Tier 1 material becomes part of the design certification rule and may be changed only by rule-making. Tier 2 - The design-related information contained in the DCD that is not Tier 1 information. It supports the certification of a standard design by providing additional details about the proposed implementation. The Tier 2 information generally consists of the SAR with the proprietary information removed for purposes of rule-making.
