A MANUAL STRESS CRACK TESTER IS A DEVICE TO TEST A PLASTIC BOTTLES ABILITY TO WITHSTAND INTERNAL PRESSURE. TYPICALLY A BOTTLE IS FILLED WITH WATER UP TO THE FILL POINT, AN ADAPTOR IS PLACED INSTEAD OF THE USUAL CAP, IT IS PLACED IN THE MACHINE AND 5 BAR AIR PRESSURE APPLIED, THE BASE OF THE BOTTLE SITS IN A CAUSTIC SOLUTION TO ACCELERATE DEGREDATION OF THE BOTTLE. TIME FOR BOTTLE TO BURST IS MONITORED AND RECORDED. THE VALVES ARE OPENED MANUALLY, BOTTLE FAILURE AND TIME MONITORED BY OBSERVATION.

A MECHANICAL FIXTURE USED TO TEST THE IMPACT STRENGTH OF PLASTIC BOTTLES DROPPED IN THE VERTICAL OR HORIZIONTAL POSITION FROM A PRESET HEIGHT. IT COMPRISES OF A FRAME 1.8M HIGH MADE FROM STAINLESS STEEL AND ALUMINIUM FACILITATING THE SAMPLE TO BE DROPPED TO IMPACT WITH A HEAVY STAINLESS STEEL PLATE.

MACHINE USED IN BEVERAGE PACKAGING QUALITY ASSURANCE LABORATORIES TO TEST A PLASTIC BOTTLES ABILITY TO WITHSTAND THE HIGH TEMPERATURES ASSOCIATED WITH THE "HOT FILL" PROCESS. THE DEVICE IS USED TO FILL A MEASURED VOLUME OF HOT WATER (USUALLY 80*C) INTO THE BOTTLE UNDER CONTROLLED/LABORATORY CONDITIONS. THE SAMPLE BOTTLE IS THEN EXAMINED VISUALLY.

AN ELECTRO MECHANICAL DEVICE USED TO TEST THE IMPACT STRENGTH OF MATERIALS. IN ITS CURRENT DESIGN IT IS USED BY BEVERAGE PACKAGING LABORATORIES TO TEST PLASTIC BOTTLES.
