ASTM D638, ISO 527

Applications

QT-UTM-HLT High and Low Temperature UTM Environmental System enables the testing of material and components under a variety of real world conditions. Cooperating with environmental chamber, XWW series machines can realize variety of tests at low or high temperature.

ASTM D638 Standard Test Method for Tensile Properties of Plastics. This test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pre-treatment, temperature, humidity, and testing machine speed.

Specimens are placed in the grips of the universal tester at a specified grip separation and pulled until failure. For ASTM D 638 the test speed is determined by the material specification. An extensometer is used to determine elongation and tensile modulus.

A thermal chamber is installed on the universal test machine. The chamber is designed to allow the test mounts from the base and crosshead of the universal tester to pass through the top and bottom of the chamber. Standard test fixtures are installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature. The chamber has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures. The size of the chamber places a limitation on the maximum elongation that can be reached, and extensometers are generally limited to no more than 200° C.

Features

  • It consists of three parts: main frame,grips and moveable high & low temperature cabinet.
  • Import full-digital AC servo system and high rigid structure enable high precision of the measuring result. The cabinet, with a double-heat insulation glass door, is convenient to observe the test; stainless steel test cabinet is resistant to corrosive.
  • It is nice in appearance, high in precision and easy to operate, also different kinds of grips shall be provided according to your requirement.
  • This kind of tester has been authorized CE certificate..
