Bally Waterproofness Test Method
1. A rectangular test specimen is bent partly round, and secured between, two cylindrical clamps so as to form a trough.
2. The trough is then immersed in water and the clamps oscillate at a constant speed so that the specimen is repeatedly flexed.
3. The time taken for water penetration through the test specimen to occur is recorded.
4. The mass of water absorbed by, and transmitted through, the test specimen can also be measured.
