The samples are then released from the fixture and allowed to relax for 10 minutes. The fixture stretches the samples to the specified elongation and holds them for 10 minutes. The samples are carefully mounted in the test fixture to provide uniform alignment and position. The initial length between these marks is measured for each sample. Two marks are precisely placed on each test sample at the ends of the gauge length of the dumbbell shaped specimens. Test samples are typically die cut from large sheets. This elongation consists of both permanent and recoverable components - thus the time for stretching and recovery are important factors, and both are specified by D 412. Tensile set testing of a rubber or thermoplastic elastomer evaluates the residual elongation of a test sample after being stretched and allowed to relax in the specified manner. Type: made of stainless steel, with fixed stainless steel nozzle, orifice No.Tensile Set of Rubber and Thermoplastic Elastomers ASTM D412 Type: made of stainless steel, with fixed stainless steel nozzle, orifice No. Optional: possible to certify by calibration with certified oils TQC Viscosity Cup ASTM D1084 D4212 Immersion Zahn TQC viscosity cups are made under the continuing quality control procedures.Įach cup is provided with an engraved unique serial number. The design of the cup and orifice eliminate hard to clean recesses. Ideal for measuring coatings and other fluids during application or production.Įach cup has a long handle to allow the cup to be dipped by hand into a liquid container, which makes it easy to quickly check and adjust the viscosity of many different type of liquids. The TQC Viscosity Cup ASTM D1084 D4212 Immersion Zahn is a range of stainless steel (SS303) viscosity cups with fixed stainless steel inner cavity nozzle and handle.
