Zhejiang Provincial Consumer Protection Committee To Carry Out Roller Skates Product Safety Test Results Are Not Ideal.

The Zhejiang Consumer Protection Committee recently launched a test on safety products of roller skates.

Test results show that 5 of the products do not meet national standards.

According to the introduction, the Zhejiang Provincial Consumer Protection Committee in mid December 2015 selected five shopping malls (Decathlon (Hangzhou) Sporting Goods Co., Ltd. Daguan store, Hangzhou Auchan supermarket limited, Daguan store, Huarun Wanjia life supermarket (Zhejiang) Limited company Yunhe store, Zhejiang Century Lianhua supermarket limited, Wen two West Road store, Hangzhou Wumart Commercial Co., Ltd. Mogan Shan Road store) in the middle of Chengbei, Chengdu West and other large residential areas, and purchased 10 samples of leisure single row roller skates for children, adolescents and adults. The production sites involved 4 provinces and municipalities in Zhejiang, Shanghai, Guangdong and Jiangsu.

This sampling inspection focuses on the mandatory provisions items involved in sports safety, including touches, fasteners, adjustment mechanisms, and operability.

Bearing, shaft exposed parts, shoe and wheel rack fastness test, vertical impact test, wheel, brake and so on.

The inspection is based on the national standard GB 20096-2006 "roller skates" and GZ 24230102 roller skates 111-2015 "Zhejiang province roller skates product quality supervision, inspection and evaluation rules" product quality indicators and the relevant provisions of national laws, regulations, rules and regulations.

The comparison test showed that the 5 batches which met the requirements of national standards and evaluation rules were not in conformity with 5 batches.

The main items that do not conform to the project are: brake (beyond wheel distance, distance from the lower end to the ground, the angle between the horizontal line of the wheel and the ground), "wheel (friction coefficient, durability)" and "shaft exposure part (length, chamfer)".

Roller skating is a sport with certain danger. The brake project is the mandatory requirement of the national standard for roller skates, and it is the key index to inspect the quality of roller skates.

Especially for children, it is particularly important to brake in time to avoid danger in the high-speed sliding process.

According to the national standard,

Brake safety requirements include 3 aspects: installation of brake roller skates, brake should exceed 10mm above the wheel frame, brake area is not less than 300mm2, the distance between the lower end of the brake and the ground is not less than 10mm, and when the brake contacts with the ground, the angle between the horizontal line of the wheel and the ground is 12 degree ~25 degrees.

These 3 aspects directly determine the actual braking effect of roller skates.

In addition, the national standard stipulates that the safety requirements of the single row roller skates for leisure include 2 aspects: the friction coefficient of the wheels should not be less than 0.3; after the frontal impact and endurance tests, the connectors can not be loosened, damaged, deformed and obstructed.

The safety of the exposed parts of the single row roller shoes for leisure is: the exposure length of the shaft is not more than 3mm, and the exposed ends should have chamfering radius of not less than 5mm. After the durability test, it will not loose, no displacement and no deformation.

During the inspection process, it was found that the brake failed to meet the standard requirements.

(1) the "ROLLER skates" brakes produced by Shanghai Xinwei Sports Products Co., Ltd. are only 4mm above the wheel frame. The "advanced training skates" brake of the specification type "DC2010-A" produced by Zhaoqing Chuan Yue Sports Industry Co., Ltd. is only 7mm above the wheel frame.

Because the brake exceeds the wheel length does not meet the specified requirements, it will directly cause the contact area between the brake and the ground to decrease, and it will be difficult to brake when the speed of sliding is fast.

(2) Hangzhou Yu Chen outdoor products Co., Ltd. produces a specification "WS-0707", "straight row roller shoes" brake, the distance from the bottom to the ground is 8mm, and the angle between the horizontal line of the wheel and the ground is only 8 degrees.

This does not meet the requirements of children and teenagers. Because of the gliding angle or uneven ground, the children and teenagers are forced to brake at the lower end of the brake when they are in contact with the ground, causing children to suffer from sports injuries such as falls, sprains, and even serious fractures.

During the inspection process, it was found that the wheel did not meet the standard requirements.

(1)

The "TC106-11" "adjustable roller skates" produced by Minhe outdoor sports products Co. Ltd. and the "straight row skates" produced by Shanghai Le Shi sporting goods Co., Ltd., the friction coefficients of the two batches of wheels are only 0.2, and the wheel friction coefficient is too small, which will cause the grip strength of the roller skates to drop greatly, and it is easy to slip in sliding, causing the sports injuries such as collision and fall;

(2) the "ROLLER roller skates" produced by Shanghai Xinwei Sports Products Co., Ltd., the "DC2010-A" "advanced training skates" produced by Zhao Qingchuan Vietnam Sports Industry Co., Ltd. and the "straight row skates" produced by Shanghai Le Shi sporting goods Co., Ltd., and the three batches of wheels after the endurance test, all appeared the phenomenon that the wheels damaged, deformed and prevented from sliding, which did not meet the standard requirements.

This means that the wheel wear resistance is poor and wear is large. When passing a slight bumping section, it is easy to occur the overall deformation of wheels, seriously hamper the normal sliding, and easily cause impact and other hazards.

During the inspection process, it was found that the exposed parts of the shaft did not meet the standard requirements.

(1) the shafts of the "ROLLER roller skates" produced by Shanghai Xinwei Sports Products Co., Ltd. have not been processed, resulting in too small.

(2) the length of the exposed parts of the "straight row skates" produced by Shanghai Le Shi sporting goods Co., Ltd. is 4mm, and the chamfer radius is less than 5mm.

The existence of these two dangerous parts can easily cause serious injuries such as scratches or stab wounds when colliding or scraping with others. When skating or bumping at high speed, it is easy to cause serious harm to oneself.

Consumer prompts

Consumers need to consider the following points when choosing roller skates.

1. when consumers purchase roller skates, they should check whether the products have detailed instructions.

Carefully check whether the tag is marked with product name, corresponding execution standard, specification, type, producer name and address, and check whether there are shoe numbers or specifications on the shoe body.

Do not purchase products with no identification or identification information.

2. generally speaking, wheels and bearings are the key to roller skates. The finer the bearings, the bigger the diameter of the wheels, the better the material and the faster the speed. The longer the bearings are, the more delicate the quality is.

Bearings with uniform rotation and rotation time of about 15 seconds are better quality bearings.

The choice of wheels depends on the different venues.

Wheel size should not be too large, 80mm is the upper limit.

3. the thicker the boot is, the softer the tongue is, and the more comfortable it is, the better the protection for the foot will be when the impact occurs. The sponge must be thick and sticky.

When buying shoes, one touch is done by hand. Two is to buy good roller skates with feet. The better the shoe buckle is, the better the shoe will not loose even if it falls down in sports.

It can play a good role in protecting the ankle.

4. in practical use, protective clothing should be worn and safety precautions should be made.
