About This Item

 

Full Description

1. Purpose and Scope

1.1 This test method is for the evaluation of the degree of anti-house dust mite activity in a long-term testing environment for textiles treated at the manufacturing level for this purpose.

2. Principle

2.1 Test and control specimens are inoculated with the test organism and nutrients. After six weeks of incubation, sufficient time for mite colonies to flourish under optimal conditions, the dust mites are recovered from the specimens by heat extraction. Results are expressed as percent reduction on the treated sample versus the untreated control.
