These specifications have been prepared in accordance with the CSI recommended format with Part 1-General, Part 2-Product and Part 3-Execution. Guide specifications are intended to be used as the basis for developing job specifications and must be edited to fit specific job requirements. Inapplicable provisions should be deleted, appropriate selections should be made where there are choices, and provisions applicable to the job should be added where necessary. Options are shown in brackets. Notes, recommendations and instructions to specifiers are given in Italics directly following or at the start of the sections to which they apply. Notes that contain permissive language are not considered part of this standard. Dates given with ASTM and other standards were current at the time this specification was published. When a more recent standard is available, the specifier should verify its applicability to this Guide prior to its inclusion. Note: While the CSI Section Format locates Delivery, Storage and Handling in Part 1, NAAMM standards include them under Part 3 – Execution.
These specifications are comprehensive in regard to steel swinging sound control doors, door frames, sidelight, transom, and fixed window assemblies only. They do not cover sliding sound control doors or other related components. Due to the complexity of the field of acoustics, it is advisable to retain an acoustical consultant or acoustician.
Materials and fabrication methods are specified in detail in Part 2. Specific internal door constructions are not covered since they are proprietary to each manufacturer. Doors and frames made in accordance with these specifications have successfully met the testing and performance requirements of Section 1.05. However, the materials and fabrication methods called for in these specifications, while providing an excellent guide, are not meant to restrict the use of other materials and methods where it can be demonstrated through the specific testing procedures in Section 1.05 that the construction can equal or exceed the performance levels specified in this section. In order to ensure that a manufacturer's product meets the desired performance levels, the construction specifications must always include the testing and performance requirements of Section 1.05 and the Quality Assurance requirements of Section 1.06. Note: the effectiveness of a door and frame unit is dependent on the sum of all parts of the unit functioning effectively in order to meet the specified STC rating. This would mean that all portions of the unit including the door, doorframe, perimeter gaskets and glazing are tested as a unit. All components must be supplied from a single source, with the exception of glazing which may be factory installed or field installed by the manufacturer's authorized representative.
