BIS Scheme X Certification for Heat Treatment Equipment: A Complete Guide

 

Introduction

Heat treatment equipment plays a vital role in industries such as automotive, aerospace, construction, metallurgy, and manufacturing. Whether it’s furnaces, ovens, induction heaters, or quenching systems, these machines are critical for improving material properties like strength, durability, and hardness.

To ensure safety, quality, and compliance with Indian standards, the Bureau of Indian Standards (BIS) mandates Scheme X Certification for certain categories of heat treatment equipment. Manufacturers—whether domestic or international—must obtain this certification before selling their products in India.

In this blog, we will cover everything you need to know about BIS Scheme X certification for heat treatment equipment, including eligibility, process, documents, benefits, and compliance requirements.

What is BIS Scheme X Certification?

The BIS (Bureau of Indian Standards) operates certification schemes under the BIS Act, 2016 to regulate product quality in India.

Scheme X specifically covers products that fall under Compulsory Registration Order (CRO) or Mandatory BIS Certification. Heat treatment equipment, being high-risk machinery that involves high temperatures, energy consumption, and worker safety, is included in this category.

Once certified, manufacturers can use the ISI Mark, which acts as proof that the equipment complies with relevant Indian Standards (IS).

Why is BIS Certification Important for Heat Treatment Equipment?

Heat treatment equipment operates at high temperatures and directly impacts product quality and operator safety. Non-standard machines can lead to accidents, energy wastage, and poor-quality output. BIS certification ensures:

  • ✅ Safety Compliance – Reduces risks of fire, explosion, or equipment failure.

  • ✅ Product Quality – Guarantees machines meet Indian performance standards.

  • ✅ Legal Requirement – Mandatory for manufacturing, import, and sales in India.

  • ✅ Market Acceptance – Certified products gain easier access to industries, tenders, and exports.

  • ✅ Brand Reputation – ISI mark boosts credibility and customer trust.

Types of Heat Treatment Equipment Covered Under BIS

BIS Scheme X generally applies to the following heat treatment machines:

  1. Industrial Furnaces & Kilns – For heating metals, ceramics, or alloys.

  2. Heat Treatment Ovens – Used in hardening, annealing, and tempering processes.

  3. Induction Heating Systems – High-frequency heating for precision applications.

  4. Quenching Systems – Used for rapid cooling of metals.

  5. Carburizing & Nitriding Equipment – For surface hardening of steel components.

Each type of equipment is tested against relevant Indian Standards (IS codes) before certification.

Applicable Indian Standards

Some common IS Standards relevant to heat treatment equipment include:

  • IS 14700 – Safety of industrial furnaces and associated equipment.

  • IS 4159 – Heat treatment of steel products.

  • IS 1239 / IS 1248 – Guidelines for heating elements and thermal systems.

  • IS 302-1 – General safety requirements for electrical heating equipment.

(Exact standards depend on the type of equipment and application.)

Who Needs BIS Certification?

  • Domestic Manufacturers – Companies producing heat treatment equipment in India.

  • Foreign Manufacturers – Companies exporting heat treatment machinery to India (must appoint an Authorized Indian Representative - AIR).

  • Suppliers/Importers – Can only sell products in India if certified.

Step-by-Step Process of BIS Scheme X Certification for Heat Treatment Equipment

Step 1: Identify Applicable Standards

Determine which IS Standard applies to your equipment. For example, industrial furnaces may fall under IS 14700.

Step 2: Application Submission

Submit the BIS application online with required details such as:

  • Product type and model

  • Technical specifications

  • Manufacturer details

  • Factory location

Step 3: Product Testing

Samples of the equipment are tested in BIS-recognized laboratories to check compliance with:

  • Performance standards

  • Safety parameters

  • Energy efficiency

Step 4: Factory Inspection

BIS officials may inspect the manufacturing facility to verify:

  • Production capability

  • Quality control measures

  • Testing equipment availability

Step 5: Certification Grant

If all criteria are met, BIS issues a license under Scheme X. The manufacturer can then affix the ISI Mark on certified equipment.

Documents Required for BIS Certification

To obtain certification, manufacturers must submit:

  • Application form

  • Factory license & incorporation documents

  • Authorized Indian Representative (for foreign firms)

  • Test reports from BIS-approved labs

  • Quality Control Manual (QCM)

  • List of raw materials & suppliers

  • Manufacturing process flowchart

  • Trademark registration certificate (if any)

Timeline & Cost

  • Timeline – Usually 60–120 days, depending on testing complexity and documentation readiness.

  • Cost – Includes BIS application fees, sample testing charges, inspection expenses, and license fees. Costs vary based on equipment size, type, and testing requirements.

Benefits of BIS Certification for Heat Treatment Equipment Manufacturers

  1. Regulatory Compliance – Mandatory approval to operate in India.

  2. Customer Trust – ISI mark builds buyer confidence.

  3. Competitive Advantage – Preference in government and industrial procurement.

  4. Reduced Liability – Minimizes risks of accidents or product failures.

  5. Export Growth – Enhances acceptance in global markets.

Consequences of Non-Compliance

Manufacturers or importers selling uncertified heat treatment equipment may face:

  • Heavy penalties and fines.

  • Seizure of goods by authorities.

  • Ban on imports/manufacturing of non-compliant products.

  • Reputation damage in the market.

How to Ensure a Smooth Certification Process?

  • Engage an experienced BIS consultant for application and testing support.

  • Conduct pre-testing of equipment to avoid failures.

  • Maintain a strong in-house quality control system.

  • Stay updated with latest BIS notifications.

Conclusion

The BIS Scheme X Certification for Heat Treatment Equipment is a mandatory compliance requirement that ensures safety, performance, and quality in industrial applications. Whether you manufacture or import furnaces, ovens, or quenching systems, BIS certification allows you to legally sell products in India while building trust with industries and end-users.

With increasing emphasis on worker safety, energy efficiency, and product quality, obtaining BIS certification is not just a legal step—it’s a strategic move for long-term growth and brand recognition.

By preparing the right documents, testing equipment, and following BIS guidelines, manufacturers can smoothly obtain certification and proudly display the ISI Mark as a symbol of quality and compliance.
