1.1 本规程描述了破坏性和非破坏性程序。 1.2 破坏性程序对密封剂施加应力，从而导致密封剂的内聚或粘合失效，或在存在缺陷基质条件的情况下导致基质的内聚失效。目的是通过施加与密封剂涂条承受其最大公布移动能力（如已知）时可能经历的应变相关的应变来表征密封剂在特定基材上的粘附/内聚性能；或在运动能力未知时的合理应变。施加在密封剂涂条上的应变可能不会导致密封剂或基材失效、在影响密封剂失效之前缺陷基材失效或密封剂失效。 注1: 破坏过程需要立即修复密封胶涂条。 为此，应提供适当的材料和设备。 注2: 当正确安装并使用该方法进行评估时，密封剂配方可能在内聚性或附着力方面失败。应咨询密封剂制造商，以确定使用该方法的适当指南。 1.3 无损检测程序会在密封剂上施加应力，并在粘合剂上施加应力。虽然该程序被称为非破坏性程序，但可能会导致缺陷密封剂涂条的粘合失效，但不应导致密封剂的内聚失效。该程序的结果应为粘合剂失效或无失效。 注3: 如果密封剂出现故障，则无损检测程序可能需要立即修复密封剂涂条。为此，应提供适当的材料和设备。 1.4 无损检测程序可用于100%密封剂涂条的连续检测，或用于任何不符合指南惯例的缺陷条件区域 C1193 ，是可疑的。 1.5 对此做法具有管辖权的委员会不知道其他组织或委员会发布的任何类似做法。 1.6 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 许多参数有助于密封剂应用的整体性能。一些最重要的参数是密封胶条尺寸和配置、接头移动、工艺质量、粘合剂粘结质量和密封胶材料质量。 4.2 当密封剂发生内聚或粘合失效时，通常不能起到防风雨密封的作用。 4.3 如果密封剂涂条失效，则可能需要评估接缝的总移动，以确定接缝密封剂的应变是否超出其预期设计，或者密封剂是否在设计参数内失效。 4.4 如果密封剂涂条粘附失败，则没有直接的程序来确定原因。粘合剂失效可能是由于工艺、使用的特定表面处理、使用的特定密封剂、“安装”接头设计不佳、粘结化学性差和其他原因造成的。 4.5 由于密封剂涂条性能的复杂性，了解粘合剂的质量有助于评估密封剂性能。重要的是，使用的评估程序要真正评估粘合剂的质量，而不是简单地利用密封剂的抗撕裂性。 4.6 该方法不评估密封剂涂条作为防风雨密封的性能。它仅评估与特定装置中密封剂的内聚强度相关的粘接特性。由于使用这些程序导致的任何故障都是故意引起的，因此它们不一定意味着密封剂涂条不会起到防风雨密封的作用。 4.7 这些方法的结果在识别粘附性差的密封胶珠时最为有用。连续检查程序也有助于识别接头配置不良的位置。 还发现了明显的内聚失效。这些方法的结果可用于评估密封剂涂条的可能性能，并比较不同基材制备和密封剂材料的附着力。 4.8 当密封剂由于温和或低温而处于延伸状态时，非破坏性方法最有效。当密封剂处于压缩状态时，它们在高温下最不有效。

1.1 This practice describes destructive and non-destructive procedures. 1.2 The destructive procedure stresses the sealant in such a way as to cause either cohesive or adhesive failure of the sealant or cohesive failure of the substrate where deficient substrate conditions exist. The objective is to characterize the adhesive/cohesive performance of the sealant on the specific substrate by applying a strain that correlates to the strain that the sealant bead may experience when subjected to its maximum published movement capability, when known; or a reasonable strain when the movement capability is unknown. It is possible that the strain applied to the sealant bead may result in no failure of the sealant or the substrate, failure of a deficient substrate before effecting a failure in the sealant, or a failure of the sealant. Note 1: The destructive procedure requires immediate repair of the sealant bead. Appropriate materials and equipment should be available for this purpose. Note 2: Sealant formulations may fail in cohesion or adhesion when properly installed, and evaluated by this method. The sealant manufacturer should be consulted to determine the appropriate guidelines for using this method. 1.3 The non-destructive procedure places strain on the sealant and a stress on the adhesive bond. Though termed non-destructive, this procedure may result in an adhesive failure of a deficient sealant bead, but should not cause a cohesive failure in the sealant. The results of this procedure should be either adhesive failure or no failure. Note 3: The non-destructive procedure may require immediate repair of the sealant bead, if sealant failure is experienced. Appropriate materials and equipment should be available for this purpose. 1.4 The non-destructive procedure can be used for continuous inspection of 100 % of the sealant bead(s), or for any areas where deficient conditions, which are inconsistent with the practices of Guide C1193 , are suspected. 1.5 The committee with jurisdiction over this practice is not aware of any comparable practices published by other organizations or committees. 1.6 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. 1.7 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. ====== Significance And Use ====== 4.1 Many parameters contribute to the overall performance of a sealant application. Some of the most significant parameters are sealant bead size and configuration, joint movement, quality of workmanship, the quality of the adhesive bond, and the quality of the sealant material. 4.2 A sealant usually fails to perform as a weatherseal when it experiences cohesive or adhesive failure. 4.3 If a sealant bead fails, an evaluation of the total joint movement may be needed to determine if the joint sealant was strained beyond its intended design, or if the sealant failed within the design parameters. 4.4 If a sealant bead fails adhesively, there is no straightforward procedure for determining the cause. The adhesive failure may be due to workmanship, the specific surface preparation used, the specific sealant used, poor “installed” joint design, poor bond chemistry and other causes. 4.5 Because of the complex nature of the performance of a sealant bead, an understanding of the quality of the adhesive bond is instrumental in any evaluation of sealant performance. It is critical that the evaluation procedures used truly evaluate the quality of the adhesive bond and do not simply take advantage of the tear resistance of the sealant. 4.6 This method does not evaluate the performance of a sealant bead as a weatherseal. It only evaluates the characteristics of the adhesive bond relative to the cohesive strength of the sealant in a particular installation. Since any failures that result from use of these procedures are intentionally induced, they do not necessarily mean that the sealant bead will not perform as a weatherseal. 4.7 The results of these methods are most useful in identifying sealant beads with poor adhesion. The continuous inspection procedure is also useful in the identification of places of poor joint configuration. Obvious cohesive failures are also identified. The results of these methods can be used to assess the likely performance of the sealant bead and to compare the adhesion of different substrate preparations and sealant materials. 4.8 The non-destructive methods are most effective while the sealant is in a state of extension due to mild or low temperatures. They are least effective during high temperature when the sealant is in a compressed condition.
