ISO 22982-2:2021 pdf download.Transport Packaging - Temperature controlled transport packages for parcel shipping
1 Scope
This document specifies the test methods of temperature-controlled packages for parcel shipping.Tests include physical, thermal conductivity and insulation performances of transport packages that use insulation for the purpose of blocking thermal conduction between the inside and the outside of a product package that need temperature control.

4.1.1 Sampling
All tests shall be performed with new and unused package and product. Tests shall not be performed within 72 h after the production of the packages. Packages subject for testing shall be randomly selected. If this is not possible, packages as identical as possible to actual packages shall be used and addressed in the report with the agreement of the stakeholders.
4.1.2 Test sample
Test samples used for the tests shall include an actual product. If it is not available, a dummy product having characteristics as identical as possible may be used. Characteristics include physical and thermal properties, composition and physical status (e.g. liquid, powder, solids). A product may be packaged with primary package or unpackaged.
Outside dimension, weight, and total weight including the product shall be measured and recorded prior to testing according to the mean value obtained from five sample measurements. If a refrigerant or temperature stabilizer is used to maintain the temperature of the package and product, the characteristics and performance of this refrigerant or temperature stabilizer shall be recorded in the report.
4.3.1.1 Outside atmosphere temperature
An environmental chamber that can consistently maintain the determined outside temperature shall be used. The environmental chamber shall be pre-cooled or pre-heated to the intended temperature condition before the test. Air velocity of the chamber should be uniform and is recommended to be controlled between 0,1 m/s and 2 m/s.
Depending on the circumstances, the outside atmosphere temperature shall be determined either by temperature profiles collected from recorded data or pre-determined temperatures set by stakeholders.ISO 22982-2 pdf download.
