IS 12427: 2001 – FASTENERS – THREADED STEEL FASTENERS – HEXAGON HEAD TRANSMISSION TOWER BOLTS

IS 12427:2001 covers the requirements for hot dip galvanized hexagon head transmission tower bolts in the size range M12 to M24 for use in the construction of transmission towers, sub-stations and similar steel structures. 1.2 The bolts covered in this standard are not suitable for applications requiring improved low temperatures characteristics. Unless otherwise specified, the bolts shall be ofproduct grade C as specified in IS 1367 (Part 2). The bolt threads shall be in accordance with IS4218 (Parts 1 to 4) and prior to hot-dip galvanizing shall conform with Go and Not Go threaded ring gauges in accordance with IS 2334. The tolerance on threads shall be 8 g. The hexagon nuts used with these bolts shall conform to the requirements given in IS 14394. The plain washers used with these bolts shall be of Type A, punched washer type and shall conform to the requirements of IS 2016 except the thickness of washers which shall be 5 + 1 mm. The bolts shall be of property class 5.6, 5.8 or 8.8 as specified in IS 1367(Part 3) and shall be tested full size. The standard covers the specifications for dimensions, material, mechanical properties such as shear strength.

QUALITY CONTROL ORDER (TECHNICAL REGULATION) ISSUED BY THE DEPARTMENT FOR PROMOTION OF INDUSTRY AND INTERNAL TRADE, MINISTRY OF COMMERCE AND INDUSTRY, GOVT. OF INDIA ON 21 JULY 2023 FOR MANDATORY BIS CERTIFICATION

The DPIIT, Ministry of Commerce & Industry, Govt. of India, has issued an order, making it mandatory for all fasteners to be used in India, whether manufactured in India or imported from foreign countries, shall mandatorily carry the Standard Mark of the Bureau of Indian Standards under a valid BIS licence.  In short, it has become obligatory for all the manufacturers of fasteners, wherein in India or overseas, to immediately apply for BIS licence and obtain a valid BIS certification licence before that the last date of implementation of the order, i.e., 20 January 2024.

BIS CERTIFICATION SCHEME

The BIS Standards, IS 6623, IS 10238 and IS 12427, establishes a comprehensive framework encompassing various quality parameters that fasteners must adhere to. The Bureau of Indian Standards Certification Scheme is a vital framework established by the Indian government to ensure the quality, safety, and reliability of products available in the market. This scheme aims to safeguard consumer interests by setting stringent benchmarks and guidelines that products must meet before they can be deemed compliant. BIS certification covers a wide range of industries and products, encompassing the entire gamut of industrial and manufacturing activity.  Various steps involved in the BIS Certification process are enumerated below:

• Standard Identification: Manufacturers identify the relevant BIS standard that applies to their chosen product category. These standards outline the specific quality, safety, and performance requirements that the product must meet.
• Application Submission: Manufacturers submit an application for BIS certification to the Bureau of Indian Standards (BIS), providing details about the product, its specifications, and the desired certification mark.
• Factory Inspection: BIS conducts an inspection of the manufacturer’s production facility to assess the quality control processes, infrastructure, and adherence to relevant standards.
• Sample Testing: BIS collects samples of the product from the manufacturer for testing in authorized BIS laboratories or recognized testing centers. These tests evaluate various parameters specified by the BIS standard.
• Certification Decision: Based on the satisfactory test results and compliance with standards, BIS decides whether to grant certification to the product. If approved, the manufacturer is issued a BIS certification license.
• Regular Monitoring: BIS monitors the manufacturing process of certified products through periodic audits and market surveillance to ensure ongoing compliance with quality control processes and standards.
