BIS Certification for Resin Treated Compressed Wood Laminates Compregs General
Resin-treated laminates made from compressed wood, also known as Compregs, which are relatively new classes of engineered wood with excellent performance attributes, which have not only found market acceptance but are widely being used in various industries. These laminates involve the use of wood veneers or fibers of aspects bonded together with synthetic resins at high temperature and pressure and turns out to also be very strong and has a capability of resisting moisture and warping. In India, Quality Control Orders (QCOs) have been framed by the Bureau of Indian Standards (BIS) for compregs to conform to standard norms of safety and quality. The setting up of this kind of regulatory framework is important for the manufacturer's drive to offer quality goods to the consumers as well as protect end users. Moreover, in cases where composite materials are used as a solution for sustainable and high-performance demands as a material, it requires careful knowledge about the compregs manufacturing process, performance requirements, testing, and certification procedure.
In this blog, more information about the applications of resin-treated compressed wood laminates in the market, the reason behind BIS certification, and the compliance process involved in getting the same. Regardless of whether you are a manufacturer, a consumer, or an industry expert, this information-packed guide will prove helpful when it comes to understanding compregs.

Resin-treated compressed wood laminates (compregs)–For general purposes
Compregs are among the various wood products fabricated from layers of wood veneers or strands of fibers that have been bonded together with synthetic resins. This process improves the physical characteristics of the wood, the most notable being increased density making it more decay resistant, moisture resistant, and for use in a variety of uses. Compregs are especially prized for their high strength-to-weight ratio, low tendency to warp, and the fact that they can be easily integrated into a range of designs.
Manufacture of compregs involves putting these layers through high pressure and temperature in order to both cure the resin and ensure compregs density and strength. It is important for use in situations that may otherwise be vulnerable to rot, thanks to water or any other natural conditions or pressure from mechanical forces that are common in the industry.
Manufacturing Process
The manufacturing process of resin-treated compressed wood laminates consists of several key steps:
- Material Selection: Thick or thin, perfectly chosen veneers or fibers are procured from reliable sources. Their quality directly influences the properties of the final product and must meet defined specifications.
- Preparation: The raw wood is kiln-dried to achieve the optimal moisture content. This enhances the bonding capability between the wood and the resin.
- Resin Application: The dried wood layers are coated with thermosetting synthetic resins such as phenolic, urea-formaldehyde, or melamine-formaldehyde. The type of resin used greatly affects the final performance of the laminate.
- Layering: The resin-coated layers are aligned in specific orientations to improve strength and stability. Accurate alignment is key to ensuring uniform mechanical properties.
- Compression: The layered assembly is placed in a hydraulic press where it is subjected to high temperature and pressure. This not only bonds the layers but also cures the resin, forming a cohesive and durable structure.
- Cooling and Finishing: After pressing, the laminate (compreg) is gradually cooled to prevent warping. It is then cut into desired shapes and may undergo further finishing processes like sanding or re-coating to meet specific application needs.
This method yields a material that exhibits superior mechanical properties than traditional wood products.
Performance Requirement and Test Method
It is imperative that Compregs exhibit specific performance characteristics to be applied effectively in applications. Key performance indicators include:
- Mechanical Strength: It is required that the Compregs should have high tensile and compressive strength.
- Moisture Resistance: The material used should not be affected by swelling and degradative changes that occur when it is exposed to moisture.
- Dimensional Stability: Compregs should not undergo significant changes in their shape in response to fluctuations in environmental influences.
- Fire Resistance: If the application demands, there may be a need for fire retardant.
Testing Methods
Many of the testing methods applied to compregs are as per tests prescribed by some organizations of testing such as the Bureau of Indian Standards (BIS). Common testing methods include:
IS 1734 (Part 1):
This standard provides procedures for evaluating the physical characteristics of wood composites including compregs.
IS 3087:
This standard outlines procedures for determining the moisture content, and the floors’ ability to resist changes in dimension.
IS 5509:
This standard describes procedures for fire-resistant testing of building elements, products, and structures.
These standardized tests make sure that compregs meet necessary legal standards and are dependable in their sold uses.
Laboratory Requirements
To conduct testing on the Resin treated compressed wood laminates (compregs) - For general purposes effectively, laboratories must adhere to specific requirements:
- Equipment:should have state-of-art testing equipment like tensile testing machines, and spectrometers, ultrasonic testing gadgets.
- Qualified Personnel:Technicians have to understand and know additional testing techniques and protocols to conduct efficient tests.
- Quality Control Procedures: The applying organization should ensure quality assurance to enhance the reliability of the tested samples in laboratories.
Labeling and Marking Requirements
Labeling and markings are fundamental requirements of BIS standards regarding specifications for Resin-treated compressed wood laminates (compregs)– For general purposes. Each product must include:
- Manufacturer's Name or Trademark: In a manner that tells the consumer who produced it with clarity, means everything is right.
- ISI Mark: The ISI mark has to be affixed prominently on the product in case the product has been certified to conform to Indian standards.
- Material Information: Material should be mentioned along the labels that the footwear is made from and any other information concerning the safe usage of the product.
- Packaging Requirements: It is also important to label the packaging with the product type and care instructions so that the customers can maintain the product for the longest time.

BIS Certification Process
The BIS certification process for Resin treated compressed wood laminates (compregs) – For general purposes involves several steps:
Step 1: Application Submission
Applications are filled including relevant documents that outline the production processes of the manufacturers.
Step 2: Factory Inspection
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
Step 3: Product Testing
The samples from the production batches are analyzed at the BIS-accredited laboratories.
