******************************************************************************

A. Partition system shall have components which can be disassembled, relocated, and substantially

reused. System shall consist of vertical gypsum board panels, floor runner, top rail, splice

studs, trim, and

accessories. Partition shall be [3-3/8] [4-1/2] inches thick and provide 1-7/8 inches wide

cavity for distribution of utilities.

******************************************************************************

If including performance specifications, edit Section carefully to avoid conflict between descriptive and

performance requirements. Refer to USG product literature and test reports for design requirements and

limitations of each performance rating. Coordinate partition performance with specifications for

doors, glazing, penetrations through partitions, and perimeter construction.

******************************************************************************

1.05 PERFORMANCE

******************************************************************************

UL U427 (One-Hour) requires "H" or "T" studs at 24 or 30 inches on center. UL U416 (Two-Hour) requires

[____________________________.]

******************************************************************************

42 STC can be obtained with steel "H"-studs located 24 inches on center. Other studs or spacings may

result in lower ratings. Cavity insulation can be used to obtain higher ratings. Partitions constructed

according to UL U416 provide 50 STC. See test reports for additional requirements.

******************************************************************************

B. Sound Transmission Classification: [42] [50] [________] STC tested in accordance with ASTM E90

perpendicular to the partition without exceeding deflection of 1/240 of the partition

height.

2. System shall withstand five 30 ft. lb. impacts with no observable damage. Instantaneous

deflection shall be one inch max., permanent deflection set shall be 0.10 inch max.

Test in vertical position.

D. Surface Impact Resistance: Gypsum panels shall not fracture or break, and no indentation greater

than 1/16 inch measured 24 hours after impact from an 8 oz., 1-1/2 inch diameter steel ball

dropped from a height of 18 inches; Federal Test Method Standard No. 406, Method 1074.
