1、Designation: F2542 05 (Reapproved 2012)Standard Test Methods forPhysical Assault on Ventilation Grilles for Detention andCorrectional Facilities1This standard is issued under the fixed designation F2542; the number immediately following the designation indicates the year oforiginal adoption or, in t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover requirements for simulatedservice tests and testing equipmen
3、t for determining the perfor-mance characteristics of ventilation grilles used in secure areas,including detention and correctional facilities. The testingequipment provides for the setup and testing of specimengrilles and mounting systems. It is recognized that, in order tomeet the intent of these
4、test methods, ventilation grilles mustbe compatible with the level of performance require by TestMethods F2322.1.2 It is the intent of these test methods to ensure thatsecurity ventilation grilles meet minimum performance levelsto control the passage of unauthorized materials into secureareas, to co
5、nfine inmates, to resist vandalism, and to delay orfrustrate escape, or both. It is also the responsibility of the userof these test methods to insure that the grille selected isappropriate, based on relevant regulatory, health, and safetyconcerns and requirements. Such concerns include, but are not
6、limited to, injury and suicide avoidance. These test methods donot quantify such concerns.1.3 Take care to provide access to return and exhaust ductsfor cleaning as required by NFPA 90A. If access cannot beprovided though an interstitial space behind walls or ceiling,the use of filter grilles needs
7、to be considered as an option.When filter grilles are provided, filters shall have a minimumUL-900 class 2 rating, and a filter replacement program needsto be in place at the facility.1.4 Airflow performance shall be catalogued in accordancewith ASHRAE 7091. Manufacturers catalog data must in-clude
8、grade level achieved.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafety c
9、oncerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
