EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4646 testing. It determines the lowest temperature at which the specified fabrics will not break or crack the coating when subjected to certain impact conditions. One appendix concerns speed calibration of a solenoid-operated low-temperature impact tester.
Rubber or plastic coated fabrics are used in many applications involving low temperature stretch with or without impact. The data obtained by this method can only be used to predict the behavior of these coated fabrics at low temperatures in applications where the deformation conditions are similar to those specified in the method.
Prepare the insulated tank and bring the apparatus to the desired temperature. This can be accomplished by placing the appropriate amount of solid carbon dioxide (dry ice) in the tank and slowly adding the heat transfer medium until the tank is filled up to 50mm from the top. During testing, the temperature of the bath should be kept constant by the judicious addition of a small amount of dry ice.
ISO 4646 specifies requirements for test apparatus, including pendulum, temperature control system, and instrumentation for measuring impact force and energy. The standard also specifies test conditions, including temperature range and impact energy levels, and provides guidance on sample preparation and handling.
Overall, ISO 4646 is an important standard for manufacturers and designers of rubber or plastic coated fabrics because it provides a standardized method for evaluating the low temperature impact performance of these materials. By following this standard, manufacturers can ensure that their coated fabrics can withstand sudden impacts at low temperatures and meet performance standards required for a variety of applications.
