New Test Method for Assessing Carpet Wetness after cleaning with a Wet Extraction Cleaning System

1. Scope

This test method provides only a laboratory test for determining the relative carpet wetness after cleaning with a wet extraction cleaning system when tested under standard conditions. This method assesses the wetness of carpets by measuring the weight (mass) of remaining moisture in carpet after performing a standard cleaning cycle, and then calculating the mass density of the wetted area created visually by the wet extraction cleaner. This method does not quantify drying time but provides a indication of comparative drying time for differentiating wet extraction cleaners. This test method applies only to the cleaning of virgin, unsoiled, untreated carpet. This test method is applicable to types of upright, canister, and combination wet extraction cleaners and their recommended chemical cleaning formulas intended for cleaning carpets as a primary or secondary function. This test method excludes pre-spray systems or pre-spray treatments.

Rationale

There are two major consumer performance assessments of wet carpet cleaning appliances (i.e. Extractors), those being carpet cleaning performance, and carpet cleaning wetness. Carpet wetness is an indirect indication of the cleaner's suction performance and carpet drying time, both of which are meaningful to the user of such products. The F11.35 Subcommittee has developed a method for assessing cleaning performance of these products but currently has not established an industry standard for assessing carpet wetness.

The title and scope are in draft form and are under development within this ASTM Committee.
