Standard Practice for Pre-Stressing Terminal Point-of-Use Water Filters before Testing by Test Method F838

Importancia y uso:

5.1 This practice has been developed to simulate the stress encountered by terminal point-of-use filters under a range of real-world use conditions with emphasis on thermal and pressure swings. Two parts, A and B, are intended to account for more frequent, less extreme use conditions and less frequent, more extreme use conditions, respectively. The purpose of pre-stressing the filters before testing by Test Method F838 is to demonstrate the ability of the filters to retain bacteria as determined by Test Method F838 after exposure to a series of temperature and pressure swings representative of those that may be encountered under actual use conditions.

5.2 This practice is not intended to account for effects on filter performance attributable to differences in the quality of the water being filtered that may be encountered under actual use conditions.

5.3 This practice is not intended to simulate the very extreme stress associated with systemic remedial procedures, such as thermal or chemical shock, sometimes implemented in premise plumbing systems.
