4.1 Knowledge of hardness is useful in the development and the quality control of acoustical tile and lay-in ceiling panels. Deviation from an established hardness range will assist in pointing out processing errors or defective raw materials, thereby aiding the maintenance of uniform product quality. 4.2 This property is also useful in comparing the relative abilities of materials to resist indentations on the panel surface caused by impacts. 4.3 Since the hardness varies with the thickness, only samples of the same thickness shall be directly compared. 1.1 These test methods cover the determination of the strength properties of prefabricated architectural acoustical tile or lay-in ceiling panels as follows: Tests Sections Hardness 4 to 9 Friability 10 to 16 Sag 17 to 23 Transverse strength 24 to 30 1.2 Not all of the tests described in these test methods are necessary to evaluate any particular product for a specific use. In each instance, it is necessary to determine which properties are required. 1.3 These test methods specify procedures that are used in product development, manufacturing control, specification acceptance, and service evaluation. 1.4 Properties determined by these test methods reflect the performance of the materials under the specific conditions of the test, and do not necessarily indicate performance under conditions other than those specified herein. 1.5 The values stated in either SI units or inch-pound units are to be re......

4.1 The sound absorption of a material that covers a flat surface depends not only on the physical properties of the material but also on the way in which the material is mounted over the surface. The mountings specified in these practices are intended to simulate in the laboratory conditions that exist in normal use. 4.2 Some of the specified mountings require special fixtures or minor deviations from normal practice. These fixtures or deviations are to be used only during laboratory tests and should not be specified for practical installations. They are noted in the specifications for the mountings in question by the phrase “for laboratory testing only.” 4.3 Test reports may refer to these mountings by type designation instead of providing a detailed description of the mounting used. 1.1 These practices cover test specimen mountings to be used during sound absorption tests performed in accordance with Test Method C423. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
