Thermal aging of plastics in heating cabinets
Reliable test methods according to DIN EN ISO, ASTM, and UL

Accelerated thermal aging of plastics is a key test method for determining the durability and material resistance of new products. With our heating cabinets, you can precisely simulate thermal aging—in accordance with standards and reproducibly.

Our heating cabinets ensure high spatial temperature accuracy and compliance with a defined air exchange rate – basic requirements for standard-compliant testing. They meet the specifications of important international standards, such as:

DIN EN 60216-4-1: Testing of electrical insulating materials with regard to long-term thermal properties (temperature range from 80 °C to 500 °C)
DIN 53508: Aging tests on rubber and elastomers (70–250 °C, forced or natural convection)
ISO 188: Aging tests on vulcanized or thermoplastic rubber (100–300 °C, defined air exchange rates)
DIN EN 60811-401: Test methods for non-metallic materials, such as cables, insulated wires, and fiber optic cables (up to 300 °C, natural or forced convection)

Air exchange measurement for standard-compliant test conditions

In addition to our high-performance heating cabinets, we also offer air exchange measurement in accordance with ASTM D5374-13. This includes defining the ambient conditions, precisely determining the air exchange rate, and providing complete documentation in a standard-compliant report. This ensures that your test chambers reliably meet the requirements for thermal aging tests according to international standards – even with existing heating chambers.

Areas of application in research and industry

Our heating cabinets are used in numerous industries, such as the automotive industry (testing of cables, seals, and components), electrical engineering (thermal aging of insulating materials), medical and pharmaceutical technology, and aerospace. They deliver reliable test results wherever materials have to withstand high temperatures and constant air exchange over long periods of time
