Introduction

Analysis of the core content of the standard

Technical elements	Parameter requirements	Test significance
Impact hammer weight	5±0.1kg	Simulation of actual motion impact load
Impact frequency	60±5 times/min	Standardized test rhythm
Abrasive cloth particle size	60# alumina	Uniform wear medium standard

Detailed explanation of key test equipment

The standard requires the use of a lifting mechanism (cam) to control the impact rhythm. Its core parameters include:

Impact height: 75±2mm

Effective grinding range: 45±5mm

Anvil moving speed: 100±5mm/s

Implementation recommendations and industry applications

Football stud test case

A certain brand of FG football studs was tested using this standard. Under the parallel sand tile (3101) medium:

Initial mass: 3.452g

Mass loss after 1000 impacts: 87.6mg

Wear pattern: uniform wear

Background of Standard Evolution

This standard integrates the technical requirements of GB/T2485-2016 abrasive tool standard and GB/T9867-2008 rubber wear resistance standard, and establishes a special test system for spikes for the first time, solving the pain point of the sports shoe industry's long-term lack of unified testing methods.
