The environment in which the paper and paperboard will be used needs to be controlled by air conditioning. An air conditioning system will compensate for the changes in humidity and temperature that occur.
ISO 11093-2 is the second part of the ISO 11093 multi-series standard that focuses on testing of cores for paper and board products. ISO 11093-2 focuses on Standard conditioning and testing atmospheres for paper, board, and pulp. ISO 11093-2 specifies the conditioning atmospheres to be used for conditioning and testing cores.
ISO 11093-2 on the conditioning of paper and board is useful for:
Conditioning defines establishing a moisture equilibrium between the test piece and a conditioning atmosphere of a specified temperature and relative humidity. The moisture equilibrium is required to establish a stable physical state of the cores. Under certain circumstances, conditioning may have to be prolonged until the desired physical state has been attained.
ISO 11093-2 provides you with the standard atmospheres for normal preconditioning, conditioning, and testing of paper and paper products, paperboard, fibreboard, and containers made from them. ISO 11093-2 also specifies procedures for handling these materials in order that they may reach equilibrium with the respective atmosphere.
ISO 11093-2 helps to establish the conditioning atmosphere and method of conditioning paper and board before and during testing.
