1 ACCREDITATION OF MANUFACTURERS AND INSTALLERS OF PRESSURE PIPING PARTS AND SYSTEMS TSSA GUIDE FOR SURVEY TEAMS The Technical Standards and Safety Authority Boilers and Pressure Vessels Safety Division 345 Carlingview Drive Toronto, ON M9W 6N9 CANADA August 2016 Rev. 3

2 INTRODUCTION This guide is prepared for the use of TSSA non-nuclear survey team leaders, members and applicants for TSSA Certificates of Authorization. It is not intended to replace or interpret the requirements of the CSA B-51 Standard or the ASME Boiler and Pressure Vessels Codes, B31.1, B31.3 and B31.5. The checklist does not list all of the detailed requirements of the CSA B-51 and ASME Codes referenced, but rather lists the highlights that the applicant is required to include in the written Quality Control (QC) Manual. In addition, to assist the TSSA survey team, this guide is provided to applicants for TSSA Certificates of Authorization for their use in identifying and verifying the paragraph(s) where their QC Manual addresses all applicable control requirements of the CSA Standard and ASME Codes. The QC Manual must contain the description of the controls necessary for implementing the QC Program but, it is not required to contain all of the programmatic requirements which will be found in the QC Program, such as written procedures. The guide is based upon CSA B-51 and ASME B31.1, B31.3 and B31.5 requirements. The guide is subject to revision by TSSA based on changes made to CSA B-51 and ASME Codes, from time to time, or based on feedback received from users. A survey must cover a QC Manual and its implementation. It is recognized that the scope of work, QC Manual and Manual implementation will vary from one applicant to another, therefore, only those activities to be performed under the scope of an applicant s TSSA Certificate of Authorization are required to be addressed in the QC Manual. TSSA survey teams are advised that this guide may not outline all possible aspects of each survey. The QC Manual need not follow the format of this guide. Questions of possible need for Interpretation raised by survey team members or the applicant shall be submitted to the TSSA Chief Inspector for an answer, and when submitted by the applicant a copy of the inquiry and reply should be provided by the inquirer to the applicant s Inspection Agency and any known involved enforcement authority. HOW TO USE THIS GUIDE Review each checklist item in the checklist against the QC Manual and: 1) Check ( ) the applicable column - Yes, No or N/A (Not Applicable) 2) Note the paragraph number in the QC Program Manual which covers the subject addressed in the column labelled Quality Program. Submit one copy of the completed checklist with one controlled copy of the QC Manual to TSSA Head Office for review, at least one month prior to the scheduled implementation review date. 2 of 11
