcinogenic aromatic amine and odor can be directly executed according to the requirements of GB18401 when the product standard is updated.

3 conclusion

The 10 edition of the national basic safety technical specification for textile products has a wider coverage and stricter control of toxic and harmful substances compared with the 03 edition, which fully reflects the importance of the product quality and safety in 12th Five-Year.

Its implementation will more effectively protect the safety and health of our consumers, and more effectively guide textile related enterprises to further improve the awareness of quality and environmental protection, and advocate low-carbon energy saving, so as to respond calmly to international trade protection and enhance the competitiveness of China's textile and garment enterprises in the international market.

At the same time, the standard setting units and the supervision and inspection institutions should strengthen the propaganda, publicity and guidance of standards, unify the understanding and application of standards, and make the new standards play a better role.
