Dongying Bureau Of Industry And Commerce: 6 Batches Of Footwear Products Failed To Spot Checks

< p > the sampling basis for this footwear commodity is QB/T1002-2005 "leather shoes", "GB/T15107-2005" travel shoes "and" GB 20400-2006 "the limits of harmful substances in leather and fur.

The test items are: General requirements (shoe number), sensory quality, peel strength of the bottom, upper strength, folding resistance, wear resistance of the outsole, adhesion strength of the sole and outer middle sole, heel binding force, formaldehyde content and azo 10 indexes.

< /p >

< p > < strong > main problems are: < /strong > < /p >.

< p > < strong > (1) < a href= > http:// > www.91se91.com/news/index_c.asp > formaldehyde > /a > 1 batches are not qualified < /strong > /p >

< p > < < a href= "http://" www.91se91.com/news/index_c.asp > > leather shoes < /a > the formaldehyde content of leather parts directly contacted with the skin exceeds the limit value of the compulsory standard GB 20400-2006 standard.

Formaldehyde is a volatile and toxic chemical substance. It has strong irritation and stimulates human eyes and respiratory system. It also induces mutation and carcinogenesis. Therefore, the content of formaldehyde is an important safety technical index of products.

< /p >

< p > < strong > (two) < a href= "http://? www.91se91.com/news/index_c.asp" > folding resistance < /a > 2 batches of unqualified < /strong > /p >

< p > 1. the main problem is that the length of the sole cut exceeds the standard requirement after some leather shoes are tested.

< /p >

< p > 2. parts of leather shoes after the folding test appeared to help or cover the bottom.

< /p >

< p > folding resistance is one of the main indicators of the internal quality of footwear products, which reflects the service life of footwear products.

By simulating the endurance test of the continuous walking state of the human feet, it can directly reflect the strength and toughness of the shoe's surface and base, and the overall quality of the bottom and the fastness of the strip, and other important properties such as the durability and durability of the shoes, such as whether the new cracks on the vamp are produced, whether the opening of the sole is expanded or not.

The results of the folding test directly affect the quality of the shoes.

< /p >

< p > < strong > (three) the wear resistance of the outsole has 1 batches of unqualified < /strong > < /p >.

< p > 1 batches of shoe sole wear marks exceed the standard required length.

The wear resistance of sole is one of the important quality indexes of footwear products, which reflects the service life of footwear products.

In the process of wearing shoes, the soles will be subjected to repeated rubbing forces, so the wear resistance of the soles is an important index to measure the quality and durability of shoes.

< /p >

< p > < strong > (four) shoe number has 2 batches of unqualified < /strong > < /p >.

< p > this quality sampling inspection found that 2 batches of shoe shoes were not qualified, mainly because they were not marked with Chinese shoe numbers, incomplete marking (unlabeled shoe type) or wrong marking.

According to the national footwear standard GB/T3293.1, shoes and inner packages, such as shoe boxes, must be marked with the current Chinese shoe number.

The shoe number includes the foot length indication value. If necessary, it needs to mark the foot width value, and the two value is expressed in millimeter integers (not indicating units).

Improper marking of shoes will affect the correct choice of footwear products.
