SEALING OF SEAMS AND HYDROSTATIC TEST REQUIREMENTS IN SPECIFICATIONS

Abstract

Hydrostatic tests are used to determine the degree of waterproofness of water-repellent-treated fabrics, coated fabrics and items made therefrom. Water-repellent-treated fabrics and seams in coated fabrics are usually evaluated by the Suter test which measures the pressure in inches of water, while the continuity of coating in coated fabrics is measured by the Mullen test which utilizes pressures from 20 to 400 pounds per square inch. The specification requirements were adopted, based on numerous laboratory reports and standard commercial practices. Included in the report are lists of specifications using the tests, laboratory reports correlating rainroom tests with laboratory data, and reports from commercial outfits requiring the tests. The validity of the tests is considered to have been established.
