Introduction

In the process of analyzing and summarizing mechanical injury incidents caused by consumer products, it was found that sharp edges are a major cause of mechanical injuries caused by consumer products.

The sharp edges of consumer products are often found on the market, causing serious cuts to consumers.

The engineering analysis test mainly evaluates the injury risk by simulating injury scenarios. Market regulators and producers are prone to disagreement on the evaluation results.

This is not conducive to the implementation of consumer product defect investigation and recall work, so it is urgent to standardize the defect engineering analysis test of sharp edges of consumer products. method.

This document is intended to standardize the defect engineering analysis test method for sharp edges of consumer products. The main principle is to use materials that simulate human skin to The sharpness of the tested edge is quantitatively evaluated based on the degree of penetration of the simulated skin material by contacting the accessible edge of the consumer product with a certain force and speed.

level, ensuring the repeatability and consistency of the sharp edge defect engineering analysis results, effectively reducing the differences between market regulators and manufacturers, and reducing Reduce the harm caused to consumers by sharp edges.

3 Terms and definitions

The following terms and definitions apply to this document.

4 Principle

The edge being tested is judged to be a touchable edge by using a touchable probe, and a sharp edge tester covered with three layers of test tape is used to simulate a human The scene where the skin touches the edge of the consumer product, moves a certain distance at a speed of 0.02m/s~0.05m/s on the touchable edge of the consumer product Finally, the sharpness of the edge is assessed by checking the penetration of the test tape.

5 Environmental conditions

Simulate the environmental conditions and scenarios in which consumer products are actually used.
