Scope of Application
【Operating Instructions】
Applicable Scope:
Used to determine the tensile creep and tensile creep rupture properties of geotextiles and related products.
Compliance Standards:
Complies with ISO 13431, GB/T 17637, JTG E50 T1129, SL/T 235-1999, and other standards.
Instrument Features:
Number of Stations: 4 stations (other options include 2, 6, or 12 stations). Each station operates independently without interference.
High-Precision Recording: Uses encoders to record creep elongation with high accuracy.
Pneumatic Loading: Uses air pressure instead of weights, making it convenient to apply constant loads.
Precise Pressure Control: Utilizes SMC electro-pneumatic proportional valves to adjust air pressure in real-time, ensuring constant applied pressure.
Cylinder System: Uses Airtac cylinders; small cylinders are used for low force values, and large cylinders are used for high force values.
