9、struction is allowed to dwell in a constant tempera-ture and humidity environment for 30 min.The construction isthen mounted vertically.A standard mass of 500 g 1.1 lb isattached to the pressure sensitive article and allowed to actuntil the construction separates or until 3000 min elapse.Ifthere is
10、no separation after 3000 min,the test is repeated on afresh specimen with a mass of 1000 g 2.2 lb and allowed toact until separation occurs or until 3000 min elapse.If noseparation occurs,perform Procedure C of Test MethodD3654/D3654M for shear holding power to stainless steel at49C 120F.The test re
