Every retro-reflective device must have permanent markings indicating the part number of ISO 6742, along with the manufacturer's name or trademark. Products meeting the Indian Standard and covered by a license must display the Standard Mark (ISI Mark). Marking should adhere to the requirements outlined in IS 6742 (part 2): 2015. Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to utilize the standard mark (ISI Mark). This license is granted after a thorough assessment of manufacturing infrastructure, quality control, testing capabilities, and production processes.

This standard outlines the photometric and physical criteria for retro-reflective devices installed on bicycles intended for public road use. These retro-reflective devices play a crucial role in enhancing cyclist visibility during low-visibility conditions and at night, thus aiding in alerting all road users to the presence of cyclists.

Retro-reflective devices are categorized according to IS/ISO 6742-2:2015 based on Product Type and Color, as outlined below:

• Reflector

• Retro-reflective Tyres (White, White/Yellow)

• Retro-reflective Spokes (White)

• Retro-reflective Spoke Cases (White)

The reflector must satisfy the photometric and colorimetric criteria specified in the standard. CIL values for reflectors and retro-reflective tires should meet or exceed the standards outlined. Additionally, the reflector must feature a clearly defined preferred assembly method to ensure proper orientation when mounted on the bicycle.

For testing purposes, samples of each specific type of Retro-Reflective Device (Reflector, Retro-reflective Tyres, Retro-reflective Spokes, and Retro-reflective Spoke Cases) must be included.

TESTS

The subsequent test must be conducted for Retro-reflective devices.

• Temperature resistance test

• Colorimetric requirements

• Photometric requirements,

• Moisture Resistance test

• Resistance to fuels

• Impact test

• Adhesion

• Abrasion resistance

• Water test

• Resistance to corrosion

A properly maintained laboratory is required for conducting various tests in accordance with the methods outlined in the standard.
