WebDesigners must account for equipment leakage separately from duct leakage allowances as they evaluate system leakage. SMACNA encourages designers to specify equipment leakage control and to rely on prescriptive sealing of ductwork as measures that will normally lead to effective control of leakage without the need for extensive leakage testing. WebKey applications for holiday testing include finding discontinuities in thin coating films , piping and structures, storage tank interiors, and rubberized waterproofing on concrete. Industries that use holiday testing include oil/gas, transportation, construction, tank manufacturers, and coatings/inks/adhesives suppliers.
