Foam Humid Ageing Chamber for Compression Set Testing

Programmable humidity chamber that conditions foam specimens at 50 to 90 deg C and up to 95 percent RH for humid ageing tests. Used by automotive seating and mattress foam suppliers under ASTM D3574 Test J and ISO 2440.

Specification

Foam specimens are aged under controlled temperature and relative humidity, then re-tested for load and compression change. The chamber has a stainless steel interior and steam humidification for fast recovery. It simplifies repeated humid ageing and steam autoclave simulations.

Features

• Temperature range ambient +10 to 100 deg C
• RH control 30 to 95 percent
• Stainless steel 304 chamber with viewing window
• PID microprocessor controller with timer
• Over temperature cut off and water level protection
