Standard Title
Practice for Conditioning Paper and Paper Products
Overview for ASTM D685:
Rationale for ASTM D685:
ASTM D685 – Standard Practice for Conditioning Paper and Paper Products. This practice is essential for consistency in test results when evaluating materials regardless of location or timing. The humidity of paper directly affects the physical performance. By conditioning paper to the standard atmospheric conditions, consistent, repeatable test results can be obtained.
For this test method, there is a pre-conditioning requirement. This is important because physical properties of a sample at 50% relative humidity depend upon whether the sample is brought to 50% from a higher or lower relative humidity. Purple Diamond has a whole resource center for conditioning. The conditioning and testing atmospheres are important because both temperature and humidity have significant effects on the physical properties of paper and board.Â
This standard is for lack of a better word, technically, identical to TAPPI T402. The method is applied in order to define the standard conditioning, normal preconditioning, conditioning, and testing of paper and paper products, paperboard, fiberboard, and containers made from those sorts of products.Â
Key Points:
- Optimize costs by mitigating damages accrued through transit
- Validates material selection during box design
- Verifies the physical performance of materials used to withstand conditions like humidity
- Yields consistent test results
