The corresponding AEMPS SOP specifies room temperature 25 ± 5°C and relative humidity ≤60%, unless the particular formula requires otherwise. This is the work environment, not processing or storage temperature.
Follow the addition sequence, temperatures and times stated under Preparation Procedure. The specific monograph is not a complete qualification of the local facility/equipment.

Additional tests from the referenced SOP:
Appearance and mass. For batches: spreadability and microbiological testing RFE 5.1.4.
Spreadability PN/CP/003: fixed sample quantity between glass plates, with locally defined successive loads and times; measure two diameters and compare area against load. Temperature variation of ±0.5°C is suggested. The source gives no universal acceptance limit; establish it locally.
