This standard specifies the materials, workmanship, finish, construction, and performance requirements for protective helmets (with or without lower face cover) used by two-wheeler riders on a daily basis. This standard's helmets are not intended for high-speed competitive events.

The standard specifies helmets in the sizes 500 mm, 520 mm, 540 mm, 560 mm, 570 mm, 580 mm, 600 mm, and 620 mm to match the head forms.

The following test shall be carried out to check the helmet's performance.

• Impact Absorption Test
• Resistance to penetration Test

• Dynamic Test of Retention System
• Audibility Test
• Retention Test of Helmet

Each helmet must be clearly and indelibly marked with the manufacturer's name or trademark, size, year of manufacture, and helmet mass. A standard mark (ISI Mark) may also be applied to the helmet. The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control and testing capabilities, and production process during a visit to manufacturing premises.
