Features of SATRA STM 439 – Shoelace Durability Tester:
- SATRA STM 439 is a versatile shoelace abrasion tester, designed to evaluate durability through two methods: Lace to Lace (lace to lace) and Lace to Carrier (lace to carrier/buckle). The machine simulates the repetitive friction process in real-life conditions of use, providing fast, accurate and highly repeatable test results.
- Lace to Lace method: Two similar shoelaces are rubbed together. Before testing, the shoelaces need to be stabilized in standard atmospheric conditions for at least 48 hours. One lace is clamped at both ends, the other is threaded through the loop and attached to a weight that creates a tension of 2.45N. The machine moves the laces back and forth 35 mm at a speed of 60 cycles/minute, creating friction until the lace breaks. Each station has its own counter and will stop automatically when a lace breaks; the whole machine stops when all 6 laces break.
- Lace to Carrier Method: Use the same equipment to test the durability of shoelaces when rubbing against the lace-holding details such as eyelets, D-rings, ski hooks, metal hooks and similar accessories.
- 6 independent test stations: help test multiple samples at the same time, saving time.
- Safe & easy to use: with a control handle for convenient installation, equipped with a full shielding system, complying with European Health & Safety requirements.
