Standard NIJ-0101.06

The NIJ-0101.06 standard is one of the most recognized and important standards for ballistic helmets. It sets requirements for the ballistic resistance of helmets and covers impact and penetration tests, which are investigated using different types of bullets

Helmet testing uses Magnum SJHP at 436 m/s and 357 SIG FMJ FN at 448 m/s

Kevlar helmets that comply with the NIJ-0101.06 standard are reliable and effective means of protection. The use of aramid fibers in the manufacture of helmets provides a high level of ballistic resistance, which is necessary for protection against various types of pistol bullets

The NIJ-0101.06 standard sets clear requirements for the thickness and weight of a helmet, as well as the level of protection it must provide. According to this standard, protection class IIIA corresponds to the highest level of protection against pistol bullets and the lowest level of protection against bullets from automatic weapons.

In addition, the NIJ-0101.06 standard establishes requirements for testing andundefined certification of helmets, which ensures high quality and reliability of the product. All tests are carried out under certain conditions, which include a shooting distance of 5 meters, an angle of inclination and a muzzle velocity. The test results are documented and analyzed to confirm the helmet’s compliance with the standard.

Therefore, aramid fiber helmets that comply with the NIJ-0101.06 standard are reliable and high quality. 

State standard of Ukraine DSTU 8835:2019, 1st class of protection

According to the State Standard of Ukraine DSTU 8835:2019 “Means of individual protection against ballistic impacts. Classification and general technical requirements”, it can be said that ballistic helmets of protection class 1 meet the following criteria:

1. Class of protection: Class 1 ballistic helmets are designed to protect against ballistic threats corresponding to 9 x 18 mm cartridges 9 mm Makarov at a velocity of 335 m/s and 9 x 19 mm LUGER pistol cartridge at a speed of 358 m/s

2. Tests: Class 1 ballistic helmets must pass the following tests:

tests for non-puncture and shape retention under the influence of temperatures from -20 °C to +50 °C;

tests for preservation of protective properties after exposure to moisture, heat and other atmospheric factors;

3. Protective properties: Class 1 ballistic helmets must provide protection against a direct hit by a bullet with a 9 x 18 mm cartridge, a 9 mm Makarov cartridge at a velocity of 335 m/s and a 9 x 19 mm LUGER pistol cartridge at a speed of 358 m/s from a distance of 5 meters.

So, if the helmetundefined meets all these requirements, then it can be assigned to protection class 1 in accordance with DSTU 8835:2019. undefined

State standard of Ukraine DSTU 8835:2019, 2nd class of protection

According to the State Standard of Ukraine DSTU 8835:2019 “Means of individual protection against ballistic impacts. Classification and general technical requirements”, ballistic helmets of protection class 2 must meet the following requirements:

1. Class of protection: Class 2 ballistic helmets are designed to protect against ballistic threats corresponding to 7.62 x 21 mm cartridges 7.62 mm Tokarev with a steel core at a speed of 430 m/s

2. Tests: class 2 ballistic helmets must pass the following tests:

shape retention test under the influence of temperature from -20 °C to +50 °C;

tests for preservation of protective properties after exposure to moisture, heat and other atmospheric factors;

3. Protective properties: Class 2 ballistic helmets must provide protection against a direct hit by a bullet from a 7.62 x 21 mm 7.62 mm Tokarev cartridge with a steel core at a speed of 430 m/s from a distance of 5 meters.

Therefore, if the helmet meets all these requirements, it can be classified as protection class 2, respectivelyundefined to DSTU 8835:2019. 

STANAG 2920

STANAG 2920 also provides for the testing of ballistic helmets. They are performed using a method similar to testing bulletproof vests. However, since helmets are designed to protect the head, they have their own requirements and regulations.

For testing helmets, special tools are used – anvils and bullet simulators, which are specially designed for ballistic head protection tests. The test involves firing a bullet at a helmet, which is fixed on a dummy head, and measuring the maximum level of deformation of the helmet.

The results of helmet tests are expressed in such indicators as “Ballistic Limitation Threshold” (BLT) and “Ballistic Resistance Limit” (BRL). BLT is defined as the minimum level of ballistic protection required to protect against a single shot, while BRL is defined as the maximum number of shots a helmet can withstand without losing its protectiveundefined properties.

STANAG 2920 allows you to test helmets both with the use of a single bullet-simulator and with the use of a consecutive series of shots to determine the limit of ballistic resistance. This allows you to set the maximum level of protection that a ballistic helmet can provide.
