Introduction | BIS for Safety Valves
In industries dealing with pressure systems such as oil & gas, chemicals, power plants, and manufacturing, safety is not optional—it is critical. Equipment operating under pressure can pose serious risks if not properly controlled. This is where safety devices like safety valves and bursting discs play a vital role.
To ensure these devices meet strict safety requirements, BIS for Safety Valves under IS 12370 (Part 3): 2023 has been introduced. This standard specifically focuses on safety valves and bursting disc devices used in combination, providing a structured approach to design, testing, and performance.
In this blog, we will explain everything you need to know about this certification in simple language, including its importance, process, benefits, and challenges.
What is BIS for Safety Valves IS 12370 (Part 3): 2023?
BIS for Safety Valves IS 12370 (Part 3): 2023 is an Indian standard that outlines the specifications required to be met when safety valves and bursting disc safety devices are installed together in a system.
The safety valve and bursting disc safety device combination is designed to provide maximum safety to equipment against excessive pressure through the following means:
- Release of pressure through the safety valve
- Provision of backup through the bursting disc safety device
- Maximum reliability in critical applications
The standard is harmonized with ISO 4126-3:2020, which implies that safety is being implemented according to globally accepted safety practices.
Key Coverage of the Standard
- Design specifications of the combination device
- Installation specifications
- Performance testing specifications
- Operating safety specifications
- Material specifications
Why is BIS for Safety Valves Required?
BIS for Safety Valves ensures that safety devices meet quality and safety standards before entering the market. Without proper certification, these devices may fail under pressure, leading to accidents or equipment damage.
Key Reasons
- Ensures compliance with Indian safety regulations
- Prevents industrial hazards and accidents
- Guarantees product reliability and durability
- Builds trust among customers and stakeholders
- Required for government tenders and approvals
Why Combined Devices Need Special Certification
Combined systems are more complex than standalone safety valves or bursting discs. Certification ensures:
- Proper coordination between both devices
- No interference in performance
- Accurate pressure release mechanisms
