4.1 A major concern for detention and correctional administrative officials is the reliable operation of sliding devices used in their facilities. These test methods aid in assigning a level of physical security and performance to devices for sliding door assemblies.4.2 These test methods evaluate the resistance of a sliding door assembly to attacks using battering devices, prying devices, smoke, and fire. These test methods also evaluate the performance of a sliding device under simulated operating conditions. These test methods do not provide a measure of the resistance or performance of the device subjected to attack by chemical agents, ballistics, explosives, or other extreme methods of attack. These test methods do not measure the resistance or performance of the device when subjected to environmental elements such as humidity, temperature, rain, snow, or wind-carried dust or sand. Where such elements may be a factor the manufacturer should be consulted for proper application.4.3 The primary purpose of these test methods is to approximate the levels of abuse and operating conditions to which devices are subjected in detention and correctional institutions. The result of these test methods will provide a measure of assurance of protection to the correctional personnel, public, and inmates.4.4 Preventative maintenance programs shall be provided in accordance with the manufacturer's recommendation to enable sliding device assemblies to function as intended throughout the expected service life.4.5 These test methods do not measure the performance or cycle life of the local or remote mechanical emergency release mechanism, or both, due to their design variables and low user requirements.1.1 These test methods cover the apparatus, procedures, and acceptance conditions for evaluating the normal operational performance and the performance characteristics under assault, smoke, and fire conditions of sliding device assemblies in detention and correctional institutions. These test methods give an indication of the performance characteristics of devices in actual service. Such variables as installation and maintenance conditions are not considered.1.2 It is the intent of these test methods to help ensure that detention sliding devices perform at or above minimum acceptable levels to control passage to unauthorized or secure areas, to confine inmates and to delay and frustrate escape attempts and resist vandalism. However, these test methods do not address door construction. It is recognized that in order to meet the intent of these test methods, door assemblies shall be compatible with the level of performance required by Test Methods F1450.1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.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.1.5 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.

4.1 Comparison of brake horsepower developed and of specific fuel consumption rates from engine to engine may be made by use of data based upon a standard for composition of an engine assembly.4.2 The purchaser of the engine assembly will be fully advised of the minimum scope of assembly which the purchaser may rightfully expect to be encompassed by a response to a request for quotation and to be delivered in response to a purchase order unless the engine builder in the proposal or in the offer to sell has clearly advised otherwise.4.3 It will be made apparent to the purchaser that additional auxiliary and accessory equipment will be needed to supplement the defined engine assembly when full consideration is given to the application of the engine assembly as a prime mover in a specific vessel.1.1 This guide covers performance and minimum scope of assembly of all medium speed marine diesel engines intended for main propulsion of single or multiple screw propelled marine vessels or for vessels using other than screw propeller-type main propulsion.1.2 This guide is intended to supplement the regulations of legally constituted regulating authorities. In the event of any conflict, which may become apparent after publication of this guide, with such legally constituted regulations, the latter shall take precedence, as may be applicable within the jurisdiction of such authorities and specific to each case, unless such latter regulations are formally waived by proper cognizant authority.1.3 This guide is not intended to relieve the purchaser of the obligation fully to advise the engine builder of all of the purchaser’s unique operational considerations to allow those considerations to be satisfied.1.4 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.

4.1 There are numerous flammability ratings and tests. Almost without fail, these standards and tests are focused on very specific industries or results, many of which are not applicable to the membrane switch/human machine interface assembly. This test is designed to provide relative results between membrane switches that have been assembled to the unit's final enclosure, housing, etc.4.2 In addition to the test's measurement of the rate of burn, a laboratory can also observe the effects of burning material falling from the test specimen onto other materials (typically a gauze test area) not directly part of the test specimen. The indirect burning is an issue of interest to see if the test specimen will be able to act as an initiator for a far greater and more damaging flame event (fire). Observations should be noted, as qualitative descriptions, as appropriate.4.3 This test can measure the flammability via the use of high-speed photographic or video equipment.4.4 Temperature of the ignition source can be measured via a calibrated thermocouple pyrometer, calorimeter or IR thermometer with an appropriate range.4.5 This test is not designed to provide a PASS or NO PASS status for a switch, rather, it is designed to provide a “grade” for the level of flammability of a membrane switch assembly (as defined in 3.1.10). The end user should make the final determination if the level of flammability is acceptable for the particular application.1.1 This test method covers the determination of the flammability characteristics of a membrane switch.1.2 This test method defines the MSB rating of a membrane switch. Each character of the MSB rating represents a discrete characteristic of a membrane switch performance under destructive thermal loading.1.3 This test procedure will be destructive, but should provide an insight into the relative performance flame-resistance characteristics of differing designs or assemblies, or both.1.4 This test method will focus on the use of convective contact (burner flame) method for ignition, though other methods of ignition are available.1.5 This test method is designed to determine if the membrane switch assembly will add (or detract) from the flame propagation from an exterior flame/fire source.1.6 If this test is intended to be used for an internal flammability source then set up the unit under test (UUT) appropriately and note it in the test scope and results.1.7 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.1.8 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.

When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured.5.4 This test method is not intended to be used as the only test method in the selection of a spandrel-panel assembly. It is not intended as a specification for all attributes required by a spandrel-panel assembly, or any of its individual components, in order for a spandrel-panel assembly to be used in a particular application.1.1 This test method evaluates the fire-test response characteristics of a spandrel-panel assembly spanning the intersection of a floor assembly.1.2 This test method is used to assess the spandrel-panel assembly’s ability to impede spread of fire to the interior of the room or the story immediately above it via fire spread from the exterior of a building, and provide a quantitative measure of the fire hazard in terms of an I-Rating, T-Rating, and F-Rating from a specified set of fire conditions involving specific materials, products, or assemblies.1.3 This test evaluates the performance of the portions of the exterior wall installed between vertically adjacent window openings in multi-story buildings.1.4 This test method addresses the potential for fire spread to a single story immediately above the room of fire origin.1.5 The test method simulates a fire in a post-flashover condition in a compartment that is venting to the exterior through a window opening.1.6 The fire exposure conditions within the test room are those specified by this test method for the first 30 min of exposure and then conform to Test Methods E119 time-temperature curve for the remainder of the test. The fire exposure on the exterior surface of the test specimen comprises both the exposure from the fire plume exiting the window opening of the test room and the exterior burner, although the fire exposure on the exterior surface of the test assembly is not equivalent to that of Test Methods E119.1.7 This test method specifies the heating conditions, methods of test, and criteria for evaluation of a building’s spandrel-panel assembly. Specimens are not tested using any super-imposed axial load.1.8 Test results establish the performance of the spandrel-panel assembly during the fire-exposure period and shall not be construed as having determined the suitability of a spandrel-panel assembly for use after that exposure.1.9 This test method does not provide quantitative information about the spandrel-panel assembly relative to the rate of leakage of smoke or gases, or both.1.9.1 This test method does not evaluate the fire-test-response characteristics of perimeter joint protection between the floor assembly and the exterior wall assembly. This is covered in Test Method E2307.1.10 This test method does not evaluate the fire-test-response characteristics or fire propagation propensity of material installed on, or within, exterior non-load-bearing wall assemblies containing combustible components. This is covered in NFPA 285.1.11 The values stated in inch-pound units are to be regarded as the standard. Where provided, the SI values given in parentheses are for information only.1.12 The text of this test method 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.1.13 This test method is used to measure and describe the response of materials, products or assemblies to heat and flame under controlled conditions but does not by itself incorporate all factors required for the fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.1.14 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.1.15 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.16 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.
