Safety Hasp Specifications, Technical Requirements, Marking Requirements

Safety Hasp at the crucial time is to save lives a thing, so the production of Safety Hasp, the use of the relevant standards. What are the national standards for Safety Hasp? How long is the life of the helmet? What is the safety distance of the helmet national standard head and cap body?

Helmet national standard

Safety Safety Hasp are safety cap production specifications, technical requirements, marking requirements and inspection rules. Generally refers to the latest national standard GB2811-2007. This standard specifies the physical performance requirements, technical performance requirements and inspection rules, management, marking and packaging of Safety Hasp used in industry. Applicable to industrial Safety Hasp commonly used, and other special features added, it is only applicable to the corresponding special places.


Vertical spacing: measured according to the specified conditions, the value should be between 25-50mm. Horizontal spacing: measured according to the specified conditions, the value should be between 5-20mm. Wear height: measured according to the specified conditions, the value should be between 80-90mm. Cap hoop Size: divided into the following three numbers:

Trumpet: 51-56cm;

Medium: 57-60cm;

Large: 61-64cm;

5, weight: a complete helmet, the weight should be reduced as much as possible, should not exceed 400G.

6, hat size: minimum 10mm, maximum 35mm. Hat along the slope of 20 ° -60 ° is appropriate.

7, vent: Safety Hasp can be set on both sides of the vent hole.

8, cap: minimum 10mm, maximum 55mm.

9, color: helmet color is generally light or eye-catching color is appropriate, such as white, light yellow and so on.

basic requirements

Impact absorption performance: with three Safety Hasp were 50 ± 2 ℃ (mine with a helmet 40 ℃), - 10 ± 2 ℃ and immersion in three cases, and then use 5Kg steel hammer from the height of 1m drop test , The maximum impact of the head model of the maximum should not exceed 4900N.

Penetration resistance: According to the material of Safety Hasp selected 50 ± 2 ℃, -10 ± 2 ℃ and immersion in one of three methods for treatment, and then use 3KG steel cone from 1m height drop test, steel cone should not Head mold contact.

The helmet is to prevent the impact of damage to the head of the protective equipment. By the cap shell, cap lining, cheek band and the composition of the hoop. The shell is hemispherical, sturdy, smooth and has a certain degree of flexibility, the impact of impact and puncture kinetic energy mainly by the hat shell to bear. Between the cap shell and the cap lining to leave a certain space, can buffer, disperse the instantaneous impact force, so as to avoid or reduce the direct damage to the head. Impact suction performance, puncture resistance, lateral rigidity, electrical insulation, flame resistance is the basic technical performance of the helmet requirements.

other requirements

Low temperature performance: Where less than -10 ℃ helmet impact absorption performance and resistance to penetration to meet the requirements of 2.1.1 and 2.1.2.

Flammability: Combine the helmet with the flame and method specified in GB2812-2006 "helmet test method" for 10 seconds. After removing the flame, the cap shell flame should be free to destroy within 5 seconds.

Electrical insulation performance: AC 1200V pressure test 1 minute, the leakage current should not exceed 1.2mA.

Lateral rigidity: GB2812-2006 with the provisions of the method to the Safety Hasp by 43kg pressure, cap shell maximum deformation should not exceed 40mm, deformation after unloading should not exceed 15mm.

3, marking requirements

Each top helmet shall have the following three permanent marks: manufacturer name and trademark, model; manufacturing year, month; license number.

The safety Safety Hasp with other properties shall be marked on the hat as follows: A safety helmet that complies with the low temperature performance of 2.2.1 shall be marked with a low temperature temperature, such as "-20 ° C", "- 30 ° C"; 2.2.2 resistance to burning performance requirements of the Safety Hasp, made in the hat "R" mark; meet the 2.2.3 electrical insulation performance requirements of the helmet, made in the hat "D" mark;

D, meet the 2.2.4 lateral rigid requirements of the helmet, made in the hat "CG" mark.

testing regulations

Safety Hasp must be designated by the state supervision and inspection departments according to the standard identification, obtain a permit before the production. Each safety helmet is manufactured and must be inspected by the inspection department and factory inspection certificate. To 1000 ~ 20000 for the first batch. Safety Hasp in accordance with the provisions of GB2812 ~ 81 batch test, if not qualified, should take double product re-inspection. After the re-inspection there is still a non-qualified, then the helmet is unqualified. The designated technical inspection department of the State shall have the right to carry out the technical performance test from time to time. For those who do not follow the standard production, product technical performance can not meet the requirements of the enterprise, the right to make a warning or revoke the production license. The production license is changed every two years.

(Not including accessories); large Safety Hasp do not exceed 460g (not including accessories); cold hat does not exceed 690g (not including accessories).
