Indian StandardSPECIFICATION FOR

ALUMINIUM WINDOWS FORINDUSTRIAL BUILDINGS

o. FOREWORD

0.1 This Indian Standard was adopted by theIndian Standards Institution on 2 November1961, after the draft finalized by the Doors,Windows and Building Furniture SectionalCommittee had been approved by the BuildingDivision Council.0.2 This specification is an adjunct to IS: 1361­1959 Specification for Steel Windows for Indus­trial Buildings which covers steel windows forindustrial buildings. With the increasing useof extruded aluminium alloys sections in themanufacture of windows, it was felt that aseparate standard be prepared on the linesof IS: 1361-1959 to cover the requirementsof aluminium industrial windows and theirfittings.0.3 The .izes of aluminium industrial windowsand other requirements and details are identi­cal to those of the steel windows covered byIS: 1361-1959 Specification for Steel Windows forIndustrial Buildings, unless otherwise specified.

o.t The Sectional Committee responsible for thepreparation of this standard has taken into consi­deration the views of producers, consumers andtechnologists and has related the standard tothe man ufacturing and trade practices follow­ed in the country in this field. Due weight­age has also been given to the need for inter­national co-ordination among standards prevailingin.different countries of the world in this field.

0.5 This standard is one of a series of IndianStandards on metal doors and windows. Other

1. SCOPE

1.1 This standard deals with aluminium windowssuitable for use in industrial buildings and design­ed to suit openings based on a module of 10 em.

2. TERMINOLOGY

2.0 For the purpose of this standard, the follow­ing definitions shall apply.

2.1 S.sh - A complete window unit whetherfixed or the opening type.

0.6 Wherever a reference to any Indian Standardappears in this specification, it shall be taken asa reference to the latest version of the standard.0.7 Metric system has been adopted in Indiaand all quantities and dimensions in this stan­dard have been given in this system.0.8 For the purpose of deciding whether a parti­cular requirement of this standard is compliedwith, the final value, observed or calculated,expressing the result of a test, shall be roundedoff in accordance with IS: 2-1960 Rules forRounding Off Numerical Values (Revised). Thenumber of significant places retained in therounded off value should be the same as that ofthe specified value in this standard.0.9 This standard is intended chiefly to coverthe technical provisions relating to aluminiumindustrial windows, and it does not include allthe necessary provisions of a contract.

·Second revision in 1975.

2.2 Composite Wbadow - A window compria­ing two or more sashes joined together with oneor more coupling members.

2.3 Vea.tilator - The opening part of a lash.It consistsof an inner frame and outer frame.

2.4 Centre-HaDI VeatBator - A ventilatorhorizontally pivoted at the centre on each side,with the top half opening inwards and bottomhalf opening outwards.

2.5 Bottom-HaDI Veadlato.. - A ventilatorhinged at the bottom, and opening inwards.

2.6 Top-HuDI VeDdlator - A ventilator hingedat the top, and opening outwards.

3. DESIGNATION3.1 In designating the different sizes and typesof industrial windows, the following notation shallbe adopted:

IN X Width of window expressed in numberof modules X Type of window X Height ofwindow expressed in number of modules

The letters IN indicate an industrial window;and the type ofwindow is indicated by the follow­Ing letter symbols:

F = Fixed sash,C = Centre-hung sash,B = Bottom-hung sash, andT = Top-hung sash.Examples:

I) IN 10 C 15 indicates C Industrial windowfor opening 10 module wide ( 100 cm) by15 module high ( 150 em)' with centre­hung ventilator.

2) IN 16 F 10 indicates 'Industrial windowfor opening 16 module wide ( 160 em)by 10 module high ( 100 cm)' with fixedglass panes.

3.2 Composite Windows - For composite win­dows, the notations illustrated below shall beadopted:

a) IN 10 C 10/IN 10 C 10/IN 10 C 10: Thisindicates three industrial windows of typeIN 10 C 10, placed next to one another andcoupled.IN 10 C 10/IN 10 C 10 ...

b) IN 10 CIS/IN 10 C 15: ThiS Indicates thecombination of four windows, two of thetype IN 10 C lOon top and two of thetype IN 10 C 15 at the bottom, all the fourof them coupled both horizontally andvertically.

4. SIZES AND TOLERANCES4.1 The sizes of industrial sashes shall be asgiven in Fig. 1 (SII P 4).

NOTE - The overall width and height of the windoware smaller than the dimensiollJ of modular opening by2·5 em, thus providing a clearance of 1·25 em all roundwhen fitted into the opening.

4.2 The ventilators shall be of one size and de­signed to fit into the outer frame of IN 10 C 10and with 1·2 mm clearance.4.3 The overall dimensions of industrial windowsshall not differ from those given in Fig. 1 by morethan 3 mm.

Allbolts, nuts, screws, washers and other mild steelfittings shan be suitably corrosion treated.5.6 Screw threads of machine screws used in themanufacture of aluminium windows for indus­trial buildings shall conform to the requirementsof ~IS: 1362-1959 Dimensions for Screw Threadsfor General Purposes (Diameter Range 0·25 to39 mm ). Other threads shall be permissible ifagreed to between the purchaser and the vendor.

6.. CONSTRUCTION

6.1 Sashes shall be square and flat.6.2 Sashes shall be constructed of sections whichhave been cut to the required length and tenonedand riveted or welded at the corners. Tee sec­tions for glazing shall be tenoned and rivetedinto the frames and where they intersect, thevertical tee shall be broached and the horizontaltee threaded through it, and the intersectionclosed by hydraulic pressure. Brazing for cor­ner joints may also be done.6.3 Ventilators, consisting of an inner openingframe and an outer fixed frame, shall be madeas separate units which shall be bedded in masticand screwed into the sash frames or tees withaluminium or galvanized or cadmium-plated steelscrews. The bars forming the vertical membersof the inner and outer frames of centre-hungventilators shall be reversed at the point ofrivot;the top ban of inner and outer frames 0 top­hung ventilators, and the bottom bars of innerand outer frames of bottom-hung ventilatorsshall also be reversed ( Sll Fig. 4, P 7 ).
