Each suspension wire shall not hang more than one in six out of plumb unless a countersloping wire or horizontal bracing is provided. This practice covers the installation of suspension systems for acoustical tile and lay-in panels. There are no additional seismic requirements. Hanger wires shall be gage and spaced feet on center or gage spaced feet on center. Any connection device at the supporting construction shall be capable of carrying not less than 1pounds.

Attachment of the bracing wires to the structure above and to the main runners shall be adequate for the load imposed. Here APPENDIX R ACOUSTICAL TILE AND LAY-IN PANEL CEILING. Suspended Ceiling Astm C6C6Detail. Tensile Strength (Ksi) max.

This is why the Seismic Design Category information is on the structural drawings. Installation should be done only when the temperature and humidity are within those stated in the product warranty. Special attention should be given to proper ventilation of the plenum, especially in high-moisture areas. Determine the place where the sprinkler head will be located. The standard bracket SFO- 24-BKTis inches (600mm) long and shall be mounted on the inch (600mm) ceiling grid.

The result of this mathematical equation is the maximum amount of deflection that is allowed under ASTM C636. LIGHT LOSS FACTOR (LLF) Used to calculate illuminance loss after a given period of time and under given conditions, such as, expected lamp light depreciation, expected lamp burn out, room surface dirt accumulation and ballast.

UpCodes offers a consolidated resource of construction and building code grouped by jurisdiction. Each vertical wire shall be attached to the ceiling suspension member and to the support above such that the wire loops shall be tightly wrapped and sharply bent to prevent any vertical movement or rotation of the member within the loops. UNIFIED FACILITIES GUIDE SPECIFICATIONS. While the practices described in this document have equal application to rated fire-resistive suspension systems, additional requirements may have been imposed to obtain the fire endurance classification of particular floor-ceiling or roof-ceiling assemblies. Clips may be used in lieu of spreader bars when approved by the City of Bellevue prior to installation.

ASTM C6is the standard for manufacturer’s grid design. ASTM C64 the installation requirements set by ASTM C75 and the specification of fire-rated partitions. International Building Code. The width of the perimeter supporting closure angle shall be not less than inches.
