Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.
Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.
Product technical specifications and images may vary according to manufacturing conditions and applicable standards.
Test and configuration
- Measured output / function
- Kinetic coefficient of friction of yarn against a solid surface
- Parameters selected for the method
- Input tension, wrap angle, yarn speed and contact surface
- Verification points
- Input/output tension channels, wrap angle and yarn speed
Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.
Test parameters for the reviewed method
Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.
ASTM D3108-01 · 6.1.1-6.1.3, 11
- Indirect yarn-friction measurement uses input and output tension measurement within ±1 mN, with input control also within ±1 mN. Coefficient calculation uses tension ratio and contact angle together; store wrap angle in radians.
TS 7475:2004 · 1.2.1.1-1.2.1.3, 1.6-1.7
- Yarn/solid friction requires ±1 mN input/output tension accuracy; reference contact diameter 12.7 mm. Unless otherwise specified, use 100 m/min and wrap angle π or 2π; coefficient = ln(T2/T1)/θ. Verify the model's existing ±1% declaration separately against the ±1 mN requirement.
Control and recording specification
The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.
- Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
- For the indirect method, μ = ln(T₂/T₁)/θ with angle in radians and tensions in the same unit. Record mean input/output tensions and the validity conditions of the method.
- Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
- Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
The ASTM D3108-01 channel requirement of ±1 mN is not equivalent to the model accuracy statement of ±1%. Verify the basis of the percentage statement and channel calibration over the applicable working range.
