1.1 本试验方法涵盖了人体内部核心温度、皮肤温度、热暴露时间、心率反应、耗氧量和全身出汗率的生理测量，以评估个人冷却系统（PCS）在减少热应激影响方面的有效性。 1.1.1 为了提高生理测试期间的安全性，这种动态测试需要使用表现出特定健康和身体素质要求的人类参与者。 1.2 本测试包括与个人电脑一起使用或穿在个人电脑顶部的防护服（外套）。 因此，该范围面向工业而非运动应用。 1.2.1 将使用相同的防护服套装对不同防护服的有效性进行量化。因此，获得的生理值仅适用于冷却系统、特定防护服和特定测试条件。 1.2.2 当未提供防护服时，本试验方法要求使用本试验方法中规定的标准外衣对PCS进行试验。 1.2.3 本标准不试图确定PCS或与PCS一起穿着的衣服的重要衣服特性，如隔热和耐蒸发性。 试验方法 F1291 和 F2370 可供这些服装测量参考。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 测试实验室有责任获得其机构要求的必要和适当的批准，以便使用人类参与者进行测试。 1.5 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。 1.6 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 本试验方法可用于量化和比较不同个人冷却系统（PC）与标准外套或指定防护外套搭配时提供的冷却。 4.1.1 该测试方法将基于对核心温度、平均皮肤温度、心率、暴露时间、耗氧量和全身出汗率的生理测量来评估PCS的性能。 4.2 评估过程控制系统的有效性是一项极其复杂的工作，涉及与过程控制系统、环境和参与者之间的热交换有关的许多因素。在这种范围的测试方法中，建立足以涵盖所有意外事件的细节是不现实的。因此，一种有效的测量核心温度的生理学方法以及热应变的其他变量，提供了一种可接受的分类PCS性能的方法。该测试方法还将测量PCS在指定的热应力条件下将核心温度保持在安全限值内的时间量。 4.3 偏离本试验方法中的说明可能会导致试验结果显著不同。需要掌握有关体温调节反应、传热理论、生理和环境温度测量以及测试实践的技术知识，以评估哪些偏离本测试方法中给出的说明是重要的。所有出发必须报告结果。

1.1 This test method covers the physiological measurement of internal body core temperature, skin temperature, thermal exposure time, heart rate response, oxygen consumption, and whole body sweat rate, to assess the effectiveness of personal cooling systems (PCS) in reducing the effects of thermal stress. 1.1.1 To increase safety during physiological testing, this dynamic test requires the use of human participants who exhibit specific health and physical fitness requirements. 1.2 This test incorporates the use of protective clothing ensembles (outer garments) used in conjunction with or worn over top of the PCS. This scope is therefore oriented to industrial rather than athletic applications. 1.2.1 The effectiveness of different PCS will be quantified with the same protective clothing ensemble. Therefore, the physiological values obtained apply only to the cooling systems, the particular protective outer garment, and the specific test conditions. 1.2.2 When a protective outer garment is not provided, this test method requires that PCS shall be tested with the standard outer garment defined within this test method. 1.2.3 The present standard does not attempt to determine important clothing characteristics, such as thermal insulation and evaporative resistance, of the PCS or of the garments worn with the PCS. Test Methods F1291 and F2370 can be referenced for these clothing measurements. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 It is the responsibility of the test laboratory to obtain the necessary and appropriate approval(s) required by their institution for conducting tests using human participants. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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 This test method can be used to quantify and compare the cooling provided by different personal cooling systems (PCS) worn with a standard outer garment or with a specified protective outer garment. 4.1.1 This test method will assess the performance of PCS based on the physiological measurement of core temperature, mean skin temperature, heart rate, exposure time, oxygen consumption, and whole body sweat rate. 4.2 Evaluating the effectiveness of PCS is an extremely complicated endeavor that involves many factors related to thermal exchange between the PCS, the environment, and the participant. It would not be practical in a test method of this scope to establish details sufficient to cover all contingencies. Therefore, a valid physiological method of measuring core temperature, along with other variables of thermal strain, provides an acceptable means of classifying the performance of PCS. This test method will also measure the amount of time the PCS maintains core temperature within safe limits during a specified condition of thermal stress. 4.3 Departures from the instructions in this test method may lead to significantly different test results. Technical knowledge concerning thermoregulatory responses, the theory of heat transfer, physiological and environmental temperature measurement, and testing practices is needed to evaluate which departures from the instructions given in this test method are significant. All departures must be reported with the results.
