Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

The scope of this document is the forward flow of E-Commerce items. Starting point is arrival at a lo-gistic service provider, end point is the final delivery, or at least the attempt to final delivery.

The European Commission will in its project “VAT in the digital age” mandate that VAT reporting on intra-EU transactions is performed in near real time and based on EN 16931. This document defines the impact of this legislation on the various deliverables of CEN/TC 434, with a focus on the subset to be sent to tax authorities and how EN 16931-1 will need to be changed.

As the subset message is not an invoice, but a VAT report, it is not regarded as a Core Invoice Usage Specification (CIUS). The subset therefore needs not to obey the rules for developing a CIUS. For example, not all mandatory elements in the invoice need to be part of the subset.

For such use blackplate is normally coated but can be used uncoated for some fatty or dry products.
The main examples of use are:
-   tinplate and electrolytic chromium/chromium oxide coated steel for the manufacture of food and beverage cans ;
-    cans for conditioning foodstuffs (sugar, tea, cake, chocolate, pasta, etc.) ;

This document specifies a method for the conditioning of bitumen or bituminous binders in order to provide for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder simulating the hardening which most bituminous binders undergo during mixing in an asphalt mixing plant. The method is referred to as RTFOT - Rolling Thin Film Oven Test.
The method described is applicable to paving grade bitumen. The method described is also applicable to other bituminous binders considering that the reference temperature can result in excessive hardening that does not resemble real conditions during mixing at the plant. It is possible that the method does not represent the hardening that occurs during mixing bitumen used for warm mix asphalt.
The method described is not applicable to those binders having a viscosity at the tested temperature not allowing to provide a moving film. In some cases, it is possible that the test sample creeps out of the glass container and flows on the heating elements of the oven during testing.
The method described is not applicable to binders with volatiles components present. In case of cutback bitumen or bituminous emulsion, the described procedure is only applicable after being stabilized, e.g. in accordance with EN 13074-2 [9].
