ISI / BIS Certification for Resin treated compressed wood laminates (compregs) – For electrical purposes

Because of their special blend of mechanical strength and electrical insulating qualities, resin-treated compressed wood laminates, often known as "compregs," have proven to be highly useful in electrical applications. These laminates are made by compressing and curing layers of premium resin-impregnated wood veneers or fibers under heat and pressure. Compregs are prized in electrical engineering for their outstanding electrical insulating qualities, which fit them for the manufacture of insulators, electrical panels, and other parts where it's essential to avoid electrical conductivity. Their minimal moisture absorption, voltage resistance, and dielectric strength are useful for preserving secure and dependable electrical systems.

Compregs are also used in the production of electrical insulation materials, including components for circuit breakers and insulation for transformer coil windings. They are perfect for situations where maintaining the integrity of electrical insulation is crucial because of their capacity to tolerate significant electrical stress and mechanical stresses. The Indian Standard IS 3513 (Part 1):1989 lays out the specifications for compressed wood laminates (compregs) coated with resin intended for use in electrical applications. Adherence to IS 3513 (Part 1):1989 guarantees that the components are produced in a way that satisfies particular dielectric strength specifications, protecting the electrical insulation's integrity. For materials used in electrical equipment, compliance with these established standards, such as IS 3513 (Part 1):1989, is frequently required by law. Producers that follow these guidelines make sure their goods meet legal requirements, which lowers the possibility of legal problems and liabilities.

Note: Prior to releasing their goods onto the Indian market, producers of resin-treated compressed wood laminates (compregs) intended for electrical applications must get ISI Mark Certification.

Electrical insulation applications and other electrical components depend heavily on these specialist materials, and their quality, safety, and performance are vitally ensured by ISI certification. It means that these composites have been put through a thorough testing process and meet the strict standards set by the BIS, with an emphasis on their electrical insulating qualities. With this certification, you may be guaranteed that the resin treatment and other production processes adhere to the required requirements, producing composites with superior electrical insulating properties, high dielectric strength, and resistance to electrical tracking.

About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Documents Required for ISI / BIS Certification

The following documentation is required to get an ISI certification:

• Main Application Form V
• Address Proof of Manufacturing Unit
• Details of Manufacturing Process
• Test Report of products

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

• Regular Procedure
• Simplified Procedure 

Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

• Preparing an Internal Test Report for the product by the relevant Indian Standard
• Compiling all necessary documents
• Completing the Online Application Form
• Online payment of application fees directly to BIS
• Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

• Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
• Conducting product sample testing at a BIS-recognized testing laboratory

ISI Mark Certification Process for Foreign Manufacturers

The process of obtaining ISI Mark Certification for Foreign Manufacturers typically includes the following steps:

Step 1: Application

• Compile all the required documents.
• Submit the documents along with the Application Fee.
• An Application Number will be allotted.
• Scrutiny of the Application will be conducted within a specified time frame.​

Step 2: Query Raised (If Any)

• If any documents are missing or there is non-compliance, you will be informed.
• You need to submit a reply within the given timeframe.
