Water-resistant or wishful thinking?

Put upper materials to the test with the SATRA STM 606D machine.

When it comes to performance footwear, water resistance is not optional – it is expected. The SATRA STM 606D Maeser water resistance tester can help you to ensure that your upper materials live up to the promise made to the customer.

Designed to replicate the real-world conditions of flexing during wear, STM 606D exposes footwear upper materials to a true test of endurance – repeated flexing while in contact with water, just as the vamp of a shoe may experience during walking.

Manufactured in the UK, the SATRA STM 606D delivers accurate, repeatable insights into how materials respond to water when under stress. This allows manufacturers to fine-tune material choices, construction methods and quality control before a single pair reaches the customer.

This precision test machine allows testing with confidence to trusted industry methods, including SATRA TM34 and ASTM D2099-90.

Why choose the STM 606D?

• simulates real-world flexing under wet conditions
• predicts water resistance failure points in upper materials
• compact, fully enclosed and user-friendly design
• complies with industry test methods
• delivered ready to test, with accessories and traceable calibration.
