Introduction
Resin treated compressed wood is advanced engineered materials that are extensively used in electrical, industrial, and structural applications. These materials are made from wood veneers being compressed together and impregnated with synthetic resin under controlled temperature and pressure. It has high mechanical strength, electrical resistance, and durability.
BIS has made it mandatory to get BIS Certification for Resin Treated Compressed Wood under IS 3513:1989 in the interest of safety, reliability, and standardization. This certification is a confirmation that the product meets the Indian Standards and is therefore safe for use, both in a industrial application and for consumers as well.
What is BIS Certification for Resin Treated Compressed Wood?
BIS certification for Resin Treated Compressed Wood is a mark of assurance of quality issued by the Bureau of Indian Standards and conforms to IS 3513:1989.

Resin Treated Compressed Wood vs Plywood
More uniform and moisture-resistant than plywood, though plywood still wins in flexibility or curved applications.
| Feature | Resin Treated Wood | Marine Plywood |
|---|---|---|
| Moisture swelling | < 5% | 10–15% |
| Density uniformity | High | Variable |
| Price per sq ft | Moderate | Higher |
Plywood suits curved designs because of its veneer layers, while resin boards are better for flat, load-bearing surfaces.
Scheme of Inspection and Testing (SIT)
The Scheme of Inspection and Testing (SIT) is an essential procedure under BIS certificate that ensures that resin-treated compressed wood laminates meet IS 3513:1989 specifications.
The key points of SIT are:
- Raw Material Inspection- Checking of wood and resin quality before the processing.
- In-Process Control- Continuom monitoring of lamination, compression, and curing. Finished Product Testing-Mandatory tests on finished products for compliance.
- Batch Sampling- Random samples selected for in-depth testing.
- Marking and Labeling- Batch should be marked as per BIS rules.
- Factory Inspection- Periodic visits of BIS officials for checking against standards.
Scope of the Licence
The scope of BIS certificate includes:
- Manufacturing and Quality Control Processes – Standardized production and quality assurance practices.
- Types of Compregs Based on Application – Electrical, chemical, or general purposes.
- Testing and Inspection Requirements – Major means to verify compliance with given performance and safety criteria.
- Marking and Labelling Requirements – Guidelines related to the application of the ISI mark and mandatory labelling requirements of the product.
