Standard test sieves for particle size analysis and grading of sand, stone, aggregate, soil and powder in laboratories.
Overview
The Standard Test Sieves is suitable for particle size analysis and grading inspection of granular materials such as sand, stone, aggregate, soil and powder in laboratories. This series includes various specifications such as stone screens, sand and gravel screens, round-hole screens, square-hole screens, cement fineness screens, fly ash screens and asphalt screens. The screen frames are made of metal or engineering plastic, with flat screening surfaces and accurate apertures, and are widely used in highway, water conservancy, construction, building materials, quality inspection and other industries.
Applications
• Fine and coarse aggregate gradation analysis
• Concrete and asphalt aggregate quality control
• Aggregate crushing value and abrasion resistance testing
• Ready-mix concrete plant and aggregate quarry laboratories
Features
• High measurement accuracy with stable repeatability
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Standard Test Sieves comply with?
A1: The Standard Test Sieves 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 Standard Test Sieves 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.
