Industrial belts do not fail loudly. They fail quietly. A little heat. A little friction. Static you do not see. By the time something goes wrong, the damage is already done.

That is why fire-resistant and antistatic endless V-belts are treated differently under Indian law. BIS does not assume safety here. It demands proof. If your belt is meant for hazardous industrial use and falls under IS 2494 (Part 2): 1993, certification is not optional. It is expected.

This is not a marketing requirement. It is a safety rule.

What Makes These V-Belts Different?

An endless V-belt has no joint. It runs continuously. It does not get rest cycles. In heavy industries, these belts stay under load for hours, sometimes days.

Now place that belt inside a mine or a cement plant. Heat builds up. Dust collects. Static charge forms. A normal belt can spark. A spark is enough.

Fire-resistant and antistatic V-belts are built to reduce these risks. That is their only purpose. You will usually find them in:

  • Mines and underground operations
  • Cement and clinker units
  • Power generation facilities
  • Steel processing plants
  • Chemical handling environments

Because of where they are used, BIS treats them as risk-controlled products.

What Is IS 2494 (Part 2): 1993?

IS 2494 is the Indian Standard that applies to industrial V-belts.
Part 2 focuses only on belts that claim fire resistance and antistatic behaviour.

This standard does not test appearance or branding. It tests behaviour. How the belt reacts to flame. How it handles static charge. Whether it keeps its strength while doing both.

BIS uses this standard to answer one question:
 Is this belt safe to run where failure can cause damage?

Is ISI Mark Mandatory for These Belts?

Yes. There is no grey area.

If you manufacture, import, or sell these belts in India without an ISI mark, you are outside the law. BIS does not issue warnings first in most cases.

Possible outcomes include:

  • Goods being stopped or seized
  • Monetary penalties
  • Orders to withdraw products from sale
  • Action under the BIS Act

For safety-linked products, enforcement is active.

Who Must Apply for ISI Registration?

You must apply if you are involved at any of these levels:

  • You manufacture these belts in India
  • You manufacture abroad and export to India
  • You import and sell them under your name
  • You own the brand but outsource production

Foreign manufacturers must appoint an Authorized Indian Representative (AIR). BIS will not communicate without one.

Testing Requirements Under IS 2494 Part 2

Testing is not a formality here. BIS relies heavily on lab data.

Your product must be tested at a BIS-recognised laboratory. No exceptions. The lab checks whether the belt behaves the way the standard expects it to.

Testing usually covers:

  • Resistance to flame
  • Control of static electricity
  • Tensile strength
  • Elongation under load
  • Dimensional accuracy

If the sample fails, the application stops there.

Documents You Need to Prepare

BIS does not certify products in isolation. It certifies systems.

Have Questions? Let’s Talk. We’re Just One Click Away.

You will need to submit documents that show how your product is made, tested, and controlled. Typical requirements include:

  • Factory address and legal details
  • Manufacturing layout and machinery
  • Raw material information
  • Quality control steps
  • In-house testing capability
  • Lab test reports
  • AIR authorization, if applicable

During inspection BIS checks whether paperwork matches reality

How the ISI Registration Process Works (Step-by-Step)

This is how the process generally unfolds

Step 1: Product Confirmation

You first confirm that your belt is covered under IS 2494 (Part 2): 1993

Step 2: Application Submission.

You file the ISI application through the BIS system with product and factory details

Step 3: Sample Testing.

Samples are sent to a BIS-recognised lab. Testing is done strictly as per the standard

Step 4: Factory Inspection

A BIS officer visits your manufacturing unit. They look at machines, raw materials and testing setup

Step 5: Technical Review

BIS reviews the lab reports and inspection notes together.

Step 6: Licence Grant

If everything matches the standard, BIS issues the ISI licence.

Step 7: Surveillance

BIS may inspect again after certification. Compliance does not end with approval.

Validity and Renewal of ISI License

The licence is usually issued for one or two years.

Renewal is not automatic. BIS checks whether quality has been maintained. Sometimes fresh testing is required. Sometimes inspection happens again

If standards slip the licence can be suspended

Why ISI Certification Matters to You

In industrial supply chains, certification reduces questions.

  • Buyers trust certified belts
  • PSU and government tenders demand it
  • Safety audits become easier
  • Legal exposure is reduced
  • Product acceptance improves

In hazardous environments uncertified belts are often rejected outright

Common Issues That Cause Delays

Most delays are self-inflicted. Common reasons include:

  • Testing done at non-approved labs
  • Weak or incomplete documentation
  • No proper in-house testing setup
  • Difference between declared and actual process
  • Incorrect ISI marking use

These issues cost time.

Conclusion

If you deal with fire-resistant and antistatic endless V-belts, ISI certification under IS 2494 (Part 2): 1993 is not a choice. It is a requirement tied directly to safety and legality.
