- IS 3513( Part 3) applies specifically to general- purpose Compreg laminates used in structural and artificial operations.
- BIS instrument is obligatory for manufacturers dealing in Compregs in the Indian request.
- The standard focuses on mechanical strength, humidity resistance, and dimensional stability.
- Non-compliance can lead to request restrictions, seizures, and fiscal penalties.
- Working with an educated adviser significantly reduces blessing time and crimes.
Introduction | BIS for Compreg Wood Laminates
Resin treated compressed wood laminates generally known as Compregs — sit in a unique space between engineered wood and high- performance artificial material. They’re used where ordinary plywood fails electrical panels, cargo- bearing sequestration, wiles, institutions, and heavy- duty structural factors. Because these laminates are exposed to pressure, humidity, heat, and mechanical stress, quality thickness isnon-negotiable.
That’s where the Bureau of Indian Standards way in. Under IS 3513( Part 3), BIS lays down precise specialized and performance conditions to insure Compregs vended in India meet minimal safety and continuity marks.
What Are Resin Treated Compressed Wood Laminates (Compregs)?
Compregs are manufactured by macerating wood veneers or fabrics with thermosetting resins generally phenolic and compressing them under high heat and pressure. The result is a thick, rigid laminate with superior mechanical and electrical parcels compared to conventional wood products.
- High viscosity and compressive strength
- Excellent resistance to humidity and chemicals
- Stable confines indeed under cargo
- Good electrical sequestration parcels
- Long service life in demanding surroundings
IS 3513( Part 3) specifically covers general- purpose Compregs, distinguishing them from technical electrical or ornamental grades.
Why BIS Certification Is Required
The BIS for Compreg Wood Laminates instrument under IS 3513( Part 3) exists for practical reasons, not bureaucracy.
- Compregs are frequently used in cargo- bearing or safety-critical surroundings
- Poor- quality laminates can fail quietly, causing long- term structural damage
- Buyers — especially PSUs and EPC contractors — demand pukka material
- Instrument standardizes quality across domestic and imported products
- It protects manufacturers from liability linked to material failure
Importance and Benefits
| Importance | Benefits |
| Legal market entry | Unrestricted sale across India |
| Quality standardization | Fewer rejections and disputes |
| Buyer confidence | Easier approvals from OEMs & PSUs |
| Safety assurance | Reduced failure and warranty claims |
| Competitive differentiation | Stronger brand credibility |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Collect required technical documents
- Prepare product specifications
- Gather company registration details
- Ensure documents follow BIS format
Step2:Product Testing
- Send samples to a BIS-approved lab
- Conduct safety and quality tests
- Receive test reports
- Confirm compliance with BIS standards
Step3:Application Submission
- Fill out the BIS application form
- Upload all required documents
- Attach valid test reports
- Pay the necessary BIS fees
Step4:Scrutiny and Inspection
- BIS reviews submitted documents
- Authority verifies test results
- Factory/product inspection may occur
- Clarifications requested if needed
Step5:Grant of License
- BIS approves the application
- License number is issued
- Product can carry BIS mark
- Renewal required before expiry
Documents Required for BIS Certification
| Category | Documents Required |
| Business Documents | Business license/registration, ISO certificate, organizational details |
| Manufacturer Details | Factory layout, process flow chart, machinery list, production details |
| Product Documents | Product specifications, component list, user manual, model details |
| Testing Documents | Test report from BIS-recognized lab, sample details, test request form |
| Legal & Compliance | Authorization letter, brand ownership proof, trademark certificate (if any) |
| Import/Foreign Manufacturer (If applicable) | AIR (Authorized Indian Representative) details, contract agreement, overseas manufacturer documents |
Timelines, Costs, Validity & Renewal
- Timelines: Usually from 20 to 30 days, with only 7-15 days for the testing.
- Costs: The cost of the government and the test varies depending on the product. There can be some additional charges though.
- Validity: The validity period is 2 years in most situations.
- Renewal: The renewal is done before the expiration; there should be updated documents/tests; the renewal
Challenges of Obtaining BIS Certification Without a Consultant
On paper, the BIS instrument looks straightforward. In practice, numerous manufacturers struggle without professional support.
- Incorrect product slice and test lot selection
- Detainments due to deficient plant attestation
- Non-conforming internal quality control systems
- Repeated queries from BIS officers causing timeline overruns
One small mistake — like using the wrong resin specification or missing a test record — can reset the entire process.
Why Choose Diligence Certification Consultancy
Diligence Certification instrument is n’t just a paperwork tutor. The value lies in process clarity and threat reduction.
- Deep familiarity with wood laminate and resin- grounded product norms
- Pre-audit assessment to identify gaps before BIS examination
- End- to- end handling operation, testing collaboration, plant inspection
- Clear communication with BIS authorities on specialized interpretations
- Faster reversal with smaller compliance circles
For manufacturers concentrated on products and deals, outsourcing instrument to specialists avoids expensive distractions.
Who Needs This Certification?
- Indian manufacturers of Compreg laminates
- Importers selling Compregs under their brand in India
- OEM suppliers to infrastructure, power, and industrial projects
- Exporters planning domestic distribution alongside exports
If Compregs are part of your product line, IS 3513 (Part 3) is not optional.
Conclusion
BIS for Compreg Wood Laminates under IS 3513( Part 3) is lower about compliance and further about credibility. It confirms that a product designed to handle stress, humidity, and cargo can actually do so — constantly and safely.
Manufacturers who approach instrument strategically gain further than blessing. They gain smoother buyer onboarding, smaller specialized expostulations, and long- term brand trust. With the right guidance, the process becomes predictable rather of painful.
