Steam Trap Inspection and Test Plan Points

H: Hold Point implies that relevant production activities shall not proceed until the continuation of work is permitted by Purchaser. (Notification req'd)

W: Witness point implies that Purchaser intends to witness the designated inspection feature. If Purchaser decides not to witness the relevant feature, production can proceed without permission of Purchaser. (Notification req'd)

S: Witness, but spot check basis. Initial operation will be witness point and subsequent operation will be witnessed at discretion of Purchaser considering the results of previous inspection. (Random Inspection : Notification not req'd)

R: Review inspection & test records (Notification not req'd)

You need to add three more columns in above ITP, one for related construction code, the second one for acceptance criteria and third one for verifying documents.

Your acceptance criteria must meet your construction code. The verifying document must be fill out for each item in above ITP. These documents are inspection reports, test records, material certificates, test procedures, etc.
