ASTM E497-99 PDF

1.1 This practice covers measures intended to prevent situations or conditions that will detract from the sound-insulating properties of acoustically-rated lightweight partitions. It is not intended to include all sound insulating constructions. Many acoustically-rated partitions are also fire rated and when being installed must be built in accordance with the construction details specified in the fire test construction. In any event, applicable building codes and regulations should be checked for possible conflicts.

1.2 Excluded from this scope are masonry type partitions having all or part of their construction from brick, concrete block, aggregate block, plaster block, poured concrete, etc. Also excluded are operable and demountable partitions (Operable are those partitions with a mechanism for easy movement; demountable partitions are those which are designed and installed with the intent of later being taken down and re-erected by a crew over a period of time, with the components being reusable). Not excluded are those partitions which are lightweight but have thin brick, tile, or plaster on one or both faces.

1.3 Plumbing wall and kitchen problems are excluded from this document.
