FOREWORD This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, atler the dratl finalized by the Security Equipment Sectional Committee hadbeen approved by the Mechanical Engineering Division Council. This standard was first pubIished in 1996. The experience gained in implementation of the standard necessitated this revision. In this revision the ventilators are classified into four classes in place of earlier-three classes. Theconstruction ofair ventilators forthe strong rooms andvaults, which are primarily meant toprovide ventilation facility inside avault (strong room), shall be such aswill prevent direct access to the inside of vaults from outside and vice versa. This indirect access ismeant to ensure preventing the spread of tire from gutside of vaults to inside and thereby to prevent damage to the contents of vaults due to fire. The composition of the Committee responsible for the formulation of this Indian Standard is given in Annex A. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed and 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. 1S14387:2005 Indian Standard VAULTS — AIR VENTILATORS — SPECIFICATION (First Revision ) 1 SCOPE IS No. Title This standard lays down the requirements regarding 2062:1999 Steelforgeneralstructuralpurposes materials;sizesanddetailsofconstructionofairventilators — Specification (f2jlhrevision) (which are used for ventilating vaults) so as to ensure 2932:1993 Enamel, -synthetic, exterior : (a) that security is not adversely affected. undercoating (b) finishing (second revision) 2 REFERENCES 5986:2002 Hot rolled steel flat products for structural forming and flanging The following standards contain provisions, which purposes —Specification (second through reference in this text, constitute provision of revision) this standard.
