This European Standard specifies the principles of design, sizing, installation, identification, commissioning and maintenance of greywater systems with the purpose of use of greywater on-site. It applies preferably for the use of treated greywater for: - WC flushing; - garden watering; - laundry; - cleaning purposes. This European Standard also specifies the minimum requirements for greywater systems. Excluded from the scope of this European Standard are: - the use as drinking water and for food preparation; - the use for personal hygiene purposes; - direct reuse systems for external use e. g. garden watering; - product design for specific system components; - industrial effluents; - heat recovery and cooling demands. NOTE Conformity with this European Standard does not exempt from compliance with the obligations arising from local or national regulations.

This European Standard specifies safety requirements for floating landing stages and floating bridges for passenger transport and their equipment. Requirements for facilities for supply and waste disposals for vessels using these floating landing stages are not covered by this Standard. This European Standard is not applicable to: - floating landing stages for motor vehicle traffic; - floating landing stages for recreational craft and inland navigation craft that are not vessels, e.g. floating equipment; - more severe requirements for floating landing stages used for the transhipment of dangerous goods; - any landing stages required between vessel and floating landing stage; - specialized floating structures which are not used for passenger traffic or the berthing of vessels.

This European Standard specifies a procedure for the determination of the particle size distribution of the aggregates of bituminous mixtures by sieving. The test is applicable to aggregates recovered after binder extraction in accordance with EN 12697-1 or EN 12697-39. The applicability of this European Standard is described in the product standards for bituminous mixtures. NOTE Fibres, solid (non-soluble during extraction) additives and (some) binder modifiers influence the test result.
