This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid
product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the
temperature(s) specified e.g. in regulations.
NOTE Many national and international regulations classify liquids as presenting a flammable hazard based
on their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the
substance cannot “sustain combustion” at some specified temperature(s).
The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents,
petroleum or related products and adhesives, that have a flash point. It is not applicable to painted
surfaces in respect of assessing their potential fire hazards.
This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard
of a product.

This European Standard specifies analysis and evaluation procedures for determining self-ignition temperatures (TSI) of combustible dusts or granular materials as a function of volume by hot storage experiments in ovens of constant temperature. The specified test method is applicable to any solid material for which the linear correlation of lg (V/A) versus the reciprocal self-ignition temperature 1/TSI (with TSI in K) holds (i.e. not limited to only oxidatively unstable materials).
This European Standard is not applicable to the ignition of dust layers or bulk solids under aerated conditions (e.g. as in fluid bed dryer).
This European Standard shall not be applied to dusts like recognised explosives that do not require atmospheric oxygen for combustion, nor to pyrophoric materials.
NOTE   Because of regulatory and safety reasons "recognised explosives" are not in the scope of this European Standard. In spite of that, substances which undergo thermal decomposition reactions and which are not "recognised explosives" but behave very similarly to self-ignition processes when they decompose are in the scope. If there are any doubts as to whether the dust is an explosive or not, experts should be consulted.

This document describes and classifies a range of laboratory ignition sources for use in fire tests on plastics and products consisting substantially of plastics. These sources vary in intensity and area of impingement. They are suitable for use to simulate the initial thermal abuse to which plastics are potentially exposed in certain actual fire risk scenarios. This compilation of standard ignition sources describes the ignition sources used by different standards development organizations and contained in standard test methods, specifications, or regulations used to assess the fire properties or plastics and of products containing plastic materials. The ignition sources described in this document are associated with flaming and non-flaming ignition. This document describes the relevant ignition sources and references the associated standard. This compilation of ignition sources does not discuss the application of the standard referenced in any specific clause in which the ignition source is described, and this compilation is likely not to be a fully comprehensive list of ignition sources. This document does not address detailed test procedures.

This document specifies requirements for, and constructions and dimensions of, multicore and multipair cables rated voltage U0/U: 300/500 V, of the following types: - unscreened, sheathed for either exposed or protected wiring (0,5 mm2 to 2,5 mm2, number of cores from 2 to 48); - screened, sheathed for either exposed or protected wiring (0,5 mm2 to 2,5 mm2, number of cores from 2 to 8); - unscreened, sheathed for either exposed or protected wiring (0,5 mm2 to 1,5 mm2, number of screened pairs of cores from 2 to 7). - screened, sheathed for either exposed or protected wiring (0,5 mm2 to 1,5 mm2, number of unscreened pairs of cores from 2 to 7). All cables have stranded tinned copper conductors, halogen-free, thin wall thickness insulation and standard wall thickness sheath. Cable types are specified for use in exposed situations (Class E), and for protected situations (Class P). They are for use in railway rolling stock as fixed wiring or wiring where limited flexing in operation is encountered. These cables are rated for occasional thermal stresses causing ageing equivalent to continuous operational life at a temperature of 90 °C. For standard cables this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 110 °C/20 000 h temperature index. If the customer were to require lifetime predictions this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. Under fire conditions the cables exhibit special performance characteristics in respect of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. These requirements are specified to permit the cables to satisfy Hazard Level 3 of EN 45545 1 and EN 45545 2. EN 50306 4:2020 is expected to be used in conjunction with EN 50306-1:2020, General requirements, EN 50306-2:2020, Single core cables, and EN 50306-3:2020, Single core and multicore cables.

