Athol, Massachusetts– The L.S. Starrett Co. has introduced a spring testing solution for compression and extension springs. The Starrett S1 Spring Testing Systems were developed for high-volume production testing for users seeking more consistent results over manual testing methods.

Starrett S1 Systems feature test templates that enable the user to create a test set up in seconds using one and two-point methods, with test targets being load or height-based. In addition, the small footprint of the S1 System makes it suited for in-situ production areas. Spring rate, spring constant, free length, solid height, and initial tension can be measured, and tolerances can be used to determine immediate pass/fail results, viewable in graphic or tabular formats.

Software features of Starrett S1 Spring Testing Systems enable the use of preconditioning options to exercise springs prior to testing, the ability to scrag for a number of cycles or duration or compress to a load set and hold for a duration. Single or dual test limits may be used and target load or height/length for determining spring rate, spring constant, load, and length at target limits; initial tension and measured free length can be specified.

The system’s statistics view displays key statistical information for the user’s batch including mean, range, standard deviations, and tolerance results. Custom reports can also be printed and data can be exported to Microsoft Excel or SPC Software such as ProLink’s QC CALC application.
