4.1 A major concern for administration officials is security of barriers used in detention/correctional facilities. These test methods are designed to identify the security levels for ventilation grilles mounted within these barriers.

4.2 The purpose of these tests is to approximate levels of abuse to which grilles will potentially be subjected in the field, and to provide assurance of protection to the public, facility administrative personnel, and inmates.

1.1 These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of ventilation grilles used in secure areas, including detention and correctional facilities. The testing equipment provides for the setup and testing of specimen grilles and mounting systems. It is recognized that, in order to meet the intent of these test methods, ventilation grilles must be compatible with the level of performance require by Test Methods F2322.

1.2 It is the intent of these test methods to ensure that security ventilation grilles meet minimum performance levels to control the passage of unauthorized materials into secure areas, to confine inmates, to resist vandalism, and to delay or frustrate escape, or both. It is also the responsibility of the user of these test methods to insure that the grille selected is appropriate, based on relevant regulatory, health, and safety concerns and requirements. Such concerns include, but are not limited to, injury and suicide avoidance. These test methods do not quantify such concerns.

1.3 Take care to provide access to return and exhaust ducts for cleaning as required by NFPA 90A. If access cannot be provided though an interstitial space behind walls or ceiling, the use of filter grilles needs to be considered as an option. When filter grilles are provided, filters shall have a minimum UL-900 class 2 rating, and a filter replacement program needs to be in place at the facility.

1.4 Airflow performance shall be catalogued in accordance with ASHRAE 70–91. Manufacturer’s catalog data must include grade level achieved.

1.5 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.

1.6 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.

1.7 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.
