Toe Protection - Protection Function Standard

One, Toe Protection - Standard Number: GB21148-2007

1 , static pressure resistance test

The main testing equipment: pressure testing machine

At a pressure of 15KN, the one minute test, the test is greater than 12.5-15 mm distance from the sole to the plasticine

2 , anti-impact inspection

Testing Equipment: Impact Testing Machine

23KG by the hammer 90 cm height impact test 12.5-15 mm greater than the distance from the sole to the plasticine

Second, the protection function standards

1 , pierce-proof - standard number: GB21148-2007

Four-point test for each shoe, the force required to penetrate the sole should not be less than 1100 cattle

2 , anti-static - standard number: GB21148-2007

Adjusted in dry and humid environment, the resistance value should be 100K ohms and 1000M Between Europe

3 , electrical insulation - standard number: LD12011-2009

Power frequency test voltage 6KV , duration 1 minute, leakage current 1.8 mA or less

Third, electrical insulation shoes GB12011-2009 standard requirements

1 , technical requirements

General requirements

Structure: There should be no metal hooks on the sole and heel. Electric insulating shoes with the function of protecting the toes shall be made of insulating materials inside the protective caps. If they are metal caps, they must be insulated to ensure that the insulation performance meets the requirements.

2 , electrical performance requirements

Fourth, protective function standard III

1 , oil resistance - standard number: GB21148-2007

According to GB / T20991 - 2007, when the detection method 8.6.1, is not more than 12% volume increase

If in accordance with GB / T20991 - after 2007 8.6.1 detection method, the sample volume shrinkage exceeds 0.5%, or increased hardness over 10 Shore A units, according to the GB / T20991 - 2007 for further sampling and testing methods 8.6.2 , continuous bending 150,000 times, incision growth does not exceed 6 mm .

2,   European anti-skid standard - standard number: EN ISO 20334:2004/ A1:2007

If both test environments pass, the highest standard SRC is non-slip .

Fifth, anti-skid test

1. Standards apply to safety shoes in traditional soles, non-special use products with spikes or metal nails

2 , non-slip interface for stainless steel plus glycerin and ceramic tile plus SLS (sodium dodecyl sulfate)

3 , require evaluation of the maximum code, the minimum code and the anti-slip performance of the middle code

Pre-test products need to be regulated ( 23 degrees, 50% relative humidity ) and tested in the same environment

The product is tested in three modes.

1, slide in front of the heel

2, after the forefoot slide

3, flat front slide

Six, anti-skid test - test results

Seven, protective shoes selection

TAI2866 new stylish multi-function rescue boots

1. Product introduction:

New multi-functional rescue boots, high-quality embossed leather, PU double-density wear-resistant outsole, special three-layer insole, comfortable and durable, safe and fashionable

2, product features:

Insole consists of three layers

level one:

The use of breathable sweat-absorbing mesh, compared with the traditional Canberra, has a good breathable sweat absorption function, and good wear resistance, greatly extending the life of the insole.

Second floor:

The use of high-molecular polyether materials fundamentally improves the weakness of the traditional insoles' stinky feet, and has good properties such as sweat absorption, odor absorption, and sterilization.

the third floor:

EVA punching is used to provide sufficient shock absorption to increase the comfort of wearing. The insoles made of polyether materials are the standard configuration of high-end fashionable leather shoes and sports shoes.

3, product parameters:

Help surface: high-quality embossed leather

Inside: High quality BK mesh, wear-resistant

Shoe tongue: sponge tongue, comfortable to wear

Neckline: Sponge lined collar, comfortable to wear

Shoelaces: High-strength nylon shoelaces

Shoe eye buckle: rust-proof copper buckle

Steel baotou: withstands impact of 200 Joules /15000 Newtons

Insole: made of polymer ether material, breathable, absorbs sweat, sterilizes, sucks and smells

Sole: PU double density outsole wear, non-slip, oil, heat
