Here you can have the minimum audit time calculated for IFS Food
*1 audit day corresponds to 8 hours. The minimum audit duration is two (2) days. A reduction up to 0,75 days can apply in some specific conditions as described in the Doctrine 220.127.116.11. If the calculation tool provides an audit duration which is longer than 2 days and if the company organization justifies it, the certification body can reduce duration, but never under the full day provided by the tool. For example, an audit duration of 3,5 days can be reduced to 3 days. In the audit report, the certification body shall specify the reason of this reduction (doctrine 18.104.22.168).
