The 75g test punch with 60° conical tungsten carbide tip is a specialized test tool designed for IEC‑standard accessible glass shattering test, widely adopted by third‑party certification laboratories, manufacturer QC departments and R&D centers across the globe.
Unlike ordinary steel test punches, its tungsten‑carbide conical tip maintains consistent geometry after hundreds of impact cycles, eliminating dimension drift that leads to inconsistent test results. This test fixture verifies safety performance of accessible glass panels fitted on household appliances, lighting luminaires and electrical accessories. It simulates real‑world impact stress to check whether glass breaks in a safe mode, which is a mandatory item for global product safety certification.
Key Features
Strictly follows IEC standard parameters: total mass 75 g ±5 g, tip angle 60° ±2°, conical profile, fully meets IEC 60335‑2‑24 and related cross‑reference standards
Premium tungsten carbide tip: extreme hardness, outstanding wear‑resistance, long service life, avoids frequent replacement and measurement deviation
Reproducible test performance: stable tip shape guarantees repeatable fracture results for glass‑panel shattering assessment
Ready‑to‑use for standard test procedure: position approx.13 mm inward from mid‑point of glass longest edge; strike the punch with hammer to implement shatter test
Suited for certification testing, incoming quality inspection, production‑line QC and new‑product R&D validation
