FAQ
Q1: What standards does the Restrained Expansion Dilatometer for Shrinkage-Compensating Concrete comply with?
A1: The Restrained Expansion Dilatometer for Shrinkage-Compensating Concrete 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 Restrained Expansion Dilatometer for Shrinkage-Compensating Concrete 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.
