[Paper and Board Absorbency Test] JIS P 8140 Cobb Method
Please leave the water absorption test of paper and board to JBL.
This is a test to measure the water absorption of non-water-absorbent paper and board when one side is in contact with water for a certain period of time. The test is conducted using equipment specified in JIS P 8140. It is also possible to cut the test samples using our company's sample cutter. ▼ For more details, please download the PDF document. (Recommended) ▼ If you need assistance urgently, please contact us using the 'Contact Us' link below.
basic information
The water absorption capacity (Cobb value) is calculated by converting the mass of water absorbed by paper or board under specified conditions to a per square meter basis. After conducting temperature and humidity control for 24 hours, a water immersion test using distilled water or similar is performed, and the weight of the test specimen is measured to an accuracy of 1 mg. JIS P 8140 is a Japanese Industrial Standard created based on ISO 535 (Paper and board - Determination of water absorptiveness - Cobb method).
