ASTM C635/C635M-2017吸音砖和镶板天花板金属悬挂系统的制造, 性能和试验的标准规格

1.1x00a0;This specification covers metal ceiling suspension systems used primarily to support acoustical tile or acoustical lay-in panels. 1.2x00a0;Some suspension systems incorporate locking assembly details that enhance performance by providing some continuity or load transfer capability between adjacent sections of the ceiling grid. The test methods of Test Methods E3090/E3090M referenced in this specification do not provide the means for making a complete evaluation of continuous beam systems, nor for assessing the continuity contribution to overall system performance. However, the test methods can be used for evaluating primary structural members in conjunction with secondary members that interlock, as well as with those of noninterlocking type. 1.3x00a0;While this specification is applicable to the exterior installation of metal suspension systems, the atmospheric conditions and wind loading require additional design attention to ensure safe implementation. For that reason, a specific review and approval should be solicited from the responsible architect and engineer, or both, for any exterior application of metal suspension systems in the construction of a new building or building modification. 1.4x00a0;The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5x00a0;The following safety hazards caveat pertains only to the test methods described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C636/C636M-2019隔音砖和铺设板用金属天花板悬挂系统安装的标准操作规程

1.1x00a0;This practice covers the installation of suspension systems for acoustical tile and lay-in panels. It is applicable to contractors whose services are utilized for installing acoustical ceilings and to other trades if their activities are responsible for interference with ceiling components or performance as defined in this recommended practice. 1.2x00a0;While the practices described in this document have equal application to fire-resistive suspension systems, many systems impose additional requirements to obtain the fire endurance classification of particular floor-ceiling or roof-ceiling assemblies. These details are available from the listing agency and from the manufacturers. 1.3x00a0;Similarly, additional detailing is often necessary to meet sound attenuation requirements when ceiling plenums extend over contiguous rooms. Obtain these from the manufacturer of the acoustical material employed. 1.4x00a0;The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems result in non-conformance with the standard. 1.5x00a0;While many of the practices described in this practice have application to the installation of metal suspension systems in exterior environments, the specific design of exterior ceiling installations requires the review and approval of the architect or engineer, or both, who are responsible for the construction of the building or modifications to an existing building. While recommendations from the manufacturer are solicited, it remains the final responsibility of the architect/engineer to ensure proper application of the materials in question. 1.6x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5x00a0;The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard 1.6x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate standard safety and health practices and determine the applicability of regulatory limitations prior to use. 1.7x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1x00a0;Load Carrying Capacity:x00a0; 4.1.1x00a0;Most architectural specifications contain a uniform load requirement based on Specification C635. Additionally, it is useful to know the uniform loads of cross runners to evaluate their suitability for various ceiling loads. 4.1.2x00a0;The procedure detailed in this standard is intended to be used for the simple four foot span specified in Specification C635. It can be used for simple spans other than four feet, but an engineering analysis is required to determine the proper spacing of concentrated loads necessary to simulate a uniform load. 4.1.3x00a0;Various concentrated load combinations can be similarly tested or they can be calculated from the uniform load results by engineering analysis. 4.2x00a0;Connection Strength in Tension and Compression:x00a0; 4.2.1x00a0;Structural failure of grid systems under axial loading is controlled by the failure of connections between the grid members. Specification of the allowable axial loads is useful for designers and specifiers for determining which grid systems will be appropriate for specific job conditions. 4.2.2x00a0;Connection strength is particularly important where the grid installation is expected to experience lateral loads due to earthquake or wind. 4.2.3x00a0;Connection strength in both compression and in tension are specified in Practice E580 as mean ultimate test load in tension and in compression. 1.1x00a0;These test methods cover metal ceiling suspension systems used primarily to support acoustical tile, acoustical lay-in panels, or suspended T-bar type ceiling systems. 1.2x00a0;These test methods cover the determination of strength properties of suspended ceiling grid system components as follows: Tests Subsections Load Carrying Capacity 5.1 Connection Strength in Tension 5.2.2; 5.2.4 Connection Strength in Compression 5.......
