This document specifies the composition of the base steel used for the production of tinplate for use in direct contact with foodstuffs or products for human and animal consumption as well as the composition of tin used to coat it. Tinplate can be produced with or without an organic coating.

The main examples of use are:

—    drinks cans,

—    food cans,

—    packaging of dry foods,

—    aerosol cans.

The material is chosen in accordance with the conditions for its use.

This document does not apply to categories of steel other than steel for packaging intended for use in contact with foodstuffs, products or beverages for human or animal consumption.

This document covers hinged and pivoted steel (any kind) and aluminium based framed, glazed doorsets or openable windows. Throughout this document, the term “doorset” will be used to cover both doorsets and door assemblies. It prescribes the methodology for extending the application of test results obtained from fire resistance test(s) conducted in accordance with EN 1634-1.

Subject to the completion of the appropriate test or tests selected from those identified in Clause 4, the extended application can cover all or some of the following examples:

—    integrity (E), integrity & radiation (EW) or integrity & insulation (EI1 or EI2) classification,

—    glazed elements including vision panels and framed glazed doorsets,

—    air transfer grilles (louvres and/or vents),

—    side, transom or over panels,

—    items of building hardware,

—    decorative and protective finishes,

—    intumescent seals and non-intumescent (smoke, draught or acoustic) seals,

—    alternative supporting construction(s).

This document does not cover horizontal doorsets.

The effect on the Classification ‘C’ for the doorsets following an extended application process is not addressed in this document.

Plastic waterproofing sheets generate plastic waste at different stages: production, construction process, use and end of life.

This document defines the origin of recyclate made from pre-consumer material and post-consumer material as it is used in new products. These new products can be plastic waterproofing sheets, other sheets, other construction products or other products.

It specifies terms and definitions.

It gives guidance for assessing the recyclates intended for use in the production of new products.

NOTE          This document is suitable for products with similar content like: swimming pool membranes, geosynthetic barriers, garden ponds, walk-ways, protection membranes, prefabricated pieces. The design for recycling of packaging, including the recycling itself, is defined in the CEN TC 261 Packaging.
