ASTM E557-12(2020) pdf free download.Standard Guide for Architectural Design and Installation Practices for Sound Isolation between Spaces Separated by Operable Partitions.
ASTM E557-12(2020) provides design details that should be considered in the design of buildings that include operable partitions. Operable partitions are those that can be quickly put in place or removed and stored to provide flexibility in the size of spaces typically used for meetings or social functions.
4.1 There are several types of operable partitions: hinged
panel groups, individual panel and continuously hinged parti- tion systems. Some are supported by overhead track with or without a floor guide or track. Some are floor supported with an overhead track to guide them. They may be manual or power-operated. One type consists of movable panels secured in place by vertical expansion to seal against the floor and ceiling.
4.2 Several factors should be considered in specifications:
4.2.1 Seals or gaskets are of many kinds; some consist of resilient material that maintains continuous flexible contact with floor or ceiling, and some include a mechanical, hydraulic or pneumatic mechanism that maintains clearance when in motion and a positive seal when finally closed. The seals at the top of the partitions should make continuous contact with smooth surfaces on both sides of the operable partitions. The sound path through an insufficient seal, up and over the track. and out on the other side through the insuficient seal consti tutes a serious sound leak.
4.2.3 Pass-through doors in partitions will generally reduce the overall sound isolation of the wall. For this reason,pass-through doors should be equipped with full perimeter gasketing, including seals at head.
4.2.4 Track assemblies installed outside the partition storage pocket area to form cross-through paths primarily for the transport of partitions from one location to the other should be avoided unless a satisfactory method is provided to reduce the flanking path created through the track section from one side of the partition to the other.
