5 Test methods
5.1 Material properties
Test methods for material properties are given in the appropriate material standards as detailed in 4.2.
5.2 Structural properties
The performance of the product under distributed load shall be determined in accordance with 4.3.1 and 4.3.2.
The performance of the product under concentrated load shall be stated by the manufacturer with reference to the method used to determine the results.
NOTE Safety under the load from people and the risk of permanent deformation is dependent on many factors, such as slope of roof, method of installation, etc.
Methods for testing the strength under concentrated load are not yet available on a European level. Information on national standards is given in Annex E. Rules for installation are given in some national codes.
6 Designation
Products covered by this standard shall be designated as follows:
— type of product according to the designation of the manufacturer;
— European standard number;
— nominal thickness and thickness class (see 4.3.3.2); material (designation of material) (see 3.5 and 4.2);
— length and, in addition for tiles, the length of the step.
EXAMPLE
Profile 45, thickness 0,7 mm, class 1;
length 4200 mm; 5350GD+ZA 255

7 Marking, labelling and packaging
7.1 Marking and labelling
At least the following information shall be attached to every pack, bundle or delivery unit:
— name or registered identification of the manufacturer; designation of the product (see clause 6);
— order or manufacturing batch number; dimension and quantity;
gross mass (kg).
7.2 Packaging and special ordering conditions
The packaging requirements and any special requirements to take account of particular conditions shall be agreed between manufacturer and purchaser at the time of ordering.
7.3 Transport, storage and handling
Any instructions regarding transport, storage and handling shall be clearly visible on the package.
NOTE I The packages should be supported by means of battens providing sufficient space to permit good ventilation while avoiding any permanent deformation of the sheets. The packages should be inclined in order to promote drainage.
The packages should be stored under a covered warehouse or under a cover made from tarpaulin over a frame. The frame should allow sufficient space between tarpaulin and packages to allow air to circulate.
NOTE 2 Moisture, in particular condensation inside packages, can lead to the formation of stains (e.g. white rust on zinc and zinc-alloy coatings and black marks on aluminium coatings). If there is prolonged contact with moisture, this can cause damage to the corrosion protection of coatings.
During transportation, dark spots can appear on the hot-dip metallic coated surfaces as a result of friction when packing allows movement between neighbouring surfaces.
NOTE 3 If severe service conditions are expected during transportation, storage or processing, the product can be supplied with an additional protection of a temporary, strippable film, wax or oil.
Type, thickness, adhesion properties, formability, tear strength and light fastness should be taken into consideration when choosing protective films. All protective films can be exposed to outdoor weathering for only a limited period without deterioration.
