Testing Standard:
TAPPI T432 Water Absorbency of Bibulous Papers
Standard Number
TAPPI T432
Standard Title
Water Absorbency of Bibulous Papers, Test Method
Overview:
TAPPI T432 Test Method is used to evaluate the material’s rate of water absorption. This method applies to most bibulous materials such as tissues, towels, and blotter papers. Purple Diamond Testing offers TAPPI T432 Water Absorbency of Bibulous Papers as part of our packaging compliance and validation services.
Rationale:
TAPPI T432 – Water Absorbency of Bibulous Papers. The amount of moisture in paper materials affects the overall physical strength, porosity, and end useability. This method can be ideal when comparing different materials or verifying a material is within a specified range of acceptance. A set volume of water is applied to the material and the time it takes to be absorbed is recorded.
Key Points:
- Indicates potential issues due to absorbency
- Utilize this test method to ensure quality control
- Verifies specifications as stated by the manufacturer
