Pendulum friction tester measuring skid resistance (BPN) of road, runway and floor surfaces in the field or laboratory.
Overview
With the development of transportation, the skid resistance of highways, urban roads, airport runways and other pavements has received widespread attention. The Pendulum Skid Resistance Tester (referred to as pendulum tester) is an instrument used to measure the coefficient of friction of pavements, airport runways, marking paints and other surfaces. It can also be used as a basis for determining various tire formulations by measuring the friction coefficient of typical pavements. This instrument is a commonly used testing instrument in highway, urban road, airport runway and pavement material research units in China. It is characterized by simple structure, convenient operation and high accuracy, and the test results comply with the relevant provisions of current national standards. It can be used both indoors and in the field.

FAQ
Q1: What standards does the Pendulum Skid Resistance Tester comply with?
A1: The Pendulum Skid Resistance Tester is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Pendulum Skid Resistance Tester be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
