BIS Certification for Valve Fittings for SCBA and SCUBA IS 7302:2018

Valve Fittings For Gas Cylinder Valves For Use With Breathing Apparatus

BIS certification for Valve fittings for Self-Contained Breathing Apparatus (SCBA) and Self-Contained Underwater Breathing Apparatus (SCUBA) is are crucial component ensuring safe and reliable breathing gas delivery. These fittings must be robust, high-pressure capable, and resistant to corrosion, wear, and damage. In India, compliance with IS 7302:2018 and BIS ISI certification is mandatory for these fittings. This standard outlines the requirements and testing procedures for valve fittings used in SCBA and SCUBA systems to ensure reliability, durability, and safety under extreme conditions.

Overview of IS 7302:2018

IS 7302:2018, titled “Valves for Self-Contained Breathing Apparatus and Self-Contained Underwater Breathing Apparatus – Specification”, provides comprehensive guidelines covering:

● Design and construction requirements

● Material specifications (including corrosion resistance and strength)

● Thread types (including taper and parallel threads)

● Performance under simulated real-world conditions

● Compatibility with breathing gas mixtures (air, oxygen, oxygen/nitrogen)

The standard applies to valve fittings intended for breathable gases and ensures that the valves meet the stringent requirements needed for critical-use applications. Whether used on land in hazardous environments or underwater during dives, these valves must perform without fail.

Mandatory BIS Certification

As per the Quality Control Orders (QCOs) issued by the Indian government, manufacturers of valve fittings for SCBA and SCUBA must obtain BIS ISI certification under IS 7302:2018 to legally sell or distribute these components in India.

This certification ensures:

● Regulatory compliance

● Assurance of safety and performance

● Eligibility for tenders and supply contracts

● Market credibility and customer trust

For importers and OEMs, sourcing BIS-certified valve fittings is not only mandatory but also a critical risk mitigation step.

Key Requirements and Features of IS 7302:2018

The standard lays out specific requirements for the mechanical design, material quality, and safety features of valve fittings. This includes:

● Material selection: Typically high-grade metals such as brass, stainless steel, or aluminum alloys that meet defined chemical compositions and mechanical properties.

● Protective finishes: To resist corrosion in chemically aggressive or humid environments.

● Thread types and sealing: Ensures secure fitting between the cylinder and breathing device without leaks.

● Safety devices: May include pressure relief features or mechanisms to prevent accidental opening.

Every design element is evaluated for functionality under various scenarios, ensuring that the final product is robust enough for emergency use.

Tests Conducted for BIS Certification

To comply with IS 7302:2018, manufacturers must subject valve fittings to a comprehensive suite of mechanical, chemical, and performance tests. These include:

● Chemical Composition Test: Verifies the material makeup of the valve body to ensure durability and corrosion resistance.

● Tensile Strength and Elongation Tests: Ensures the metal can withstand high pressure without deformation.

● Impact Strength Test: Evaluates resistance to mechanical shocks, simulating drops or collisions during use.

● Valve Burst Pressure Test: Assesses the maximum pressure the valve can handle before failure.

● Valving Torque Test: Measures the amount of torque required to open and close the valve, ensuring usability in emergencies.

● Leak Tightness Test: Ensures zero gas leakage under pressure.

● Endurance Test: Verifies performance over extended cycles of opening and closing.

●Flame Impingement Test: Ensures the valve can withstand exposure to flame in fire rescue environments.

●Environmental Stress and Finish Tests: Evaluates corrosion resistance, protective coatings, and performance under adverse environmental conditions.

All tests are carried out under controlled laboratory conditions at BIS-recognized testing facilities.

Certification Process for Manufacturers

To obtain BIS certification for SCBA/SCUBA valve fittings:

Application Submission: Manufacturers submit detailed specifications and safety information for the valve fittings.

Document Review: BIS assesses the documentation to verify adherence to IS 7302 standards.

Factory Inspection: BIS conducts an on-site inspection to review production and quality control processes.

Sample Testing: Samples are tested in BIS-recognized labs to ensure they meet the requirements of IS 7302 for performance and safety.

Certification Approval: Upon successful inspection and testing, BIS grants certification, allowing the use of the ISI mark on the fittings.

Why BIS Certification is Critical

Valve fittings for SCBA and SCUBA are used in high-stakes environments—fires, deep-sea dives, confined space rescues, and industrial disaster zones. BIS certification:

● Protects users from equipment failure during critical operations

● Helps organizations and governments ensure safety and reliability of gear

● Builds confidence among procurement agencies, firefighters, defense personnel, and divers

● Enables entry into regulated markets with full compliance

Conclusion

The safety, performance, and dependability of valve fittings in SCBA and SCUBA systems are non-negotiable. With IS 7302:2018, the Bureau of Indian Standards ensures that every certified valve fitting meets strict engineering and safety criteria. For manufacturers, achieving BIS certification is not just a regulatory requirement—it’s a commitment to saving lives through dependable engineering.

If you are a manufacturer, importer, or distributor of SCBA/SCUBA valve fittings in India, BIS certification under IS 7302:2018 is essential to your product’s legality and marketability.
