the product under normal conditions of use and can provide useful
feedback on safety, efficacy and acceptability (in both practical and
aesthetic terms) of the product and packaging. In-use testing can be
conducted on any consumer product and many detailed aspects of the
test will be specific to the particular type of product under study.
The following services are provided:
