4 BUREAU OF INDIAN STANDARDS DRAFT (Not to be reproduced without the permission of BIS or used as an Indian Standard) Draft Indian Standard Smoke and Heat Control Systems Part 1 : Specification for Smoke Barriers (Adoption of ISO :2008) ICS Not to be reproduced or used as Last Date for Comments STANDARD without permission of BIS 28 February 2019 Fire Safety Sectional Committee, CED 36 NATIONAL FOREWORD (Adoption clause would be added later) This Indian Standard (Part 1) is identical with ISO :2008 Smoke and Heat Control Systems Part 1: Specification for Smoke Barriers issued by the International Organization for Standardization (ISO). However, ISO has published the following other parts in its ISO series namely: Part 2 : 2018 Part 3 : 2006 Part 5 : 2018 Part 7 : 2017 Part 8 : 2017 Part 9 : 2012 Part 10 : 2011 Specifications for natural smoke and heat exhaust ventilators Specification for powered smoke and heat exhaust ventilators Powered smoke exhaust systems -- Requirements and design Smoke ducts sections Smoke control dampers Specification for control equipment Specification for power output devices Part 4 on Natural smoke and heat exhaust ventilators -- Design, requirements and installation is under development at ISO. The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words International Standard appear referring to this standard, theyshould be read as Indian Standard. b) Comma (,) has been used as a decimal marker while in Indian Standards, the currentpractice is to use a point (.) as the decimal marker. In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards which are to be substituted in their places, are listed below along with their degree of equivalence for the editions indicated: 1

Details of which are given in Annex G (National Annex). For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. 2

6 INTRODUCTION General Smoke and heat exhaust ventilation systems (SHEVS) create a smoke-free layer above the floor by removing smoke and heat and thus improve the conditions for the safe escape and/or rescue of people and animals and the protection of property and permit the fire to be fought while still in its early stages. The use of smoke and heat exhaust ventilation systems to create smoke-free areas beneath a buoyant smoke layer has become widespread. Their value in assisting in the evacuation of people from construction works, reducing fire damage and financial loss by preventing smoke logging, facilitating fire fighting, reducing roof temperatures and retarding the lateral spread of fire is firmly established. To obtain these benefits, it is essential that SHEVS operate fully and reliably whenever called upon to do so during their installed life. A SHEVS is a scheme of safety equipment intended to perform a positive role in a fire emergency. It is important that the components for smoke and heat exhaust systems be installed as part of a properly designed smoke and heat exhaust system. SHEVS help to keep the escape and access routes free from smoke, facilitate fire fighting operations by creating a smoke-free layer, delay and/or prevent flashover and thus full development of the fire, protect equipment and furnishings and contents, reduce thermal effects on structural components during a fire, reduce damage caused by thermal decomposition products and hot gases. For the purpose of this part of ISO 21927, a smoke barrier is deemed to be any form of barrier to the movement of fire effluent. Smoke barriers control the movement of fire effluent within a construction works in the event of fire. Smoke barriers, when used within a smoke heat control system, become a critical element of that system. If smoke barriers are not in their fire-operational position, the system does not perform as designed. However, even in the event that other elements of the SHEVS (Smoke and Heat Exhaust Ventilation Systems) do not function, smoke barriers in the fire operational position provide essential smoke containment and channelling. This Part of ISO applies to smoke barriers used within smoke and heat control systems, which include other equipment, e.g. natural smoke and heat exhaust ventilators (ISO ) and powered smoke and heat exhaust ventilators (ISO ). Smoke barriers perform within specific time/temperature ranges. Function of smoke barriers The function of smoke barriers is to control the movement of fire effluent within construction works by forming a barrier. The functions of active or manually deployed 3

7 smoke barriers are identical to those of static smoke barriers, but they also can be retracted and concealed when not in use. Typical functions of smoke barriers are to create a smoke reservoir by containing and limiting the travel of the smoke; channel smoke in a pre-determined direction; prevent or retard smoke entry to another area or void. Applications of smoke barriers The primary applications of smoke barriers are listed below. However, as their application becomes more widespread, it is inevitable they will be put to a wider variety of uses. It is important to note that, within the scope of this part of ISO 21927, smoke barriers can contain smoke and gases in excess of 600 C but are not intended to perform the same function as fire doors and shutters tested in accordance with ISO 3008 or smoke-control doors tested in accordance with ISO Typical applications for smoke barriers are as smoke reservoir boundaries, channelling screens, void edge screens, void sealing screens, corridor containment, shop unit containment, escalator containment, stairwell containment, elevator well containment. Types of smoke barrier Construction-works elements can be used to create static smoke barriers and they can be augmented by smoke barriers covered by this standard. This standard applies to the following types of smoke barriers: static smoke barriers (SSB), active smoke barriers (ASB). A wide range of different materials can be used to create smoke barriers. Typical materials used for static smoke barriers include fabric, glass, metal, fire-resisting board, fibreglass and mineral wool or any impermeable material capable of resisting smoke at temperatures required by the design. Typical examples of active smoke barriers include roller, pleated, folding, hinged or sliding, using the types of material as described for static smoke barriers. Static and active smoke barriers are categorized by type and performance in Clause 5. In addition, an ASB product is deemed to include all controlling equipment, etc. This does not include external controls, for example a fire alarm or a sprinkler flow switch. 4
