This part of ISO 9705 specifies the test method to evaluate the reaction of wall and ceiling products to
fire when installed at the surface of a small room and exposed directly to a specified ignition source.
The test represents a fire scenario, which starts under well-ventilated conditions in a corner of a
specified room with a single open doorway.
Tests performed in accordance with the method specified in this part of ISO 9705 provide data
for the early stages of a fire from ignition up to flashover. The method does not evaluate the fire
resistance of products.
The method is not intended to evaluate floor coverings. This method is not suitable for sandwich
panel building systems, pipe insulation and façades for which specific ISO standards (i.e. ISO 13784,
ISO 20632 and ISO 13785, respectively) are available.

This part of EN 1364 specifies a method for determining the fire resistance of ceilings, which in themselves possess fire resistance independent of any building element above them. This European Standard is used in conjunction with EN 1363-1.
The method is applicable to ceilings, which are either suspended by hangers or fixed directly to a supporting frame or construction, and to self-supporting ceilings.
Within this test method, the ceiling is exposed to fire, with the exposure being applied either:
a)   from below the ceiling, or
b)   from above the ceiling to simulate fire within the cavity above the ceiling.
The contribution to fire resistance which a suspended ceiling might provide as a protective membrane to loadbearing elements is determined using the procedure given in EN 13381-1. The fire resistance of loadbearing floors in conjunction with a suspended ceiling can also be assessed by using tests according to EN 1365-2.

This European Standard constitutes a frame standard for the design of timber stairs as well as wood and wood-based components used in stairs by calculation methods. Some calculation methods can be derived from testing results, for example CEN/TS 15680. This document specifies the design and the requirements for materials and components to be used in these calculation methods. It may be complemented by national application documents based on this European Standard.
This European Standard applies to coated and uncoated components. This document covers load-bearing components such as strings, treads, risers, posts and guardrails. Requirements for a timber stair are defined in the product standard, EN 15644. This document does not cover stairs that contribute to the overall stability of the works or the strength of the structure.
This European Standard is valid for the verification of mechanical performance characteristics, usability and load-bearing capacity and their related durability. Other requirements, e.g. requirements for acoustic properties, are not covered by this European Standard.
For the design, calculation and determination of not solely resting actions, additional requirements need to be taken into account (to be checked).
For the dimensioning with special reference to resistance to fire and earthquake/seismic action, additional requirements may be taken into account.
Without further verification, the methods in this European Standard are valid for different types of stair structures and their components, as illustrated in Figure 1:

This standard sets up a laboratory measurement method to determine the impact noise reduction of a floor covering when laid on a standard concrete floor mock-up and excited by a standard tapping machine. The method is restricted to floorings, which transmit impact sound mainly "locally" into the floor, i.e. through the area close to the points of excitation, so that the size of the flooring specimen does not have an influence on the results. Examples for such floors are carpets, PVC floorings, laminate floorings (lightweight floating floors, parquet floorings?) and the like.  The results only provide information about the noise radiated. A subjective classification of the quality of the floor coverings is not intended.  The method is kept as close as possible to ISO 140-8 and yields similar results within the range of application.  This standard provides the measurement method. Product test codes may contain further requirements concerning the specimens, such as temperature range, the number of test specimens or special mounting conditions.

