National Standard For Footwear Steel Hook Heart Was Drawn Up In September.

The National Standard Committee announced through the website that the national standard committee recently decided to revise the national standard of "shoe steel hook heart", increased the concept of "heel height" of high-heeled shoes, and made clear the decision method. The revised standard was promulgated in the form of amendment No. first, and it will be implemented in September 1st this year.

It is reported that steel hook heart is an important part of footwear products. It is the "backbone" of shoes that is installed between the sole and the bottom of the shoe. It plays a role of bearing and balancing, determines the stability and comfort of shoes when worn, especially for medium and high heeled shoes. In order to guarantee the quality of steel hooked core, China has formulated the mandatory national standard of GB 28011-2011 "shoe steel hook heart", which has provided important indexes such as length, rigidity, hardness, bending property and fatigue resistance of steel hooked core. "Shoe tie hook" was released in 2011, and played a positive role in the development of shoemaking industry.

According to the introduction, during the implementation of the standard, it was found that some testing organizations and manufacturing enterprises had different understanding of heels with "high". Shoes The height of heel is different from that in the industry.

For the unified concept, the whole country Shoemaking The technical committee of the standardization has put forward the concept of "effective and high" after repeated discussions. "Effective versus high" means the difference between the heel height of the shoe and the thickness of the front part of the forehand, that is, the height difference between the heel and the front palm under normal wear condition. " Hooked steel for footwear The Revised Standard No. 1 of the national standard added the concept of "effective heel height", and made clear that "according to the measurement of the effective heel of the shoe, the various indicators of the hook should be judged".

The revision of this standard is convenient for footwear manufacturers and testing institutions to accurately understand the GB 28011-2011 "footwear steel hook heart", which is conducive to standardize the production and use of footwear steel hooks with standards, and promote the safety and quality improvement of footwear products.

Experts remind consumers that when choosing high-heeled shoes, you can use your hand to press the center of the shoe firmly, not soft or not. If the shoes are worn, they can be found to be skewed (not nailed or not fastened), or empty or uncomfortable, so that they can be sent to the footwear quality inspection agency to check whether the hook is deformed or broken.

Enclosure:

GB 28011-2011 revision of National Standard No. first of footwear steel hook heart

First, change the term "3 terms and definitions" to:

GB/T 2703 defines and the following terms and definitions apply to this document.

Three point one

Effective with high technical heel height; effective heel height

Heel height minus the thickness of the front palm.

Explain:

H- heel height

H - the thickness of the forehand area.

Two, the "8.2 footwear products in the examination of the heart" content is revised to:

8.2 inspection of hooks in footwear products

When sampling and inspection of footwear products, the number of samples can not meet the requirements of this standard, the 2 hooks removed from the same pair of shoes should be used as samples for inspection of all items. 2 marks for marking, appearance, size and hardness. After that, 1 hooks were tested for fatigue resistance and 1 for other projects. According to the effective heel of the shoes measured, the indexes of hook heart are determined.
