Revisions to CIPs are facilitated by the NRMCA Research Engineering and Standards (RES) Committee to ensure that current information is covered.

CIPs are available in sets of individual topics, collated sets and special series sets. Topics can be viewed and purchased here.For more information, contact Jacques Jenkins at or 240-485-1165.
