Testing technology for plastics testing

• Industry: Plastics industry

The tensile test according to ISO 527-1 or ASTM D638 can be used to determine key mechanical properties of plastics such as tensile strength, yield strength and modulus of elasticity.

• Industry: Automotive industry, medical technology, construction industry

The ISO 37 or ISO 037 test standard deals with the determination of the tensile strength and elongation of rubber and elastomers. The standard ensures that the mechanical properties of the two materials are tested under standardised conditions so that the results are comparable. The results ensure that products made from these materials meet the required specifications and quality standards.

The mechanical properties of thermoplastic pipes are of great importance for their possible applications in various branches of industry. ISO 13968 specifies the test methods for determining the ring flexibility of pipes to ensure that the materials can withstand the requirements of bending stresses. According to this standard, the following can be tested with apex pressure testing machines from Hegewald & Peschke.

Compression tests on hard foams in accordance with ISO 844 are used to determine mechanical properties such as compressive strength, compression, compressive stress and the compressive modulus. These tests are essential to evaluate the mechanical strength of rigid foams and similar materials and to ensure that they meet the requirements of various applications.

Textile structures are extremely versatile. Geotextiles, for example, are often used in the construction industry. Depending on the wide range of possible applications, a wide variety of tests can be carried out on textile materials.

Carbon fiber reinforced plastics (CFRP), commonly known as carbon, are characterized by their high strength combined with low weight. These properties make them ideal for applications in aerospace, automotive, and sports equipment industries. The testing system is used to determine the mechanical properties of composite samples by means of tensile tests (e.g. according to ASTM D3039 & DIN EN ISO 527) and bending tests (e.g. according to ASTM D790 & DIN EN ISO 14125.

GRP pipes are often part of a critical network in civil engineering, for energy suppliers or in other industrial plants. Often, not only they do transport relatively harmless substances and environmentally friendly liquids, but also chemicals, contaminated cooling or heating water, crude oil and similar. To prevent leaks – and thus contamination of the soil and ground water – plastic pipes must meet high material requirements...

Piping systems made of spun glass fibre reinforced polyester resins are mainly used for drinking water and waste water pipes and in irrigation and drainage systems. The pipe diameter can vary between 150 mm and 4200 mm. As the pipes are exposed to high pressure loads during installation, determining the mechanical properties is of central importance. This is done by testing the ring stiffness. Ring stiffness describes the strength behaviour of plastic pipes. Characteristic values are the crown compressive strength according to DIN EN 1228 as well as the compressive and circumferential elongation. All values are determined in both the circumferential and longitudinal directions.

Hegewald & Peschke offers two machines for this test.

The nominal ring stiffness characterises the strength behaviour of plastic pipes in the construction, electrical and water/waste water industries and is subject to European standards.

Styrofoam is particularly light and requires an extremely precise testing method that can handle large quantities, e.g. as part of continuous production. The inspekt table 5kN universal testing machine performs this task unerringly, virtually trouble-free and reliably.

• Branch: metal and plastics industry 

The universal testing machine inspekt 100kN with lateral test room 50kN was constructed for the tensile testing of metals and plastics at high and low temperatures...
