SAUDI ARAMCO STANDARD FOR PIPING QC..

QA-QUALITY ASSURANCE- Is the planning and organizing of system program to maintain a required level of quantity or reliability. This includes auditing the systems in operation and related controls to assure that they are being executed properly and functioning as expected.

QC - QUALITY CONTROL- Is a part of quality assurance   implements the letters by examining the physical characteristics and comparing them to established and acceptable quality and documents as stated in quality assurance program or plan.

ITP   - Inspection Test Plan mean the document sequences for quality activities in process,highlights the applicable quality and inspection criticality.

S -Surveillance:  QA/QC organization to monitor work in progress without notice of construction      organization.

W-Witness point:    QA/QC organization shall be notified   with the timing inspection in advance, however the inspection or test shall be performed as schedule if the QA/QC representative is not present.

H- Hold point:  QA/QC organization shall be notified of the timing of inspection on test in advance, inspectiontest shall not be carried out ,without the QA/QC organization representative in advance.

NCR- in case of violation of quality document by the contractor  NCR will be issued. The fulfillment or the required  corrective action will be mandatory by the contractor.

R- Review:  

* Documents review    =   Review

* Material receiving     =   Witness/Surveillance
