Scope

This test method should provide a consistent approach both in terms of test insects and test procedures for the gathering of efficacy data for pediculicides.

Data collection in this manner should be suitable for product development and comparison. In addition, it should be suitable for review by regulatory agencies.

1.1 This test method determines the effectiveness of pediculicidal materials in liquid, gel, or cream form, against the adult human louse, Pediculus humanus humanus Linnaeus, the surrogate subspecies for the human head louse (P.h. capitis). (Only gels or creams that liquefy at 32°C (90°F) can be tested).

1.2 This test method is for the use of those wishing to develop efficacy data, or to compare formulations for head louse control.

1.3 This test method consists of five replicates for a statistical comparison of formulations.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
