The standard specifies the maximum allowable deflection \(\triangle_{max}\)for flexural members to be \(\frac{L}{270}\) where \(L\) is the center to center span of the flexural member. For example, a joist spanning \(L=1.2m\) is allowed to deflect \(\triangle_{max}=4.4mm\). Clause 6.3.5
For long span, although it isn’t formally required by the standard, formwork equipment manufacturers or designers often chose to limit the flexural member deflection to \(\triangle_{max}=6mm\) or \(\frac{1}4in\).
It is at the engineer discretion to remove the live load form the deflection calculation since this load is applied temporary during the placement of the fresh concrete and that the live load is must likely not present while the concrete is curing.
