Centre Punch For IEC 62368-1:2023 Annex T 10 Glass Fragmentation Test

Product Overview

The SN2210-28 Centre Punch is a specialized glass breakage test tool designed to evaluate the shattering performance of accessible glass panels in household appliances, lighting equipment and electrical products. It features a 75g ± 5g impact body and a precision-ground conical tungsten carbide tip with a 60° ± 2° angle.

Designed for compliance testing in accordance with relevant IEC safety standards, this glass panel breaking test punch helps laboratories and product manufacturers assess glass breakage characteristics during electrical product safety evaluations.

Key Features

• Standard-Compliant Design: Suitable for glass shattering tests specified in IEC 62368-1, IEC 60598-2-3 and relevant IEC 60335 series standards.

• Tungsten Carbide Tip: Conical testing tip designed for concentrated impact on accessible glass surfaces.

• Controlled Test Parameters: Specified mass of 75g ± 5g and tip angle of 60° ± 2°.

• Wide Testing Applications: Suitable for glass panels used in household appliances, lighting products and electrical accessories.

• Laboratory Testing Solution: Ideal for electrical safety laboratories, product compliance testing facilities and manufacturer quality control departments.

Applications

The SN2210-28 glass shattering test punch is used to assess the breakage behavior of accessible glass panels incorporated into electrical and household products.

Typical test applications include:

• Household Appliances: Accessible glass panels on ovens, cooking appliances and other household electrical equipment.

• Lighting Equipment: Glass covers and accessible glass components of luminaires.

• Electrical Accessories: Glass panels and protective glass components used in electrical products.

• Product Safety Laboratories: Glass breakage evaluation during IEC compliance testing and electrical product safety assessments.

Applicable Standards

The SN2210-28 is designed for testing applications referenced in the following international IEC standards and clauses:

Test Principle & Procedure

The glass breakage test is performed by applying a localized impact to the accessible glass panel using a specified centre punch.

1. Position the Test Punch: Place the punch approximately 13 mm inward from the longest edge of the glass, at the midpoint of that edge.

2. Apply the Impact: Strike the test punch with a hammer to transfer the impact force through its conical tungsten carbide tip.

3. Observe Glass Breakage: Examine the glass after impact to evaluate its shattering behavior in accordance with the applicable test requirements.

The test punch has a specified mass of 75g ± 5g and a conical tip angle of 60° ± 2°.
