This document specifies a method of test for determining the ignitability of products by direct small flame impingement under zero impressed irradiance using vertically oriented test specimens. Information on the precision of the test method is given in Annex A (informative). Information on testing not essentially flat end-use products is given in Annex B (normative). Information on testing perforated end-use products is given in Annex C (normative).

 

This standard aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from releases of flammable gas, pressurised liquefied gas, flashing liquid fuels or dust that may precede a fire. Explosions can give rise to pressure and drag forces. Damage to PFP materials and systems in an explosion can be caused by the direct effects of pressure and drag loadings and by the distortion of the substrate supporting the PFP material. This standard considers PFP materials applied to panels, plates etc that could be used as divisional elements. The loading on this type of element predominantly results from the explosion pressure applied and drag loadings are typically minimal. Test laboratories should be aware of the significant potential hazards involved in gas explosion resistance testing and take appropriate steps to ensure the safety of all concerned.

 

This standard specifies a method for the quantitative analysis of residual quartz (i.e. alpha-quartz) in silica bricks within the concentration range from 0,3 % to 5,0 % wt, by X-ray diffraction (XRD) using a Bragg-Brentano diffractometer. It includes details of sample preparation and of preliminary establishment of a working curve using external standards.

 

This document specifies a testing method for determining the elastic modulus of glazed and unglazed ceramic tiles and also the modulus of glaze layer at ambient temperature by three-point bending tests. Procedures for test piece preparation, test modes and load rates, data collection and reporting are given. This test method can be used for material research, quality control, characterization and design data-generation purposes of ceramic tiles with a plate shape.

 

This norm describes a method for determining the tensile adhesion strength of multilayer ceramic tiles and specifically the adhesion between the back of the multilayer and the cementitious adhesive used for installation.

 

This document, used in conjunction with ISO 834-1, specifies a method for determining the fire resistance of door and shutter assemblies designed primarily for installation within openings incorporated in vertical separating elements, such as Requirements are included for mechanical pre-conditioning, e.g. “cycling” of door and shutter assemblies prior to the conduct of the fire-resistance test.

 

(1) This document specifies additional requirements to prEN 206 1 for the constituents, specification and conformity control of concrete used in: - bored piles constructed in accordance with EN 1536; - diaphragm walls constructed in accordance with EN 1538; - cast-in-place displacement piles constructed in accordance with EN 12699; - micropiles constructed in accordance with EN 14199. (2) The requirements provided in this document are specified in accordance with prEN 206 1:2024, 7.2 Specifications for designed concrete. (3) This document can also apply to applications in special geotechnical works other than those listed above. NOTE 1 For special geotechnical works provisions on cement, minimum cement content, minimum fines content, maximum water/binder ratio, target values of fresh concrete properties and maximum tolerances for target values can deviate from the provisions for other works in prEN 206 1. (4) This document is based on the assumption that the specification is based on considerations including the site conditions and the conditions for execution of concrete used in special geotechnical works. NOTE 2 Guidance for the specification of concrete used in special geotechnical works can be found in the informative Annex A.

 

(1) This document applies to concrete for structures cast in situ, precast structures, and structural precast products for buildings and civil engineering structures. (2) The concrete under this document can be: - normal-weight, heavy-weight and lightweight; - mixed on site, ready-mixed or produced in a plant for precast concrete products; - compacted or self-compacting to retain no appreciable amount of entrapped air other than entrained air. (3) This document specifies requirements for: - the constituents of concrete; - the properties of fresh and hardened concrete; - the limitations for concrete composition; - the specification of concrete; - the delivery of fresh concrete, - the production control procedures; - the assessment criteria for individual values. (4) This document does not apply to: - aerated concrete; - foamed concrete; - concrete with density less than 800 kg/m3; - refractory concrete. (5) This document does not cover health and safety requirements for the protection of workers during production and delivery of concrete.

 

(1) This document specifies the scheme for the conformity assessment and assessment criteria for concrete. (2) The document provides technical rules for testing of samples and assessment of the performance of the concrete. It also provides rules for actions to be followed in the event of non-conformity of the product or negative assessment. (3) In this document, the word “concrete” is used to refer concrete as defined in prEN 206 1. Such a concrete is produced at a given plant and belongs to a particular type and a particular strength class, as defined and specified in prEN 206 1.
