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
