The ITM-LAB RS-6550-6 tests eyeglass hinge durability by repeatedly opening and folding the temples. A central fixture holds the frame front while separate mechanisms move the left and right temples. Set the test angle from 0° to 200°, the speed from 5 to 60 repetitions per minute, and the target count from 1 to 999,999.
The ITM-LAB RS-6550-6 is an eyeglass hinge tester that repeatedly opens and folds the arms of a spectacle frame. A central fixture holds the frame front while mechanisms on either side move the temples. Operators can set the test angle, speed and target count for hinge durability testing. Request a Quote
Watch the demonstration to see how the frame front is secured and how the mechanisms on either side move the temples during the test.

When estimating test duration, confirm how the controller counts a complete opening and folding sequence. Select an angle within the safe travel of your sample and the limits of your test method.
A temple folding test repeatedly opens and closes the arms of an eyeglass frame at a specified angle and rate. The frame front stays fixed while the temple mechanisms move the arms about their hinges. After the target count, the operator checks the sample against the test plan.
Mount the frame. Secure the frame front in the central fixture and align the two mechanisms with the temple positions.
Check the motion. Verify that the temples can travel through the required angle without contacting the fixture or surrounding parts.
Run the test. Set the angle, speed and target count, then run the opening and folding sequence specified in your procedure.
Inspect the sample. Compare the condition and operation of the frame and hinges with the acceptance criteria below.
Fixture fit depends on the shape of the frame front, the position of the hinge pivots and the space the temples need as they move. When checking a sample, review these points.
| What to check | What to send ITM-LAB |
|---|---|
| Frame front and clamping area | Front photo or dimensioned drawing showing the frame width and potential clamping area |
| Hinge position and temple dimensions | Side and top views showing the pivots, temple length and thickness near each hinge |
| Opening and folding clearance | Required start and end positions, especially if the temples overlap when folded or have protruding housings |
The machine shown has two test levels with three frame mounting positions visible on each level. The transparent front doors open for sample installation and fixture adjustment. Slots, locking screws and scales are visible on the positioning mechanisms.
Check Sample Fit
Spectacle frames. Eyewear manufacturers and quality labs can use the RS-6550-6 for repeated opening and folding during design evaluation and production quality checks. With the same setup and test conditions, teams can compare how different frames or hinge designs behave after testing.
Smart glasses and AR eyewear. For smart glasses hinge durability testing, review the mechanical fit around thicker temples and electronics housings before selecting a fixture. If the test plan also requires electrical continuity, display or optical checks, include the separate measurement requirements when requesting a quote.
Before testing, agree on the sample setup, start and end positions, speed, target count and inspection criteria. Use the same documented settings when comparing samples. Depending on the test plan, inspect for loose screws, cracks near the hinge or temple, damage to the frame connection, or changes in how the arms open and close.
If your project follows a customer test method or a spectacle frame standard, send the applicable edition and clause with your inquiry. ITM-LAB can review the requested fixture arrangement and motion against the proposed machine configuration.
Send a sample photo or drawing and your required angle, speed and target count. If you have a written test procedure, attach it so ITM-LAB can review the fixture and test settings with your quotation.
Torque measurement is not listed in the RS-6550-6 specification. If your test calls for breakaway torque, running torque or a torque-versus-angle record, include that measurement requirement in your inquiry.
Use the count required by your product specification, development plan or applicable test method. The maximum setting of 999,999 repetitions describes the controller's range. Your acceptance criteria determine whether the sample passes.
Suitability depends on the space around the hinge and temple throughout the requested movement. Send the temple cross-section or thickness, a hinge close-up and the open and folded positions so ITM-LAB can review fixture clearance.
The photographed setup has local buttons labeled for left and right opening and folding. If your test requires different settings or counts for each side or sample position, include that requirement so ITM-LAB can confirm the control configuration.
