Introduces automation to a manual & time consuming test. Standardize Stress Crack Testing across your orginization. User safety, constructed to CE standard. Complies with the ISBT test method. configuration Automatic or Semi Automatic 6 or 12 Test Heads about Stress Cracking: Typically PET environmental Stress Cracking originates around the base of the bottle. There are many factors which can cause it. The Intrinsic Viscosity of the Preform used to blow the bottle. Control of process and cooling parameters during the moulding process. Contact with line conveyer lubricants during manufacturing. Contact with solvents and other chemical based cleaning agents while on the shelf. For more details click here about the test: Performance of samples can be evaluated when the base of the bottle is immersed in a NaOH (Sodium Hydroxide) solution which simulates failure associated with Stress Crack. Prior to immersion the bottles are filled (to fill level) with water and pressurized. Failure results in a pressure loss or burst of the bottle. Full Automatic Configuration
