For over 50 years, the Rack Manufacturers Institute (RMI) has been evolving consensus standards for industrial steel storage racks. In 2012 the industry developed its latest and most comprehensive consensus document RMI/ANSI MH16.1 - 2012. The document includes seismic design provisions and has been accepted as the default standard for the International Building Code and NFPA Building Codes. RMI has further developed the National Standard for welded wire rack decking which has been adopted as RMI MH26:2-2007. Both documents serve as baseline specifications for the R-Mark Certification Program. The following companies hold an active R-Mark License:
Members of RMI have voluntarily chosen to be guided by the appropriate RMI/ANSI standards. RMI members have further voluntarily agreed to a certification process administered through a panel of independent Registered Professional Engineers. The R-Mark Certification represents one leg of a 3-legged stool - the others being Consensus Standards and Conformity. Initiatives in all three areas are part of a focused strategic objective launched in the early 1990's. The purpose of this overview is to speak specifically to the R-Mark "leg". Suffice it to say that all three "legs" are critically dependent on one another. R-Mark is a registered asset of the Rack Manufacturers Institute (RMI) and is offered under license to members and non-members who are proven to meet certain requirements.
In developing consensus on a process, a number of guiding principles were followed. Process must be:
General operating characteristics of the Program include:
Highlights of the Certification and Licensing process follow:
The process is voluntary and is open to all rack manufacturers. RMI encourages specifiers and users of Industrial Steel Storage Rack to consider the value of R-Mark certification when applying racking solutions.
