1. Our test packages come in the form of rectangular parallelepipeds with specific dimensions and mass as outlined below:

2. Standard M Test Packages According to IEC62552

These test packages are equipped with thermocouples or pre-embedded copper tubes for temperature measurement. The dimensions are as follows:

Composition

The packages shall consist of the following.

a)A suitable filling material containing, per 1 000 g:

--230 g of oxyethylmethylcellulose;

--764.2 g of water;

--5 g of sodium chloride;

--0,8 g of 6-chloro-m-cresol.

The freezing point of this material is - 1 °C (its thermal characteristics correspond to those of lean beef)

b) The following alternative composition of test packages with a freezing point near - 5 °C may be used:

--232 g of oxyethyimethylcellulose

--725 g of water;

--43 g of sodium chloride;

--0.6 g of 6-chloro-m-cresol.

In case of dispute, the composition of test package a) shall be used as the reference test package.For the measurement of chill compartments, only test package b), with a freezing point of - 5 °C, shall be

used.

For disputes, the standard composition is used as the reference test package.

Custom Solutions:

We offer custom-made test packages tailored to your specific needs, including copper pillars and plugs for thermocouple wire connections.

Regular Maintenance of filled pacakge:

1. Need at below zero temperature condition when long storing, the optimum temporary is -18℃.

2. Thawing: Should be natural thawed at room temperature, don’t use such as microwave ovens, electromagnetic ovens to thaw.

3. Freezing: Beware of deformation when test package begin to freeze. Need repair timely if they have been deformed. The correct way is freezing in batches, when lower test package has completely freezing, add another one above it. This can prevents the lowermost test package by extrusion.

4. Seal: Keeping in sealed condition, once package is damaged should be repaired or discarded immediately, otherwise evaporation of water will affect the quality of test package.
