1.1 这些测试方法测量开窗产品元件的阻力，如操作（或可拆卸）窗扇、防风窗扇和滑动玻璃门板（以下简称窗扇构件），以抵抗可能使建筑脱釉的力。 1.2 这些测试方法利用施加在窗扇构件内侧的集中载荷，模拟正常的打开和关闭力。可拆卸窗扇被加载以模拟拆卸和清洁的操作。 1.3 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 在正常使用情况下，当窗扇元件打开、关闭或从框架中抬起时，脱釉载荷通常平行于玻璃材料的平面施加，并偏心于窗扇元件。 当存在操作硬件时，扭转力可能会增加。打开和关闭力通常仅从内侧施加。滑动玻璃门板从两侧启动。 4.2 开窗产品抵抗脱胶力的能力可能因多种因素而异。在选择试样或解释试验结果时，应考虑这些因素。新组装的窗扇中的垫层化合物可能要经过几天或几周的固化才能达到完全强度。一些窗扇材料在低温下会收缩，在高温下会增加弹性。因此，由于温度条件的变化，含有这些材料的窗框可能会表现出一系列的抗脱釉性能。 窗框构件和玻璃材料的正常制造公差和间隙也可能影响抗脱胶性。此外，尽管开窗产品的设计是在一定的力限制范围内运行，但安装不当、磨损和滥用可能会增加窗扇运行所需的力。 4.3 在确定给定窗扇的哪些构件应进行抗脱胶试验时，必须考虑窗扇在正常安装时的操作方式。手柄和升降装置通常位于窗扇上，以方便操作员，因此决定了正常的操作方向。 4.4 试验方法A介绍了一种实际测量单个窗框构件脱粘力的技术。 4.5 试验方法B介绍了一种测量两个相对构件脱粘力的技术。本试验方法用于质量控制测量。

1.1 These test methods measure the resistance of elements of fenestration products such as operating (or removable) window sashes, storm sashes, and sliding glass door panels (hereafter referred to as sash members) to forces tending to deglaze the construction. 1.2 These test methods utilize concentrated loads applied to the interior side of a sash member in a manner simulating normal opening and closing forces. Removable sashes are loaded to simulate handling for removal and cleaning. 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. 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. ====== Significance And Use ====== 4.1 Under normal usage, deglazing loads are generally applied parallel to the plane of the glazing material and eccentric to the sash element when it is opened, closed, or lifted out of the frame. When operating hardware is present, torsional forces may be increased. Opening and closing forces are normally applied from the interior side only. Sliding glass door panels are activated from both sides. 4.2 The ability of fenestration products to resist deglazing forces may vary with a number of factors. These factors should be considered when selecting test specimens or when interpreting test results. Bedding compounds in newly assembled sashes may not reach full strength until they have been allowed to cure for several days or weeks. Some sash materials are subject to shrinkage at low temperatures and increased elasticity at high temperatures. Therefore, a sash containing these materials may exhibit a range of deglazing resistance due to varying temperature conditions. Normal manufacturing tolerances and clearances in sash members and glazing materials may also affect deglazing resistance. Further, although fenestration products are designed to operate within certain force limits, improper installation, wear, and abuse may increase the forces necessary for sash operation. 4.3 When determining which members of a given sash shall be tested for deglazing resistance, consideration must be given to the manner in which the sash may be operated when normally installed. Handles and lift devices are usually located on the sash for the convenience of the operator and therefore dictate the normal direction of operation. 4.4 Test Method A presents a technique for actual measurement of the deglazing forces of an individual sash member. 4.5 Test Method B presents a technique for measuring the deglazing force of two opposite members. This test method is intended for quality control measurements.
