Introduction

  28 This part provides detailed information and documentation requirements and evaluation criteria to assist the Submitter to conduct a self-assessment that the rules conform to the Tier II functional requirements of the Standards, as outlined in part A. It includes a statement of intent, information and documentation requirements, and evaluation criteria for each Tier II functional requirement. Additionally, the information and documentation requirements and evaluation criteria serve as the audit standard for the GBS Audit Team.

  29 The statement of intent links Tier II functional requirements to Tier III verification criteria by providing an overview of what the verification of the particular functional requirement should achieve.

  30 The information and documentation requirements establish specific items that should be included and addressed in the submission supporting the verification.

  31 The evaluation criteria should be considered as the basis for conducting the self-assessment and audit.

  32 The rules, as referred to in this part, include the rule set, guidelines, interpretations, internal procedures, etc.

  33 Justification means providing the supporting data, analysis or other study that demonstrates the adequacy of the methodology, process or requirement. It should include: (1) basis for the assumptions made; (2) description of the uncertainties associated with them; and (3) any sensitivity analyses carried out. It includes documented rationale on which the validity of the hypothesis or criteria used in the requirements or calculations are based. These may be the results of research work, historical data, statistics, etc. For example, justification of safety factors should describe how the many related assumptions and uncertainties, such as environmental conditions, loads, structural analysis methodology and strength criteria, are accounted for.

  34 Where commentary or data are requested, it is sufficient for such information to be contained in a rule commentary or other supporting documentation.

  35 Where the rules establish a process to evaluate and accept alternatives, the submission should clearly identify the process for determining that an equivalent level of safety is achieved.
