（HBA 24）HEATING BLOCKS FOR ACCELERATED AGING

The HBA™   is used to artificially accelerated the aging process of energetic materials by way of protracted storage of the sample at high temperatures. Under normal conditions, the rate of decomposition is slow . Consequently, accelerated aging is used to predict the lifetime . The aging period may last for weeks to months with temperatures usually reaching between 50 °C to 90 °C.

DESCRIPTION

The HBA™ is comprised of a heavy, aluminum heating block with 24 test tube holder holes. Each test tube is covered with a glass lid. The test samples are placed into the heating block. The temperature of the block is administered by a control unit which is comprised of an operational controller and a limit controller. The limit controller operates an independent alarm circuit which halts the heating process if temperatures were to accidentally increase above specified safety limits. Calibrated mercury thermometers or calibrated digital thermometers may be used to correct and control the temperature of the heating block.

The HBA’s™ standard heavy, aluminum heating block can hold and measure up to 24 samples (with individual time exposures for each one).   Heating blocks with a different desired number of holes are available on request.
