All ANSI/RESNET American National Standards (ANS) are under Continuous Maintenance in accordance with Section 10.9 of the RESNET ANSI Standards Development Policy and Procedures. All portions of the standards are open to revision and any person may submit amendment proposals. Proposals are submitted to the RESNET Manager of Standards using the online form on the webpage, Submitting Proposed Amendments to Approved ANSI/RESNET Standards and Proposed New Candidate ANSI/RESNET Standards. Proposals will be reviewed by the Standards Management Board (SMB) to determine if they are critical. Critical proposed revisions will be assigned as a New Work Item to a Standards Development Committee (SDC) immediately. Proposals not determine critical will be assigned to the SDC at the time of the next update of the respective standard. RESNET standards are updated a minimum of every five years. Interested parties may also propose new standards in accordance with the RESNET ANSI Standards Development Policy and Procedures using the online form on the webpage, Submitting Proposed Amendments to Approved ANSI/RESNET Standards and Proposed New Candidate ANSI/RESNET Standards. Proposals will be reviewed by the Standards Management Board to determine if a proposed new standard fits within the scope of standards RESNET wants to develop. If the proposal is accepted, a New Work Item (NWI) be will assigned to the Standards Development Committee (SDC) for development. Affected parties may request interpretation of RESNET’s consensus standards in accordance with RESNET procedures using the Consensus Standards Interpretation Request form. Interpretation Requests (IRs) are submitted to the Manager of Standards (rick.dixon@resnet.us). The Manager of Standards then forwards the request to the Standards Development Committee responsible for maintaining the standard to be interpreted. Interpretations are determined by a consensus of the SDC. Suggestions and Questions? RESNET Standard development is a key activity of our organization. We are very interested in hearing suggestions on how to improve our process. If you have a suggestion or question about the development of RESNET Standards send it to RESNET Staff using the form below.
