Test criteria

This long-term test evaluates the acaricidal efficacy (mite killing effect) of finishings on the development of a house dust mite population.

The acaricidal efficacy of a textile sample and the finish against house dust mites is performed following the French standard NF G39-011. For that purpose, house dust mites (Dermatophagoides pteronyssinus) are applied on the sample material and the controls. After one week and six weeks the growth of the mite population is quantified.

In the case of three-dimensional test specimens, which do not allow a counting of the mites due to their construction, the allergen content (major allergen Der p 1) is determined after ­­6 weeks.
