1.1这些试验方法包括在密封件制作后和冷却到环境温度之前，对柔性腹板热塑性表面之间形成的热密封件强度进行实验室测量。 1.2这些试验方法仅限于仪器化热粘性试验，要求试验机自动加热密封试样，并在密封循环结束后的精确测量时间立即确定热密封强度。另一个先决条件是，在密封顺序开始后，操作员不得影响试验。这些试验方法不包括使用弹簧、杠杆、滑轮和砝码的非仪器手动程序，其中试验结果可能会受到操作员技术的影响。 1.3这些试验方法中描述了仪器化热粘性试验的两种变体，主要在两个方面有所不同:（a）密封试样试验期间的夹持分离速率，以及（b）试验机是否产生受试材料的冷却曲线，或者测量在设定延迟时间后观察到的最大力。这两种试验方法均可用于测试这些试验方法范围内以及所用机器范围和容量内的所有材料。第4节对其进行了描述。 1.4首选国际单位制，并应在裁判决定中使用。 1.5本标准无意解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。设备操作员应注意密封钳口在一起形成密封时的夹点、钳口的热表面以及用于切割样本的锋利仪器。建议操作员审查设备供应商的安全预防措施。

1.1 These test methods cover laboratory measurement of the strength of heatseals formed between thermoplastic surfaces of flexible webs, immediately after a seal has been made and before it cools to ambient temperature. 1.2 These test methods are restricted to instrumented hot tack testing, requiring a testing machine that automatically heatseals a specimen and immediately determines strength of the hot seal at a precisely measured time after conclusion of the sealing cycle. An additional prerequisite is that the operator shall have no influence on the test after the sealing sequence has begun. These test methods do not cover non-instrumented manual procedures employing springs, levers, pulleys and weights, where test results can be influenced by operator technique. 1.3 Two variations of the instrumented hot tack test are described in these test methods, differing primarily in two respects: (a) rate of grip separation during testing of the sealed specimen, and (b) whether the testing machine generates the cooling curve of the material under test, or instead makes a measurement of the maximum force observed following a set delay time. Both test methods may be used to test all materials within the scope of these test methods and within the range and capacity of the machine employed. They are described in Section 4. 1.4 SI units are preferred and shall be used in referee decisions. 1.5 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 and health practices and determine the applicability of regulatory limitations prior to use. The operator of the equipment is to be aware of pinch points as the seal jaws come together to make a seal, hot surfaces of the jaws, and sharp instruments used to cut specimens. It is recommended that the operator review safety precautions from the equipment supplier.
