A key reason why JCS products are so trusted and reliable is the process of continuous scrutiny and improvement employed by our technicians. At the heart of this methodology is an on-going testing programme, performed at our in-house testing facilities, which ensures the quality of the hose clips is maintained at the highest possible level.
Every worm-drive clamp we produce is manufactured to exceed BS 5315. The British Standard has the highest requirements of any of the international standards and our internal levels surpass these by at least 20%.
Typically we test three principal aspects our hose clamps:
TORQUE
A torque test refers to the twisting force a hose clip can withstand. Different size clamps are put on appropriate sized conical bars and tightened to set limits. This is achieved using a torque meter which measures the tightening torque.
These tests are employed across the whole range including our hi-torque clamps and data for each product is published on the website.
CLAMPING ABILITY
Our clamping tests measure the actual clamping force of a hose clip. A clamp is mounted on 2 semi-circular mandrels and as the clamp is tightened around these they come together, by measuring the movement we can accurately calculate the clamping force.
PRESSURE
Our pressure tests ensure that hose clips can hold a seal at industry standard pressure and beyond. This simple but effective assessment is achieved by clamping a hose clip around both ends of a rubber hose and then forcing water through at a set pressure. Checks are then made to ensure the seal has been maintained and that no leaks or loss of liquid can be found. This test is often the most critical as strangely certain designs of clamps can have very good Torque and Clamp readings but fail this test even on very low pressures…. not the case with any JCS clamps as they seal uniformly around the whole circumference of the hose.
