5.1x00a0;These test methods are intended to establish a measure of resistance for sliding door assemblies subjected to attacks (other than impacting glazing materials) by unskilled or opportunistic burglars. Resistance to higher levels of force generated by skilled burglary attack requires methods, such as alarms, communication, or apprehension systems, or special security glazing materials more sophisticated than those evaluated by these test methods. Technicians performing the test should understand the intent of this test method and should be trained on the execution and pass/fail criteria.
5.2x00a0;Entry through a sliding door assembly can be accomplished by impacting or removing glazing materials. This method does not evaluate glazing materials for breakage or de-glazing. Other standards must be used to evaluate forced entry by impacting or removing glazing.
5.3x00a0;Acceptance criteria for performance levels are a matter for authorities having specific jurisdiction to establish. Suggested guidelines are found in Annex A1.
1.1x00a0;These test methods determine the ability of sliding door assemblies to restrain, delay, or frustrate forced entry.
1.2x00a0;For purposes of these test methods, sliding door assemblies are defined as described in 1.2.1 x2013; 1.2.4 and as shown in Fig. 1. Sliding door assemblies with a combination of operable panels and fixed panels (lites) shall be classified and tested separately for each type.
1.2.1x00a0;Type Ax2014;A sliding door assembly which incorporates one or more sliding panels that lock to the jamb.
1.2.2x00a0;Type Bx2014;A sliding door assembly which incorporates one or more sliding panels that lock to an intermediate jamb.
1.2.3x00a0;Type Cx2014;A sliding door assembly which incorporates one or more sliding panels that abut and lock to other panels.
1.2.4x00a0;Type Dx2014;A sliding door assembly which incorporates one or more fixed or stationary panels that are designed not to open.
1.3x00a0;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.
1.4x00a0;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 o......
① 悬臂梁测试法将护目镜试样的一段夹在夹具中,计算冲击锤打破试样需要的能力,并计算出冲击强度。符合的国际测试标准包括ASTM D256 , ASTM D4182和ISO 810。冲击锤的能量范围为0.5焦耳至25焦耳。② 简支梁测试法简支梁测试需要将护目镜材料制作成标准试样,一种是U形缺口试样,一种是V形缺口试样。试验时将试样放在试验机两支座上,通过摆锤的冲击计算冲击吸收能量。...
*NIST夏比实验室有六台不同配置、不同能量水平的夏比试验机,既有用于高强度钢实验的1000焦耳(738尺磅)型号,也有用于小型夏比试样测量的台式装置。 **夏比冲击试验是一种摆锤冲击方法,最早由美国人Silas Bent Russell于1896年首创,后来由法国研究员Georges Augustin Charpy改进,后者提议将其作为ASTM标准。 ...
