BIS ISI Mark Registration for Asbestos – Cement Pipes and Fittings for Sewerage and Drainage IS 6908:1991

If you manufacture asbestos cement pipes or fittings used for sewerage and drainage you cannot ignore BIS certification. It is not optional. It is a statutory requirement when the product falls under mandatory certification

You are dealing with public infrastructure. These pipes carry wastewater. They operate underground. They face pressure, corrosion, and long service exposure. One weak batch can damage entire drainage systems. 

That is why the Bureau of Indian Standards (BIS) enforces compliance under IS 6908:1991

What Is IS 6908:1991 and Why Does It Matter?

The Bureau of Indian Standards is the national authority responsible for standardization and product certification in India. Under its certification scheme, specific products must comply with defined Indian Standards before sale

IS 6908:1991 covers:

• Asbestos cement pipes
• Asbestos cement fittings
• Products used in sewage systems
• Products used in drainage networks

The standard defines:

• Dimensions
• Physical properties
• Hydrostatic pressure requirements
• Crushing strength
• Water absorption limits
• Marking requirements

You must manufacture strictly according to this specification if you want the ISI Mark

Is BIS Certification Mandatory for IS 6908 Products?

Yes. If the product is notified under compulsory certification, you cannot sell it without an ISI license.

The requirement comes under the authority of the BIS Act 2016. Manufacturing without certification can result in:

• Seizure of goods
• Financial penalties
• Prosecution
• Cancellation of business credibility

Before applying, you must verify whether your exact product variant falls under mandatory notification

What Must You Prepare Before Applying?

Many manufacturers rush into the BIS portal without groundwork. That causes delays

You must first ensure:

1. Your factory has proper production facilities
2. You maintain documented quality control systems
3. In-house testing facilities are available as per IS 6908
4. Calibrated equipment is maintained with records
5. Technical staff are assigned for quality supervision.

BIS does not issue licenses based on paperwork alone. It verifies actual capability

Step-by-Step BIS ISI Registration Process

The certification process follows the Scheme-I (ISI Mark Scheme) of BIS

Step 1: Online Application

You must apply through the official BIS portal. The application includes:

• Factory details
• Product scope
• Manufacturing flowchart.
• Machinery list
• Test equipment list
• Quality control documents

Accuracy matters. Any mismatch during inspection creates objections

Step 2: Factory Inspection by BIS

After document scrutiny BIS assigns an inspecting officer

During inspection they will:

• Verify manufacturing process
• Review raw material controls
• Examine testing procedures
• Check calibration records
• Draw product samples

You cannot prepare overnight for this. Your systems must already be functioning

Step 3: Product Testing

Samples collected during inspection are sent to a BIS-recognized laboratory

Testing includes checks for:

• Crushing load
• Hydrostatic pressure
• Dimensional tolerance
• Water absorption
• Marking compliance

The product must meet all parameters of IS 6908:1991

Failure in even one major parameter may require re-sampling

Step 4: Grant of License

If inspection and test reports are satisfactory, BIS grants the license.

You receive:

• A CM/L number
• Permission to use the ISI Mark
• Defined scope of product and sizes

Only after a license grant can you mark your products with the ISI logo

Ongoing Compliance Is Not Optional

Many manufacturers assume that certification ends after the license grant. That is incorrect

BIS conducts:

• Surveillance inspections
• Market sampling
• Periodic factory audits

You must:

• Maintain production records
• Conduct routine in-house tests
• Preserve test data
• Renew the license before expiry

Non-compliance can lead to suspension

Common Mistakes You Should Avoid

From practical experience, these are common issues:

• Inadequate in-house testing setup
• Improper calibration documentation
• Poor raw material traceability
• Incorrect marking format
• Submitting incomplete application data

Each mistake increases processing time

Why Professional Guidance Makes a Difference

BIS certification involves technical interpretation. IS 6908 is not a simple document. It requires understanding of testing methodology and production control

This is where Agile Regulatory stands out

Agile Regulatory has experience in handling ISI certification projects across sectors. When you work with a structured consultant, you avoid guesswork

With professional support, you get:

• Correct documentation drafting
• Pre-inspection gap analysis
• Technical guidance on testing setup
• Application filing support
• Inspection coordination
• Post-license compliance support

Instead of reacting to objections, you move proactively.

Key Documents You Will Need

Prepare these in advance:

• Factory registration documents
• GST certificate
• Manufacturing layout
• Process flowchart
• List of machinery
• List of testing equipment
• Quality manual
• Calibration certificates
• Raw material test records

Organized documentation reduces objections.

Cost and Timeline Considerations

The timeline depends on:

• Factory readiness
• Test report results
• Inspection scheduling

Typically, it may take a few months from application to license grant if everything is in order.
Costs include:

• BIS application fees
• Inspection charges
• Testing fees
• Annual license fee

Exact amounts are published on the official BIS website.

Final Thoughts

If you manufacture asbestos cement pipes and fittings under IS 6908:1991, you cannot afford compliance gaps

BIS certification protects public infrastructure. It also protects your business credibility

Do not treat ISI Mark registration as a formality. Treat it as a structured compliance project

If you want the process handled professionally and without unnecessary delays Agile Regulatory can guide you from application to license grant and beyond

Take the right step early. It saves time, money and operational risk
