BIS Scheme X certification for Heat Treatment Equipment

The industrial world heavily depends on thermal processing machinery—equipment that modifies materials through heating, cooling, or both—to shape, harden, dry, melt, or sterilize them. From metallurgy and ceramics to chemicals and food processing, these machines are the backbone of high-precision, temperature-driven applications.

Recognizing the critical role of such equipment in safety, quality, and energy efficiency, the Government of India has made BIS Certification mandatory for all types of machinery for the treatment of material by a process involving a change of temperature and/or their assemblies, sub-assemblies, and components.

This mandate is part of the BIS Scheme X Certification, introduced by the Bureau of Indian Standards (BIS) under the Omnibus Technical Regulation Order, 2024, and is enforceable by 28th August 2025.

Let’s explore everything manufacturers and stakeholders need to know about BIS certification for heat treatment equipment, why it matters, and how to comply before the deadline.

Understanding Thermal Processing Machinery

Thermal processing machineryincludes a wide variety of equipment used to treat materials by altering their temperature. This can involve:

• Heating(e.g., furnaces, ovens, heaters, incinerators)
• Cooling(e.g., chillers, cryogenic systems)
• Drying(e.g., kilns, industrial dryers)
• Melting or hardening(e.g., induction furnaces, annealing machines)
• Sterilization or pasteurization(used in food, pharma, medical)

Heat exchangers and related systems

Such machinery is integral to manufacturing in sectors like:

• Metallurgy
• Ceramics and glass
• Petrochemical and refinery
• Pharmaceuticals and food processing
• Automotive and aerospace
• Textiles and paper

These machines typically operate under extreme thermal conditions. Poor design, manufacturing defects, or substandard components can lead tosafety hazards, energy inefficiencies, and environmental risks.

What is BIS Certification and Scheme X?

The Bureau of Indian Standards (BIS) is the national standards body of India, operating under the Ministry of Consumer Affairs, Food and Public Distribution. BIS formulates Indian Standards and regulates the quality and safety of products across industries.

BIS Scheme X Certification is a regulatory framework introduced on 16th March 2022, specifically for machinery and electrical equipment. It is governed by the BIS Conformity Assessment Regulations, 2018, and mandates:

• Conformance to relevant Indian Standards
• Product and factory inspection
• Testing in BIS-approved labs
• Grant of license to use the ISI mark

This scheme is particularly crucial for industrial machinery such as heat treatment and thermal processing equipment.

Omnibus Technical Regulation Order, 2024

To strengthen industrial safety and performance standards, the Ministry of Heavy Industries issued the Omnibus Technical Regulation Order, 2024. This order mandates that all types of machinery for the treatment of material by a process involving a change of temperature and/or their assemblies/sub-assemblies/components must be BIS certified under Scheme X by 28th August 2025.

This regulation applies to both domestic and foreign manufacturers, making it illegal to manufacture, import, sell, or distribute uncertified thermal processing machinery after the deadline. The mandate applies equally to foreign manufacturers exporting heat treatment or thermal processing machinery to India. Failure to comply by 28th August 2025 will result in import restrictions, rejection at customs, and legal penalties under the BIS Act, 2016.

Scope of BIS Certification for Thermal Processing Equipment

The following categories fall under the purview of BIS Scheme X certification for thermal processing equipment:

Complete Machines

• Industrial furnaces (electric, gas, oil-fired)
• Heat treatment ovens and kilns
• Tempering and annealing machines
• Refrigeration and cooling equipment
• Boilers (within defined pressure ranges)

Assemblies and Sub-Assemblies

• Heating coils, burners, and thermocouples
• Temperature control panels and units
• Heat exchanger assemblies
• Cooling compressors and chillers
• Gas/air distribution systems

Components

• Sensors, actuators, and insulation materials
• Pressure regulators, thermostats
• Safety valves, expansion tanks
• Structural enclosures and casings

Whether a standalone product or a part of a system, each unit must conform to Indian Standards applicable to its function and safety parameters.

BIS Scheme X Certification Process

Achieving compliance may seem daunting, but the process is fairly structured:

• Identify Relevant Standards:Determine the Indian Standards applicable to your specific product type.
• Product Testing:Samples must be tested in BIS-recognized laboratories. Tests include performance, safety, and endurance checks.
• Factory Inspection:BIS officials will inspect manufacturing units to assess quality control procedures, machinery, and adherence to production standards.
• Documentation:Submit all necessary documents, including technical specifications, quality manuals, test reports, and application forms.
• Grant of License:Once verified, BIS issues a license allowing the use of the Standard Mark under Scheme X.
• Surveillance and Renewal:The license must be renewed periodically, with follow-up inspections and tests to ensure continued compliance.

Conclusion

Thermal processing machinery plays a crucial role in industrial growth, but with that role comes a significant responsibility for safety, efficiency, and standardization. The BIS Scheme X certification for heat treatment equipment is not just a regulatory requirement—it is a vital step toward building trust, improving quality, and ensuring the safety of operations across sectors.

Whether you're a domestic producer or an international supplier, ensuring your thermal processing machines, assemblies, and components are BIS-certified will be key to sustaining and growing your market presence in India.
