ISI / BIS Certification for Fasteners – Threaded Steel Fasteners – Hexagon Head Transmission Tower Bolts

In the building and upkeep of transmission towers, threaded steel fasteners more especially, hexagon head transmission tower bolts are essential. Because of their hexagonal heads, these bolts are simple to install and remove with a wrench or socket. They are essential in maintaining the integrity of the lattice structures, braces, and other components that make up transmission towers. Long-distance electrical power transmission is one instance of high-stress settings where their sturdy construction guarantees a secure and reliable connection. For a dependable and long-lasting connection, these fasteners are frequently used with nuts and washers.

Indian Standard IS 12427:2001 lays forth specifications for hexagon head transmission tower bolts, which are threaded steel fasteners. Adherence to IS 12427:2001 facilitates the production of bolts by manufacturers that are resilient to the loads and environmental factors related to transmission towers. By following IS 12427:2001, bolts are guaranteed to be strong and long-lasting enough to perform this function, preventing structural failures and guaranteeing a steady supply of electricity. Producers that follow these guidelines make sure their goods meet legal requirements, which lowers the possibility of legal problems and liabilities.

Note: The obligatory ISI Mark Certification must be obtained by manufacturers of fasteners, especially those that manufacture threaded steel fasteners with hexagon head transmission tower bolts.

To guarantee the dependability and safety of these essential parts used in the building and upkeep of transmission towers—which are essential for the operation of the electrical power infrastructure—ISI certification is an essential quality assurance tool. This certification shows that the fasteners have passed thorough testing and meet the strict requirements set by the BIS. It ensures that the right steel materials and production techniques are used in the fabrication of these bolts, guaranteeing their strength and durability to the harsh circumstances seen in transmission tower installations.

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.

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
