Where the formwork assembly is to be used under conditions of loading that are more adverse than those given in this Section. Angular tolerance for squareness shall be expressed in terms of the distance by which a shorter side of the precast unit deviates from a straight line perpendicular to the longer side and passing through the corner of the unit.
Partial collapse, damage and deformation or deformation, alone from this force is acceptable. This Standard was issued in draft form formeork comment as DR Where appropriate, eccentricity of members in tension shall also be considered.
Cast-in-situ concrete—concrete which is placed, as plastic concrete, in its final location as part of the permanent structure.

Consistently good quality of edge and joint details General external and internal facades intended to be viewed in detail Good visual quality when viewed as a whole Class 3 Class 4 Class 5 Visual quality not significant Texture not important.
Tolerances in angular dimensions Tolerances in angular dimensions cover squareness or trueness to any specified angle see Figure 3.

This Standard has limited applications for unformed concrete surfaces e.
As 3610-1995 Formwork for Concrete
The acceptance criterion is that the tested unit must be capable of withstanding a specified test load without signs of conrcete. Except for small areas as stated in Table 3. W u is for use with limit state design procedures and is derived from V u in AS For each combination, add the loads nominated in Columns 3 to 12, and multiply the sum by the factor in Column The loads shall be combined in accordance with the requirements set out for the relevant design procedure.
It consists of the form face and the framing to the form face.
This Item refers to anchors which have been installed in the concrete after it has set, e. The appropriate test results may be used as follows: Where these loads on the associated formwork can lead to instability or eccentricity of vertical loads resulting in reduced formwork strength the formwork shall be fixed to the footing system by a means adequate to resist the anticipated horizontal loads. Optical instruments, jig frames or string lines shall be used, as applicable.
That the test was in accordance with this Standard. It is therefore essential that the matters listed in Section 2 be known prior to commencement of the formwork activity and that, where applicable, they are contained in the formwork documentation.

A representative sample of timber may also be submitted to an appropriate testing authority for identification to enable visual stress grading to be achieved in accordance with the above Standards. Full details of such matters shall be given in the project documentation.
NA Not Applicable—these are matters which are not applicable to the particular class. Where strain movement of the concrete is possible, deviations shall be measured prior to removal of any forms or supports or application of prestress or post-tensioning. It shall be fitted with devices to facilitate adjustment of the formwork and to permit the controlled movement of formwork during stripping. The physical qualities of each of these classes, and their applicability, set out in Table 3.
In some unusual cases, other xs will be present, or the combinations shown will not produce fkrmwork most severe load. Where these early concrete strengths are not achieved, the times given shall be increased by a factor of 1. The light conditions at the time of evaluation and the period of time after the gor of the form before evaluation is carried out shall be consistent for all elements with similar requirements.
Trueness to an angle other than 90 degrees shall be expressed formworkk similar terms, but setting the check line in the specified angle. Larger factors may be needed in special formwork applications. BS To Be Specified—these are mandatory project documentation requirements for all work where the particular class has been specified. In the absence of site recording, local temperatures are usually available from the Australian Bureau of Meteorology.
SIA Specify If Applicable—these are mandatory where the 361 feature is included in the project documentation.
