LQ-P2

 Furniture surface impact resistance testing machine

一、 Main purposes and application scope:

The LQ-P2 furniture surface impact resistance tester is a device specially developed based on the standard ISO 4211-4 "Furniture - Tests for surfaces - Part 4: Assessment of resistance to impact". It is used for evaluating the impact resistance of furniture surfaces. The test is conducted by measuring the marks left by a steel ball after a falling hammer impacts at different heights. It is an essential testing instrument for furniture manufacturers, quality inspection departments, and also indispensable for research institutions in conducting new material research.

This equipment adopts a vertical structure design. The height of the hammer body is precisely controlled by an electric screw. The diameter of the lower hammer body is 39mm, the diameter of the steel ball is 14mm, and the maximum lifting height is 400mm. The impact height can be set arbitrarily according to the standard requirements. The hammer body is automatically released by an electromagnet. two Main specifications, technical parameters and technical indicators:
