NJHF-II Type Ceramic Tile Coefficient of Restitution Tester
简要描述: The ceramic tile recovery coefficient tester determines the recovery coefficient by dropping a steel ball onto a test specimen from a fixed height and measuring the rebound height.
产品介绍
I. Overview of the Ceramic Tile Recovery Coefficient Tester
The ceramic tile recovery coefficient tester determines the recovery coefficient by dropping a steel ball onto a test specimen from a fixed height and measuring the rebound height. By measuring the recovery coefficient, the impact resistance of various tiles is determined, in accordance with the requirements of national standard GB/T 3010.5-2016 and ISO 10545-5: 1996 “Determination of impact resistance by measurement of coefficient of restitution.”
II. Technical Specifications of the Ceramic Tile Rebound Coefficient Tester
1. Fixed drop height: 1 m
2. Steel ball dimensions: Chromium steel ball with a diameter of (19 ± 0.05) mm
3. Time measurement accuracy: Accurate to the millisecond
4. Reference dimensions (L × W × H): 280 × 360 × 1300 mm
