    Abstract

    This specification covers the various sizes of round opening perforated plates and screens for general industrial uses, including the separating or grading of materials according to designated nominal particle size, and lists standards for openings punched with various bar sizes and thicknesses of plate for various grades of service. This specification does not apply to perforated plates or screens with square, hexagon, slotted, or other shaped openings.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers the sizes of round opening perforated plate and screens for general industrial uses, including the separating or grading of materials according to designated nominal particle size, and lists standards for openings from 5 in. (125 mm) to 0.020 in. (500 μm) punched with bar sizes and thicknesses of plate for various grades of service. Methods of checking industrial perforated plate and screens are included as information in Appendix X3.

    1.2 This specification does not apply to perforated plate or screens with square, hexagon, slotted, or other shaped openings.

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    1.4 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.
