9 Types of Activity Field INSPECTION generally refers to the following three types of activity, which occur at different periods and may require different grades of INSPECTION . Pre-commissioning INSPECTION and testing This activity should be carried out prior to the commissioning of new equipment after completion of erection or after major repairs to existing equipment. This category of INSPECTION , which is the primary concern of this STANDARD is discussed here most extensively. Maintenance INSPECTION This activity should be carried out after maintenance overhauls. This category is the routine type of INSPECTION and may be carried out using the appropriate procedures of this STANDARD .

10 On stream INSPECTION This activity should be carried out during normal operation of the equipment. This category requires mainly visual INSPECTION with strict application of test procedures especially for: - Safeguarding systems;. - Logic systems;. - Safety systems;. - Systems subject to control by customs or local authorities. On stream INSPECTION may be carried out using the relevant procedures of this STANDARD . Note 1: This is a revised version of this STANDARD , which is issued as revision (2)-2015. Revision (1)- 2005 of the said STANDARD specification is withdrawn. 2. REFERENCES. Throughout this STANDARD the following dated and undated standards/codes are referred to.
