Standard Number
TAPPI T432
Standard Title
Water Absorbency of Bibulous Papers, Test Method
Overview of TAPPI T432 Water Absorbency of Paper:
TAPPI T432 Test Method applies to most bibulous materials such as tissues, towels, and blotter paper. TAPPI T432 is a test method developed by the Technical Association of the Pulp and Paper Industry (TAPPI) to measure the water absorbency of paper. The test involves placing a piece of paper with a known area and mass in contact with a quantity of water, and allowing the water to be absorbed by the paper for a specified period of time. The mass of the wet paper is then measured, and the water absorbency is calculated as the amount of water absorbed per unit area of paper. The test is often used to evaluate the performance of paper products for applications where they will be exposed to moisture or water, such as in packaging or printing applications. Purple Diamond Testing offers TAPPI T432 Water Absorbency of Bibulous Papers as part of our packaging compliance and validation services.
Rationale for TAPPI T432 Water Absorbency of Paper:
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 varied 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
