4.3 Nomenclature for joints
The joint systems are identified by an alphanumeric identification system . The first two alpha characters identify the type of joint system . The third alpha character is either S or D . The S ( static ) signifies joint systems that do not have movement capabilities . This D ( dynamic ) signifies joint systems that do have movement capabilities . The numeric component uses sequential numbers to identify the nominal width of the joint systems .
HW - D - 0 034
Barriers that form the joint FF = Floor-to-Floor WW = Wall to Wall FW = Floor to Wall HW = Head of Wall
Movement – Static or Dynamic ? D = Dynamic ( movement capabilities ) S = Static ( nomovement capabilities )
Individual System Number
Joint width 0000 – 0999 = joint ≤ 2 inch 1000 – 1999 = joint > 2 inch ≤ 6 inch 2000 – 2999 = joint > 6 inch ≤ 12 inch 3000 – 3999 = joint > 12 inch ≤ 24 inch 4000 – 4999 = joint > 24 inch
