Resin Treated Compressed Wood Laminates, commonly known as Compregs<\/strong>, are engineered wood-based materials manufactured using thin wood veneers and thermosetting synthetic resins. Through resin treatment, bonding, heat and pressure, the material obtains improved mechanical strength, dimensional stability, moisture resistance, machinability and resistance to certain corrosive agents and termite attack.<\/p>\n IS 3513 (Part 3):1989<\/strong> specifies requirements for Resin Treated Compressed Wood Laminates (Compregs) for General Purposes<\/strong>. The standard covers requirements relating to raw materials, manufacture, grades, types, dimensions, physical properties and mechanical properties.<\/p>\n Compregs manufactured for general engineering, textile and jute industry applications and other covered uses may fall within this standard. BIS currently lists IS 3513 (Part 3):1989 in its product manuals, and the applicable regulatory framework places resin-treated compressed wood laminates under mandatory compliance.<\/p>\n Compregs are manufactured from thin layers of wood veneer that are treated or combined with synthetic resin and subsequently bonded and densified under controlled heat and pressure.<\/p>\n Unlike ordinary solid wood, Compregs can provide improved:<\/p>\n They can be manufactured in different forms such as:<\/p>\n The BIS description specifically identifies applications in general engineering, textile industry, jute industry and certain specialised installations.<\/p>\n IS 3513 (Part 3):1989<\/strong> is the Indian Standard titled:<\/p>\n Specification for Resin Treated Compressed Wood Laminates (Compregs) \u2013 Part 3: For General Purposes<\/strong><\/p>\n It is the first revision<\/strong> of the standard. BIS’s Product Manual identifies it as the applicable standard for certification under Scheme-I of the BIS Conformity Assessment Regulations, 2018<\/strong>.<\/p>\n The standard covers Compregs intended for general purposes and specifically excludes the requirements for solid compressed wood.<\/p>\n IS 3513 (Part 3):1989 covers resin treated compressed wood laminates intended for general purposes<\/strong>.<\/p>\n The standard does not cover solid compressed wood.<\/p>\n The material can be supplied in different forms and configurations depending on the manufacturer’s product and intended application.<\/p>\n The standard identifies two principal grades for general-purpose Compregs.<\/p>\n GH is a partially impregnated high-density material suitable for applications such as:<\/p>\n The grade includes:<\/p>\n GM is a partially impregnated medium-density material intended for general purposes.<\/p>\n It includes:<\/p>\n These grades and types are identified in the BIS material describing IS 3513 (Part 3):1989.<\/p>\n The classification of Compregs is also based on the orientation of the grain in the veneers.<\/p>\n The applicable types include:<\/p>\n The exact grade and type should be selected according to the intended application and the requirements of the standard.<\/p>\n General-purpose Compregs are used in several engineering and industrial applications.<\/p>\n Typical applications include:<\/p>\n Compregs can be used for manufacturing textile machinery components such as:<\/p>\n They can be used for accessories and components used in jute processing machinery.<\/p>\n Compregs can be machined into components where good dimensional stability, mechanical properties and machinability are required.<\/p>\n The BIS description also identifies applications such as silent gears and spinning chucks.<\/p>\n The BIS Product Manual identifies the principal raw-material requirements for this product.<\/p>\n These include:<\/p>\n Timber requirements are specified with reference to Clause 5.1 of IS 3513 (Part 3).<\/p>\n Synthetic resins are required to comply with IS 848<\/strong> where applicable.<\/p>\n Varnishes are required according to the applicable requirements of the standard.<\/p>\n The Product Manual specifically identifies timber, synthetic resins and varnishes as relevant raw materials.<\/p>\n The manufacturing process generally involves several controlled stages.<\/p>\n Suitable timber is selected according to the requirements of the standard.<\/p>\n Thin veneers are prepared to the required dimensions and quality.<\/p>\n The veneers are impregnated or treated with suitable synthetic resin.<\/p>\n The treated veneers are arranged according to the required grain orientation and product type.<\/p>\n The veneers are subjected to controlled heat and pressure for bonding and densification.<\/p>\n Controlled curing ensures proper hardening of the thermosetting resin and bonding of the veneers.<\/p>\n The finished Compreg may be trimmed, machined, sanded or otherwise finished according to the product requirements.<\/p>\n The finished product is checked for dimensions, workmanship and applicable physical and mechanical properties.<\/p>\n IS 3513 (Part 3):1989 specifies physical-property requirements to help determine the suitability of Compregs for different applications.<\/p>\n These can include:<\/p>\n The required values depend on the applicable grade and type.<\/p>\n Mechanical performance is an important part of Compreg quality.<\/p>\n The standard addresses properties such as:<\/p>\n These properties help determine whether the material is suitable for its intended engineering application.<\/p>\n IS 3513 (Part 3):1989 also specifies dimensions and tolerances for different forms of Compregs.<\/p>\n Depending on the product form, dimensional checks can include:<\/p>\n The BIS Product Manual identifies dimensions and thickness as part of the product evaluation requirements.<\/p>\n Finished Compregs should meet the applicable requirements relating to workmanship and surface finish.<\/p>\n The Product Manual specifically identifies:<\/p>\n Thickness of veneers, dimensions and thickness, workmanship and finish<\/strong><\/p>\n among the requirements that can be evaluated.<\/p>\n The finished material should be properly manufactured, bonded and finished without unacceptable defects that could affect its intended use.<\/p>\n BIS Certification provides a conformity assessment mechanism for manufacturers whose products are covered by the applicable Indian Standard and regulatory requirements.<\/p>\n For Compregs for General Purposes, IS 3513 (Part 3):1989<\/strong> is included in the BIS product-manual system.
