These shall be at least at the ends and point of maximum deflection. NOTE: Typically this should be the mid-span of structural members and swinging door stiles. The location of the probes should be as close to the ends of the structural member as possible. The framework to support the displacement measuring devices shall be rigidly fixed, independent of the test sample. Before tests are commenced, the location of all displacement measuring devices shall be agreed between the client and the test laboratory Test procedure The test procedure and loading sequence shall be as follows: (a) (b) (c) (d) An initial pressure equivalent to 50% of the test pressure shall be applied to the test sample and held for 1 min. This shall be taken as a settling-in take-up period. The pre-load pressure shall be removed and the zero position of the displacement measuring devices recorded. Differential pressures in the same direction shall then be applied across the test sample in not less than four approximately equal increments until the test pressure is reached. The pressure shall be held for at least 1 min at each pressure increment, and the readings of the displacement measuring devices recorded before the pressure is increased. The differential pressure shall be removed and after 2 min the zero displacement readings shall be taken. (e) The direction of the pressure device, or test sample shall be reversed and Steps (a) to (d) shall be repeated using the opposite test loading. 3.4 Calculation of displacement/span ratio Where a structural member of the test sample is effectively supported at its ends only, its mid-span displacement and resultant displacement/span ratio under load shall be calculated as follows: (a) The mid-span deflection (d) of each member is given by the following equation: d = D m D e... 3(1) where D m = maximum displacement of member (generally at mid-span) D e = average of net end displacements (b) The resultant deflection/span ratio is given by the following equation:

For horizontally sliding sashes, the force shall be applied either at the position of a fixed handle, or at one-third of the height of the pull stile above the sill for continuous or adjustable handgrips. For vertically sliding sashes, the force shall be applied at the sash pulls or at the midpoint of the bottom rail.

Intermediate assembly End assembly Intermediate assembly (a) Even panel system (b) Odd panel system FIGURE 4.1 DEFINITION OF INTERMEDIATE AND END ASSEMBLIES Where the sample is wide enough that it contains more than one type of roller/guide assembly then each assembly shall be tested separately and the worst case figures shall be used, e.g. a six-panel folding assembly contains two intermediate assemblies and one end assembly so both the intermediate assemblies would be tested and the worst case figure used. The force measuring device shall be attached to a hinge handle. If no handle is present, the force measuring device shall be attached to the panel at approximately the midpoint of the panel as shown in Figure 4.2. End assembly Intermediate assembly Force gauge mounting position FIGURE 4.2 DEVICE ATTACHMENT POINT FOR HANDLE-LESS SYSTEM

The test shall continue until the carrier assembly panel almost contacts the adjacent panel for opening and until the panels are almost closed for closing. Each carrier assembly shall be tested three times for both opening and closing and the force required to initiate movement and maintain movement shall be measured and recorded. The average value of the three measurements shall be used as the maximum forces for initiate and maintain, for both opening and closing. 4.4 Test report In addition to the information required by Clause 2, the following information shall be reported: (a) Reference to this Standard, i.e. AS/NZS Clause 4 Operating force test.

17 PREPARATION OF JOINT AUSTRALIAN/NEW ZEALAND STANDARDS Joint Australian/New Zealand Standards are prepared by a consensus process involving representatives nominated by organizations in both countries drawn from all major interests associated with the subject. Australian/New Zealand Standards may be derived from existing industry Standards, from established international Standards and practices or may be developed within a Standards Australia, Standards New Zealand or joint technical committee. During the development process, Australian/New Zealand Standards are made available in draft form at all sales offices and through affiliated overseas bodies in order that all interests concerned with the application of a proposed Standard are given the opportunity to submit views on the requirements to be included. The following interests are represented on the committee responsible for this draft Australian/ New Zealand Standard: Australasian Institute of Surface Finishing Australian Building Codes Board Australian Glass and Glazing Association Australian Industry Group Australian Window Association Building Research Association of New Zealand CSIRO Glass Association of New Zealand Housing Industry Association Master Builders Australia Master Locksmiths Association of Australasia National Association of Testing Authorities Australia New Zealand Joinery Manufacturers Federation Window and Door Industry Council Window Association of New Zealand

18 Standards Australia Standards Australia is an independent company, limited by guarantee, which prepares and publishes most of the voluntary technical and commercial standards used in Australia. These standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth government, Standards Australia is recognized as Australia s peak national standards body. Standards New Zealand The first national Standards organization was created in New Zealand in The New Zealand Standards Executive is established under the Standards and Accreditation Act 2015 and is the national body responsible for the production of Standards. Australian/New Zealand Standards Under a Memorandum of Understanding between Standards Australia and Standards New Zealand, Australian/New Zealand Standards are prepared by committees of experts from industry, governments, consumers and other sectors. The requirements or recommendations contained in published Standards are a consensus of the views of representative interests and also take account of comments received from other sources. They reflect the latest scientific and industry experience. Australian/New Zealand Standards are kept under continuous review after publication and are updated regularly to take account of changing technology. International Involvement Standards Australia and Standards New Zealand are responsible for ensuring that the Australian and New Zealand viewpoints are considered in the formulation of international Standards and that the latest international experience is incorporated in national and Joint Standards. This role is vital in assisting local industry to compete in international markets. Both organizations are the national members of ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission). Visit our web sites
