Open Ended Slugging Wrenches (Spanners) are heavy‑duty hand tools widely used in industrial, construction, and maintenance applications. These wrenches have been especially designed to tighten or loosen the nuts. To achieve sturdiness and strength, it needs durable metal alloy or carbon steel materials.
The Bureau of Indian Standards has prescribed requirements under IS 4508:2024 to ensure the quality and performance of Spanners. These requirements ensure that all production materials maintain high quality while achieving hard material characteristics and precise dimension standards. Companies that comply with the Indian Standard are authorized to use the ISI mark on their slug wrenches. The certification system helps users to trust the efficient and safe operation of the wrenches which they will use.
This is the Indian Standard for Open-Ended Slugging Wrenches, which outlines the standard requirements for hardness, workmanship, dimensions and material. This standard is set by the BIS (Bureau of Indian Standards) to ensure that product quality and safety are met, and the spanners are :
BIS authorisation under IS 4508: 2024 is required for businesses involved in manufacturing, importing, or supplying open-end slugging wrenches in India. Applicable to:
To ensure consistent quality of industrial hand tools, the Bureau of Indian Standards has defined strict requirements for open-ended slugging spanners under IS 4508:2024. BIS certification ensures that manufacturers maintain standardized production practices and that users receive reliable, durable, and performance-tested tools suitable for heavy-duty applications. The BIS testing parameters and quality checks for Slugging Wrenches are listed below:
The BIS Authorisation process ensures that the slugging wrenches meet the required standards for proper and efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
Foreign manufacturers must additionally appoint an Authorized Indian Representative (AIR) to coordinate with the Bureau of Indian Standards (BIS) and manage compliance requirements in India.
When a manufacturer obtains BIS Approval, the ISI Mark for Plastic Water Supply Pipes must be clearly and permanently marked on its packaging or on the product. In addition to the ISI Mark, essential details such as the licence number (CM/L), manufacturer’s identification, etc. This ensures the product meets all quality and safety standards. More details are mentioned below:
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
The cost of BIS Approval for Polyethylene Pipe includes charges for application, inspection, license, testing, and marking. These fees are paid to BIS as per Scheme I guidelines.
Note:
As per IS 4508:2024, the Bureau of Indian Standards has outlined the minimum requirements for Open-Ended Slugging Wrenches/Spanners. This certificate assures that the tools are of constant quality during the production process. Moreover, the tools are fit for industrial use and safe when used correctly.
BIS certification is mandatory for companies manufacturing Slugging Wrenches to sell their products in India. It also helps in improving brand value in the Indian market. EVTL India supports manufacturers throughout the BIS certification process. It assists in documentation, application submission, testing coordination, and end-to-end compliance management.
