ISO 2233 Conditioning for Testing
ISO 2233 specifies the conditioning of transport packages and unit loads. As an ISTA and ISO 17025 certified lab, we realize the importance of ISO 2233 testing. Meeting the ISO 2233 conditioning requirements can be difficult. Keystone Compliance understands the challenges and guides companies through the process.
Keystone creates an accurate test plan to eliminate expensive over-testing. We provide comprehensive reports shortly after completion of the testing. When packages do not meet the requirements, we assist with finding solutions. Keystone takes a consultative approach throughout the entire test program.
Summary of ISO 2233 Conditioning for Unit Loads
As mentioned above, this ISO package compliance test specifies the conditioning of complete, filled transport packages and unit loads. For the purpose of this international standard, the test specimen is defined as a complete filled transport load.
Scope of ISO 2233 Conditioning of Complete, Filled Transport Packages
First, temperature and relative humidity conditions are selected. These are based on the most appropriate transport and storage functions of the test specimen being selected.
The test specimen is placed within the working space of the conditioning chamber. Next, the specimen is exposed to the specified conditions for a minimum period selected from 4h, 8h, 16h, 24h, 48h, or 72h or from 1 to 4 weeks.
When the test specimen is constructed of materials, such as fiberboard, it may be necessary to pre-dry the specimen before conditioning. This is done by the test specimen being placed in the drying chamber for a minimum period of 24 hours.
Significance of ISO 2233 Transport Loads
One or more conditions in the table below must be selected. For conditions 1, 2, 3 and 10, the maximum permissible temperature shall be ± 3 degrees Celsius. For all other conditions, the maximum temperature difference is ± 2 degrees Celsius.
Some apparatus for the conditioning of unit loads include:
Conditioning Chamber – Having a working space the temperature and humidity of which is continuously recorded. It may also be maintained at the specified conditions within the control tolerances.
The working space is that of a conditioning chamber within which the specified controlled conditions are maintained. The boundaries of this space are specified for each chamber.
Drying Chamber – If necessary, to reduce the moisture content of certain test specimens below that which will be attained by conditioning, this chamber is used.
Measuring and recording apparatus – Sufficiently sensitive and stable to allow measurement of temperature to an accuracy of 0,1 degrees Celsius and relative humidity of 1%.
For the purposes of this international package integrity standard, the record is deemed continuous if the period between individual readings is not greater than 5 min.
The test report on conditioning is completed with information such as impact tests, stacking tests and vibration tests. The test report also includes information such as:
- A reference to this international standard.
- The details of any pre-drying.
- The conditions and time used for conditioning.
- The temperature and relative humidity of the test area at the time of test.
- Any deviation from this international standard.
