In the context of this document, algae are a functional group that include microalgae, macroalgae, cyanobacteria and Labyrinthulomycetes.
As algae and their production processes are so diverse, this document does not define a specific sampling program and/or a specific sampling protocol. Instead, this document specifies the aspects that can be considered when defining its own sampling program and protocol.
This document describes when, where and how to draw a representative sample. For guidance on sample preparation of dry and wet samples of micro- and macroalgae, and algae products, please refer to EN 17605.
This document is to be used for the collection of samples for lot characterization for commercial or legal/regulatory purposes. However, this document can also be used for any type of sampling of algae, including samples for quality control during production.

This document specifies a test method simulating practical conditions for establishing whether a product for hygienic handrub reduces the release of virus contamination on hands when rubbed onto the artificially contaminated hands of volunteers.
NOTE 1   Attention is drawn to the fact that tests on human volunteers are the subject of legal provisions in certain European countries/regions.
This document is applicable to products for hygienic handrub for use in areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example:
-   in hospitals, in community medical facilities and in dental institutions;
-   in clinics of schools, of kindergartens and of nursing homes;
and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patient.
EN 14885 specifies in detail the relationship of the various tests to one another and to “use recommendations”.
NOTE 2   This method corresponds to a phase 2, step 2 test.
