The Bureau of Indian Standards has developed IS 9453:2014 for valve caps fitted to tube valves of automotive tyres. Though modest in size, these parts safeguard the valve from dust, contaminants, and moisture, thereby upholding consistent tyre pressure and prolonging the valve’s operational life. The specification stipulates criteria for material composition, design geometry, dimensional tolerances, and endurance testing to guarantee secure sealing and sustained performance. Suppliers wishing to market valve caps in India are required to secure BIS Certification. Only products meeting this certification may display the ISI mark, which signals conformity to Indian quality benchmarks and reliability for automotive service.
