'Tylose' Test Packs

Standard testing of refrigerated appliances requires the use of test packs to simulate loading with food. RD&T manufacture packs that are suitable for retail/commercial, professional and domestic refrigerated appliance testing. These are manufactured from a cellulose gel (tylose) and have tight constraints on size and weight, with tolerances which vary slightly depending on the standard being used. 

For retail/commercial cabinet testing under EN23953 and professional/catering cabinet testing under EN16825, these tolerances are as follows:

  • ± 2 mm for linear dimensions 25 to 50 mm
  • ± 4 mm for linear dimensions 100 to 200 mm
  • ± 2 % for mass

For domestic appliance testing under EN62552, slightly tighter tolerances are applied:

  • ± 2 mm for linear dimensions 25 to 50 mm
  • ± 3 mm for linear dimensions 100 to 200 mm
  • ± 2 % for mass

The packs are produced in robust High Impact Polystyrene, which avoids squashing and deformation during repeated use.

Thermocouple temperature sensors or other probe types such as thermistors/PRT sensors can also be supplied either separately or inserted into measurement M-packs.

If you would prefer not to buy test packs, we also provide a service where customers can rent test packs.
