Refrigerator & Freezer Thermal Performance Test Packages

Product Overview

To accurately assess the thermal performance of household refrigerators, freezers, and refrigerator-freezer combinations, freezing load test packages are the globally recognized standard solution for modern testing laboratories and certification bodies. These packages simulate the thermal behavior of real food loads, delivering exceptional durability, cost-effectiveness, and safety for repeated laboratory use.All our test packages are manufactured in strict compliance with the following international standards:
  • IEC 62552: Household refrigerating appliances – Characteristics and test methods
  • AHAM HRF-1-2007: Energy and Internal Volume of Refrigerating Appliances
  • SASO 2664-2007: Saudi Arabian Standard for Household Refrigerators and Freezers
  • AS/NZS 4474.1 (Australian Standard): Performance of household refrigerating appliances
  • AS72-2005: North American Standard for Commercial Refrigerating Appliances

Product Characteristics

  1. Thermal performance is engineered to match that of lean beef, with a controlled freezing point of -1°C for accurate food load simulation.
  1. After filling, each package is immediately sealed with a thin plastic film or equivalent material that enables moderate vapor exchange with the surrounding environment, per standard requirements.
  1. The "M Package" is a 500g test unit with a thermocouple installed at its geometric center for precise temperature measurement, ensuring direct contact between the sensor and the package contents.

Standard Test Packages by Specification

1. IEC 62552 Standard Test Packages

Widely adopted by manufacturers and testing organizations worldwide, including China, this standard defines test packages for household refrigerator performance testing, available in -1°C and -5°C versions.
