Car repair expansion bolts, often referred to as expansion anchors, typically need to conform to specific international or regional standards to ensure their quality and performance. Here are some common standards related to car repair expansion bolts:
ISO Standards: The International Organization for Standardization (ISO) has issued multiple standards covering the requirements for expansion bolts, including their dimensions, performance, testing methods, and more. ISO 898-1 covers the classification and testing methods for mechanical properties, while ISO 898-2 outlines requirements for threads and appearance.
ASTM Standards: The American Society for Testing and Materials (ASTM) has developed several standards for evaluating and testing the performance of expansion bolts used in construction and structural applications. ASTM F1554 covers requirements for high-strength structural bolts, while ASTM A307 covers requirements for general-purpose bolts.
EN Standards: The European Committee for Standardization (CEN) has published some standards for assessing the performance and quality of expansion bolts. EN 1992-4 standard covers requirements for mechanical fasteners used in concrete structures.
ANSI Standards: The American National Standards Institute (ANSI) has released various standards covering requirements for bolts and nuts, some of which may apply to expansion bolts.
The Standardization Administration of China (SAC) has published national standards applicable to expansion bolts used in construction and structural applications. Here are some Chinese standards relevant to car repair expansion bolts:
GB/T 22521-2008 "Classification of Metal Materials for High-Strength Structural Bolts": This standard specifies requirements for the classification, specifications, dimensions, materials, and performance of high-strength structural bolts, including expansion bolts used in construction and structural engineering.
GB/T 3098.1-2010 "Mechanical Properties of Fasteners - Part 1: Bolts, Screws, and Studs - Product Grades A": This standard covers general requirements for hexagon head bolts, screws, and nuts, including car repair expansion bolts. It specifies requirements for bolt materials, dimensions, and performance.
GB/T 3098.6-2010 "Mechanical Properties of Fasteners - Part 6: Bolts, Screws, and Studs - Product Grade C": This standard is similar to Part 2 but pertains to fasteners of product Grade C, including some expansion bolts.
Car repair expansion bolts, as a type of expansion bolt, should adhere to the relevant national standards in China for construction and structural engineering to ensure their quality and performance.