This document establishes the general principles for determining the fire resistance of various elements of construction when subjected to standard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 1363-2.
The principle that has been embodied within all European standards relating to fire resistance testing is that where aspects and procedures of testing are common to all specific test methods e.g. the temperature/time curve, then they are specified in this test method. Where a general principle is common to many specific test methods but the details vary according to the element being tested (e.g. the measurement of unexposed face temperature), then the principle is given in this document, but the details are given in the specific test method. Where certain aspects of testing are unique to a particular specific test method (e.g. the air leakage test for fire dampers), then no details are included in this document.
The test results obtained might be directly applicable to other similar elements, or variations of the element tested. The extent to which this application is permitted depends upon the field of direct application of the test result. This is restricted by the provision of rules which limit the variation from the tested specimen without further evaluation. The rules for determining the permitted variations are given in each specific test method.
Variations outside those permitted by direct application are covered under extended application of test results. This results from an in-depth review of the design and performance of a particular product in test(s) by a recognized authority. Further consideration on direct and extended application is given in Annex A.
The duration for which the tested element, as modified by its direct or extended field of application, satisfies specific criteria will permit subsequent classification.
All values given in this document are nominal unless otherwise specified.

This part of this European Standard specifies requirements for fire resisting data cabinets and diskette inserts.
Two methods of test are specified to determine the ability of fire resisting data cabinets to protect temperature and humidity sensitive contents from the effects of fire: a fire endurance test and a fire shock and impact test. Two levels of fire severity (S 60 and S 120) based upon time of fire exposure; and three protection classes (P, D and DIS) are specified using the maximum temperature increases and humidity values permitted within the storage space of the data cabinet.
Diskette inserts (DI 60 P/DIS and DI 120 P/DIS) are installed in data cabinets of protection class S 60 P or S 120 P, respectively, and subjected to a fire endurance test (see 5.1.2).
Requirements are also specified for test specimens, the technical documentation for the test specimen, correlation of the test specimen with the technical documentation, preparation for type testing and test procedures.
A scheme to classify the fire resisting data cabinets and diskette inserts from the test results is also given (see Table 1).
Diskette inserts should only be installed in data cabinets having the same design as the series of protection class S 60 P and S 120 P, respectively, in which the insert has been tested in accordance with 5.1.2. Where several inserts are installed, they should be built in one beside the other or one above the other from bottom to top, respectively. The volume and total height of the installed inserts should not exceed 50 % of the total internal volume or 50 % of the internal height, respectively, of the data cabinets into which they are installed. The dimensions of the insert can be adapted by increasing the width and depth to the corresponding dimensions of the data cabinets. A reduction of these dimensions as well as a change of the height is only admitted within the specified tolerance.
The temperature increases during type-tests on data cabinets and diskette inserts will be considered in deciding the permitted diskette insert installations. For a permitted installation, the temperature increase of the intended data cabinet (∆T_A∙K) should not exceed the temperature increase of the tested data cabinet (∆T_B∙K) in which the diskette insert has been type-tested by more than the difference between the maximum value for the diskette insert (∆T_i∙K) and the maximum admissible temperature increase (30 K), i.e ∆T_A- ∆T_B≤30 K- ∆T_i (See example in Annex B).
A description of the installation of the diskette inserts should be given in the technical documentation of the manufacturer.

This document specifies the test for the determination of the resistance of non-metallic materials in part or in whole to flame and glow propagation and to flame penetration. This test method is also used for testing non-metallic materials which have to meet the test criteria for the 45° Bunsen burner test. It is used for evaluation of non-metallic materials or constructions used in the interiors of aerospace vehicles but also may be used in other applications as specified in applicable procurement and regulatory documents. This standard should be used to measure and describe the properties of non-metallic materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard. An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments. NOTE 1 The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user’s risk analysis. NOTE 2 This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.  NOTE 3 This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document. Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of the Incident energy limit (ELIM) as a further arc rating performance property value; - replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2; - clarification of the definition and the meaning of the Stoll curve; - modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens; - modification of specifications of monitor sensor construction; - specification of black paint; - elimination of calorimeters from the chest of the mannequin; - specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance; - more explicit description of requirements for data acquisition system; - preconditioning of the samples; - modification of requirements for apparatus and arc exposure verification by bare shots; - more explicit description of test procedures A and B, in particular the subclauses dealing with “sequence of test”, “test parameter” and “test criteria”; - addition of determination of arc rating values of garments and/or garmet assemblies. Key words: Protective Clothing, Thermal Hazards, Open Arc, Arc Rating
