These specifications have been prepared in accordance with the CSI recommended format with Part 1- General, Part 2-Product and Part 3-Execution. Explanatory notes or instructions are shown in italics. 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. Optional items or requirements are shown in brackets. Notes and instructions to specifiers are given in italics directly following the paragraphs to which they apply. Dates given with ASTM and other standards were current at the time this specification was published. Specifier should use the latest dates when preparing job specifications.
Materials and fabrication methods are specified in detail in Part 2. Doors and frames made in accordance with these specifications have successfully met the testing and performance requirements of Paragraph 1.06. However, the materials and fabrication methods called for in these specifications, while providing a sound guide, are not meant to restrict the use of other materials and methods where it can be demonstrated through the specific testing procedures in Paragraph 1.06 that the construction can equal or exceed the performance levels specified in this paragraph. 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 Paragraph 1.06 and the quality requirements of Paragraph 1.07.
These guide specifications are limited to applications where traffic is relatively light and hard usage is not anticipated. For doors that do not fall into this category it is strongly recommended that NAAMM Standard HMMA 861, Guide Specifications for Commercial Hollow Metal Doors and Frames be used. If security is a factor there are two hollow metal standards available, NAAMM Standard HMMA 862, Guide Specifications for Commercial Security Hollow Metal Doors and Frames and NAAMM Standard HMMA 863, Guide Specifications for Detention Security Hollow Metal Doors and Frames. For acoustic applications consideration may be given NAAMM Standard HMMA 865, Guide Specification for Swinging Steel Sound Control Doors and Frames.
