This standard defines a generic container format to store a delivered set of documents, including a means to link otherwise disconnected data. In this context, the term document refers to any digital resource that provides information about the built or natural environment, including, but not limited to, any 2D or 3D representation or model, spreadsheet, image or text-based digital resource.

This standard is suitable for all parties dealing with information concerning the built environment, where there is a need to exchange multiple documents and their interrelationships, either as part of the process or as contracted deliverables.  The format is intended to use resources either included in the container (such as documents) or referenced remotely (such as web resources). A key feature is that the container can include information about the relationships between the documents. Relevant use-cases reflect the need for information exchange during the entire life cycle of any built asset and may include, but is not limited to, the handover of

a published bidding package,

required project deliverables at a specific project stage,

shared information as background or for further development, or

published approval packages.

The container format includes a header file and optional link files that define relationships by including references to the documents, or to elements within them. The header file uniquely identifies the container and its contractual or collaborative intention. This information is defined using the RDF and OWL semantic web standards.

The header file, along with any additional RDF/OWL files or resources, forms a suite that may be directly queried by software. Where it includes link references into the content of documents that don’t support standardized querying mechanisms, their resolution may depend on third party interpreters. Alternatively, the link references may be interpreted by the recipient applications, or reviewed interactively by the recipient.

The format can also be used to deliver multiple versions of the same document with the ability to convey the known differences or priority between them.

This document specifies a fire test method and an assessment procedure for determining the contribution of fire protection systems to the fire resistance performance of circular and rectangular steel bars used as tension members.

This document applies to fire protection materials that have already been tested and assessed in accordance with EN 13381‑4 or EN 13381‑8. If testing to EN 13381‑4 or EN 13381‑8 has not been carried out then loaded testing shall be carried out in accordance with Annex B using a minimum length of 2 000 mm.

For other section shapes such as angles, channels and flats, reference should be made to EN 13381‑4 and EN 13381‑8. This document does not include steel or any other cold formed bar used as reinforcement in concrete construction.

For other solid bar geometries such as oval or triangular cross section, these should be subject to a separate test package in accordance with the principles of Clause 5 of this document.

Fire protection performance is determined by testing of unloaded tension members, although additional loaded test evidence may be required for certain product types subject to certain conditions specified in the document.

The method is applicable to all fire protection systems used for the protection of solid bar up to a maximum diameter of 130 mm and includes sprayed fire protection, reactive coatings, cladding protection systems and multi-layer or composite fire protection materials. In the case of rectangular bar, the maximum side length should be limited to 130mm with a maximum aspect ratio of 2:1 against the shorter side length. For dimensions greater than 130mm it is appropriate to use rectangular or circular hollow sections tested and assessed in accordance with EN 13381‑4 and EN 13381‑8 provided they have been tested in the same orientation.

The evaluation is designed to cover a range of thicknesses of the applied fire protection material, a range of steel bar dimensions, a range of specified temperatures and a range of valid fire protection periods.

The test method is applicable to fire protection systems which are intimately in contact with the bar, or which include an airspace between the bar and the protection system as given in EN 13381‑4.

This document also provides the assessment procedure, which prescribes the analysis of the test data and gives guidance on the procedures to undertake interpolation.

This document caters for testing in both vertical and horizontal orientations. Results from horizontally orientated bar may be applied to any orientation, whilst results from vertically orientated bar should only be used for horizontal bars when the data has been corrected in accordance with Annex C.

This document gives the fire test procedures, carried out to provide data on the thermal characteristics of the fire protection system, when exposed to the standard temperature/time curve specified in Clause 5.1.1 of EN 1363‑1.

The assessment procedure is used to establish:

a)     on the basis of data derived from testing steel bar, any practical constraints on the use of the fire protection system under fire test conditions (the physical performance);

b)    on the basis of the temperature data derived from testing steel bar the thermal properties of the fire protection system (the thermal performance).

The limits of applicability of the results of the assessment arising from the fire test are defined together with application of the results to different steel types and sizes over the range of thicknesses of the applied fire protection system tested.

This document specifies the requirements and test methods for flue dampers that are used as components, carrying flue gas, in order to limit the flow in a chimney.

Flue dampers may be manually adjusted, sited in connecting flue pipes or chimneys, in order to reduce the burning rate (solid fuel stoves/fireplaces) or to work as a shut-off slide preventing back flow of soot during cleaning of the chimney, or mechanically driven for reducing/closing the flue, in order to reduce the stand-by losses or to prevent the backflow of the flue gas e.g. in case of multi-served chimneys.

This document covers only flue dampers incorporated in a housing and installed inside a building.

Flue dampers already tested together with system chimney products or other chimney components, e.g. flue liners, connecting flue pipes, are not covered by this document.

This document also specifies the requirements for marking, manufacturers’ instruction, product information, Assessment and Verification of Constancy of Performance (AVCP), cleaning and maintenance.
