EN 16733:2016 (E) 3 European foreword This document (EN 16733:2016) has been prepared by Technical Committee CEN/TC 127 “Fire safety in buildings”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2016, and conflicting national standards shall be withdrawn at the latest by February 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This standard is produced in response to the EC mandate M/385. CEN/TC 127 was requested to develop this test method to determine possible glowing combustion behaviour in building products. This test method forms part of the present EC classification system for the reaction to fire. Task Group 6 of CEN TC 127/WG4 was created to develop this test method. In the early stages of its development, it was found that the term ‘glowing combustion’ as defined in EN ISO 13943 does not completely characterize the specific combustion behaviour of a building product. In particular, the increase of temperature which is considered as typical for the process of smouldering is not considered in the EN ISO 13943 definition. Therefore the task group made a clarification and changed the term glowing combustion to smouldering combustion. Smouldering is defined in this standard as 'combustion of a material without flame and with or without visible light’. This includes glowing combustion. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16733:2016 (E) 4 Introduction This test method has been developed considering methods NT FIRE 002 and NT FIRE 035 and standards BS 5803-4 and Önorm B 3800. It specifies a test for determining the propensity of products to smoulder continuously when tested in a vertical orientation. The method does not impose a mechanically influenced airflow through the test specimens since this would not represent most end-use conditions. Safety warning The attention of all persons concerned with managing and carrying out this test is drawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful smoke and gases may be evolved during the test. Operational hazards may also arise during the testing of specimens and the disposal of test residues. An assessment of all potential hazards and risks to health should be made and safety precautions should be identified and provided. Written safety instructions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written safety instructions at all times. Adequate means of extinguishing the specimen should be provided, bearing in mind that some specimens may produce severe flaming during the test. A hand water spray or an inert gas suppression system e.g. compressed nitrogen which can be directed to the burning area should be available together with other means, such as fire extinguishers etc. In some cases, smouldering may be difficult to extinguish completely and immersion in water may be necessary.

EN 16733:2016 (E) 5 1 Scope This European Standard specifies a test method to determine the propensity (ability) of a building product to smoulder continuously when exposed to an open flame under the influence of natural convective airflow. It is intended for all building products classified according to EN 13501-1. Details as to how the products is mounted and fixed for this test are given in the relevant product standards. The field of application of the test results is defined in the product standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 16733:2016 (E) 6 3.7 smouldering combustion of a material without flame and with or without visible light. This includes glowing combustion Note 1 to entry: Smouldering is generally evidenced by an increase in temperature and/or by the presence of effluents. 3.8 progressive smouldering self-propagating exothermic oxidation that is not accompanied by flaming combustion Note 1 to entry: It can be accompanied by glowing. 3.9 sustained flaming persistence of flaming for a period greater than 10 s 3.10 flame spread propagation of flame away from the source of sustained flaming 3.11 glowing combustion combustion of a material in the solid phase without flame but with emission of light from the combustion zone 4 Principle One test specimen is vertically mounted and exposed to constant heat from a propane gas burner with its flame impinging on the specimen surface. Smouldering is detected by measuring temperatures by using thermocouples installed at defined distances within the vertical test specimen and the observation of sustained flaming following re-ignition. 5 Test apparatus 5.1 Main apparatus NOTE All dimensions given in the following description are nominal unless tolerances are specified. The main apparatus is shown in Figures 1, 2 and 3. The apparatus includes: — specimen holder; — propane burner; — wire mesh box (Figure 4); — six thermocouples inside the specimen connected to a recording device (Figure 5); — specimen holder frame to hold flexible or thin products in place (Figure 6).
