Normes applicables
The tester complies with international protocols:
TAPPI: T 441 om-21 (Water Absorptiveness)
ISO: ISO 535 (Paper/board), ISO 187 (Board)
GB/T: GB/T 1540 (Paper/board), GB/T 461.1 (Board)
| Paramètres | Spécification |
|---|---|
| Test Area | 100 cm² (Standard), Adjustable |
| Contact Time | 60/120 seconds (Programmable) |
| Water Volume | 250mL (Standard Reservoir) |
| Measurement Range | 0-500 g/m² |
| Accuracy | ±1% (Full Scale) |
The tester uses a cylindrical head to deliver controlled water volume to a flat sample. After a set time, the absorbed water mass is measured and divided by the test area to compute absorption rate (g/m²).
Sample Prep: Cut a 125mm diameter sample.
Water Application: Place the head on the sample, releasing water for 60/120 seconds.
Result Calculation: Weigh the absorbed water and compute:
Absorption Rate = Absorbed Water (g) / Test Area (m²)
Used in R&D and QA labs, the tester ensures materials meet absorbency targets for tissues, food packaging, and medical products. Compliance with TAPPI/ISO standards ensures reliable data for process control and material development.
This guide equips users with technical insights to select and utilize water absorption testers, ensuring precise measurements and material optimization.