This European Standard deals with the requirements and the basic performance criteria and specifies minimum values where appropriate for precast hollow core slabs made of prestressed or reinforced normal weight concrete according to EN 1992-1-1:2004.
This European Standard covers terminology, performance criteria, tolerances, relevant physical properties, special test methods, and special aspects of transport and erection.
Hollow core elements are used in floors, roofs, walls and similar applications. In this European Standard the material properties and other requirements for floors and roofs are dealt with; for special use in walls and other applications, see the relevant product standards for possible additional requirements.
The elements have lateral edges with a grooved profile in order to make a shear key to transfer shear through joints contiguous elements. For diaphragm action the joints have to function as horizontal shear joints.
To improve this action vertical grooves may be provided.
The elements are manufactured in factories by extrusion, slipforming or mouldcasting. Fitting slabs (narrowed slab elements) and recesses to the hollow core slabs can be made during production or afterwards. Hollow core slabs can have provisions for thermal activation, heating, cooling, sound insulation, etc. Due to these provisions, the concrete temperature remains in it’s natural range.
This European Standard also deals with solid slab elements used in conjunction with hollow core slabs and manufactured by extrusion, slipforming or mouldcasting, equivalent to the manufacturing of hollow core slabs. These solid slabs have the same overall cross-section as hollow core slabs, however without hollow cores.
The application of the standard is limited for prestressed elements to a maximum depth of 500 mm and for reinforced elements to a maximum depth of 300 mm.
For both types, the maximum width without transverse reinforcement is limited to 1 200 mm and with transverse reinforcement to 2 400 mm.
The elements may be used in composite action with an in situ structural topping cast on site.
The applications considered are floors and roofs of buildings, including areas for vehicles in the category F and G of EN 1991-1-1 which are not subjected to fatigue loading. For building in seismic zones additional provisions are given in EN 1998-1.
This European Standard does not deal with complementary matters. E.g. the slabs should not be used in roofs without additional protection against water penetration.

This standard gives specifications for materials, production, properties, requirements and methods of testing for precast concrete monolithic stairs, and for precast concrete elements (e.g. individual steps) used to make reinforced and/or prestressed concrete stairs.
This standard is applicable to structural stairs for indoor or outdoor use.
This standard covers precast concrete stairs and associated landings of monolithic design or constructed from individual steps supported by beams or columns. Supporting elements may include in situ concrete.
This standard covers terminology, performance criteria, verification methods, tolerances, relevant physical properties, special test methods and specific aspects of transport, erection and connection.
Geometrical properties related to functionality of stairs are not covered by this standard and can be found in National regulations or local practice.
Precast concrete stairs are classified into two main product families :
?   monolithic stairs constructed from precast concrete components consisting of flights, landings or a combination of these. They may include vertical supporting elements ;
?   stairs constructed from individual steps, whether load bearing or not, assembled on site with, for example, carriages or a central column.
Their shape may be straight or winding.
Stairs may incorporate parapets (on one or both sides) and landings.
Stairs may have simple bearings (e.g. on corbels, walls or beams), bolted connections or they may be connected with reinforcement and in situ concrete.
The surfaces of the precast elements may be exposed or covered by finishes.

ISO/TS 22269:2005 describes a full-scale reference scenario procedure for assessing the burning behaviour of stairs or stair coverings, when exposed to a defined ignition source. The risks addressed in this scenario are essentially those of a deliberate rather than an accidental fire. The ignition sources specified include a wood crib to represent a local attack with burning crumpled newspaper and a gas burner to represent a more severe attack when the whole width of the bottom step is attacked. The observations of burning behaviour provide a basis for assessing the fire exposure behaviour of stair coverings installed over different stair substrates. ISO/TS 22269:2005 is applicable to all types of stair coverings that can be installed on stairs or to the stairs themselves. The results obtained from this method reflect the performance of the total stair covering system together with the stair substrate as tested and are not intended to be the sole criterion for assessing the potential fire hazard of the product in use. Modifications to the stair covering, underlay, fixing system, stair substrate or other changes to the system can affect test results. Tests are performed with an enclosed or open-sided staircase. In this test method, there is no closure at the top of the stairs to represent a ceiling on a stairs landing. The top of the stairs assembly is open so that the tests are conducted under well-ventilated conditions.

This Part of EN 1366 specifies a method for determining the fire resistance of raised access floors and hollow floors when subjected to a fire from within the plenum beneath the floor. The fire exposure applied to the test specimen may be either:
a) standard time temperature curve;
b) 'reduced' time temperature curve which follows the standard time/temperature curve only up to 500 °C. After this temperature has been reached the temperature within the furnace is maintained at 500 °C.
This document does not determine the fire resistance of the sub-floor on which the raised or hollow floor is constructed; this is given in EN 1365-2.
