- BIS Certification Asymmetrical Sheets ensures compliance with IS 14871:2000 for Fibre Reinforced Cement Products.
- The ISI mark confirms product strength, weather durability, and safety for roofing and cladding applications.
- Diligence Certification provides complete consulting support for testing, documentation, and BIS license approval.
Introduction
In early 2024, a building materials manufacturer in Pune faced a setback while bidding for a smart city roofing project. Their Fibre Reinforced Cement (FRC) asymmetrical section sheets were technically sound, but the tender committee rejected their offer — simply because the sheets lacked BIS Certification under IS 14871:2000.
Under the Bureau of Indian Standards (BIS) Act, 2016, roofing and cladding materials supplied for infrastructure and housing projects must bear the ISI Mark to ensure safety, durability, and compliance with Indian standards.
This case reflects a common challenge in India’s roofing industry — manufacturers meeting internal quality checks but missing the mandatory BIS license, which ultimately restricts market access.
At Diligence Certification, we guide manufacturers through the entire certification journey — from lab testing to final BIS license approval — ensuring full compliance with IS 14871:2000( bis certification asymmetrical sheets ) and zero rejection during audits.
Understanding IS 14871:2000 — The Standard Behind the Certification
IS 14871:2000( bis certification asymmetrical sheets ) lays down the specifications for Fibre Reinforced Cement Products – Long Corrugated or bis certification asymmetrical sheets.
These products are used extensively in industrial sheds, agricultural buildings, housing colonies, and institutional roofing, where durability and weather resistance are vital.
Key Technical Parameters Covered Under IS 14871:2000:
- Composition:
Sheets are made of cement reinforced with organic or inorganic fibres, providing enhanced tensile strength and flexibility. - Dimensional Accuracy:
The standard defines strict tolerances for thickness, width, and corrugation geometry for precise fitting during construction. - Mechanical Strength:
Minimum breaking load, bending strength, and impact resistance must meet the required BIS benchmarks. - Water Absorption:
Sheets are tested for moisture absorption to prevent degradation during monsoon or humid conditions. - Fire Resistance:
FRC sheets must withstand standard fire exposure without losing structural integrity. - Weather Durability:
Accelerated weathering tests are conducted to simulate years of outdoor exposure. - Marking Requirements:
Each BIS-certified product must display the ISI Mark, manufacturer’s name, batch number, and license number (CM/L).
Why BIS Certification for Roofing and Cladding Sheets is Crucial
1. Legal Requirement under BIS Act, 2016
Manufacturers cannot legally manufacture or sell asymmetrical section roofing sheets in India without a BIS license for IS 14871:2000.
Violations can lead to product seizure, penalties, or even factory closure.
2. Assurance of Quality and Performance
BIS testing ensures that roofing materials perform well under load-bearing, temperature, and environmental stress, meeting national safety benchmarks.
3. Acceptance in Public and Private Tenders
Government housing schemes like PMAY (Pradhan Mantri Awas Yojana) and Smart City projects strictly mandate ISI-marked roofing and cladding sheets.
4. Competitive Market Advantage
ISI-certified products build customer confidence, strengthen brand reputation, and open access to large infrastructure projects.
5. Export Readiness
Many importing countries accept BIS-certified Indian products as proof of compliance with global safety standards — a key advantage for exporters.
The ISI Mark Explained
The ISI mark on asymmetrical roofing and cladding sheets is not just a symbol — it’s a verified assurance that the product conforms to IS 14871:2000(bis certification asymmetrical sheets).
What the ISI Mark Confirms:
- The product has passed BIS-approved lab testing.
- The manufacturing process meets BIS factory audit requirements.
- Ongoing surveillance ensures consistent product quality.
- The factory maintains traceable production and quality control records.
Benefits of BIS Certification for Manufacturers
| Benefit | Description |
| Legal Compliance | Mandatory under BIS Act, 2016 for roofing sheets under IS 14871:2000(bis certification asymmetrical sheets) |
| Enhanced Durability | BIS-certified sheets undergo stringent physical, mechanical, and fire tests |
| Market Recognition | ISI mark improves acceptance among architects and builders |
| Tender Eligibility | Required for government and institutional projects |
| Customer Confidence | Buyers prefer certified materials for safety assurance |
| Export Leverage | Recognized proof of quality for international markets |
Eligibility Criteria for BIS Certification
To obtain the license, a manufacturer must:
- Be a registered business entity (Company, LLP, or Proprietorship).
- Operate a functional plant for Fibre Reinforced Cement sheets.
- Have in-house quality testing facilities.
- Employ technically qualified personnel.
- Permit BIS inspectors for audit and sample collection.
Step-by-Step Process of BIS Certification for Asymmetrical Roofing Sheets
1. Identify Applicable Standard
Confirm that your product falls under IS 14871:2000( bis certification asymmetrical sheets ) – Fibre Reinforced Cement Products.
2. Application Submission
Submit an online application on the Manak Online BIS Portal with factory and product details.
3. Product Testing
Send samples to a BIS-recognized laboratory for testing on strength, dimensional accuracy, and weather resistance.
4. Factory Inspection
BIS officers visit the facility to verify production process, machinery, and quality control system.
5. Review and Grant of License
After successful lab results and inspection clearance, BIS grants the ISI license, authorizing use of the ISI mark.
6. License Validity and Renewal
The license is valid for 2 years, renewable for up to 5 years based on consistent compliance.
Documents Required for BIS Certification
| Category | Documents |
| Company Information | Incorporation Certificate, GST, Udyam Registration |
| Factory Details | Layout Plan, Machinery List, Process Flow Diagram |
| Quality Records | Internal QC Reports, Calibration Certificates |
| Product Data | Raw Material Composition, Test Results, Fire Resistance Proof |
| BIS Lab Report | Results from BIS-recognized testing laboratory |
Common Challenges During BIS Certification
- Test Rejection:
Failing water absorption or bending strength tests due to improper curing or fibre ratio. - Incomplete Documentation:
Missing quality control logs or calibration certificates often delay approval. - Factory Readiness Issues:
Lack of standard curing chambers or mixing consistency can cause inspection failures. - Testing Delays:
BIS-approved labs may have long queues, affecting project timelines. - Consultant Mistakes:
Using inexperienced agents can result in incomplete test submissions or wrong application categories.
At Diligence Certification, we pre-audit every client’s facility to fix non-conformities before BIS inspection — reducing rejection chances to near zero.
