Standard Specification for Tensile Testing Machines for Textiles
STANDARD published on 1.7.2021
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers operating characteristics of tensile testing machines for the determination of the force-elongation properties of textile materials. Types of tensile machine covered in this specification are constant-rate-of-extension, constant-rate-of-traverse, and constant-rate-of-loading. Testing machines calibration shall be verified using the methods indicated in this specification, especially when moved to different locations to make sure that they still meet the specified tolerances. Motor-driven machine is preferred over manually driven machine. Constant-rate-of-traverse type machines shall not be used for measuring forces below fifty times their resolution. Machines shall be equipped with a device for measuring force. Clamping or holding devices shall be prescribed in test methods. Maximum allowable error, indicated force, recorded elongation, nominal gage length, and moving clamp speed shall be within the tolerances prescribed in the individual standards. Verification methods for recorded clamp displacement, recorded elongation, and nominal gage length, shall conform to the procedures indicated in this specification.
