Filter Inspection and Test Plan

This content provides you with a example filter inspection and test plan. This is a draft filter ITP and must be modified based on your PO requirements. You may also read the pressure vessel ITP article for more information. There is a draft ITP there, you can download the ITP and use alongside of this ITP to support you to generate your own ITP based on your specifications.

Filter 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)

General Note for Filter ITP:

1) Filter Witness/hold point by Code Inspector, when applied by Code Stamp/Local Regulation, is to comply with its requirements and to specify in Vendor's ITP.

2) Type of Inspection by Filter Purchaser may be changed according to equipment criticality and vendor QC evaluation at job stage.

3) When requested in the requisition, detailed Filter ITP shall be submitted by Vendor.

4) Monitoring/Observation of Filter Vendor shop daily routine works (i.e. Storage of materials & welding consumables, Adherence to approved procedures, Testing tool calibration check, Welder/NDE Operator performance & qualification, workmanship, cleanliness and etc.) shall be done by Purchaser during inspection visit.

5) Filter Final Visual Inspection/Documentation Review/Pre-Shipment Inspection may be combined within one time visit.
