1.1 本试验方法包括使用双板装置在稳态传热条件下测量露营床垫的热阻。露营床垫在保护的热板和冷板之间承受恒定的压缩力。这种方法的主要传热是一维的，垂直穿过露营垫的厚度。因此，测量的隔热值是一个可重复的比较测量。然而，需要注意的是，该值并不总是与实际绝缘性能相关，因为由于可能涉及额外的热损失（例如，边缘热损失、裸露表面热损失、压缩率变化或睡眠期间的姿势变化），现实世界的热传递可能会略有不同。 1.2 本试验方法适用于所有类型的露营床垫（例如，带或不带绝缘层的充气床垫、带反射材料的充气床垫、带或不带取芯的自充气开孔泡沫床垫、闭孔非充气泡沫床垫）。测量中应排除任何类型的辅助绝缘。辅助绝缘材料是可从床垫上移除的任何类型的材料（例如，睡袋、床垫盖）。 1.3 样品厚度不得超过中规定的热板尺寸确定的极限 7.1.2 . 1.4 单位- 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 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====== 5.1 野营床垫的热阻是绝缘性能的重要指标。本试验方法建立了在与应用相关的条件下一致测量该特性的标准。测量值可用于评估露营床垫的隔热性能，从而有助于产品结构和设计，并为消费者比较和选择床垫提供指导。

1.1 This test method covers the measurement of the thermal resistance of camping mattresses in conditions of steady-state heat transfer, using a two-plate apparatus. The camping mattress is held under constant compressive force between a guarded hot plate and a cold plate. The primary heat transfer for this method is one dimensional, vertically through the camping mattress thickness. As such this measured thermal insulation value is a repeatable comparative measurement. However, it needs to be noted that this value will not always correlate to actual insulation performance as it is feasible that real-world heat transfer will differ slightly because of additional heat losses possibly involved (for example, edge heat loss, uncovered surface heat loss, compression rate changes or posture changes during sleep). 1.2 This test method is applicable to all types of camping mattresses (for example, inflating air mattress with or without insulation, inflating air mattress with reflective materials, self-inflating open cell foam mattress with or without coring, closed cell non-inflatable foam mats). Auxiliary insulation of any type shall be excluded in the measurement. Auxiliary insulations are any type of material removable from the mattress (for example, sleeping bags, mattress covers). 1.3 The sample thickness shall not exceed the limit determined by the hot plate dimensions stated in 7.1.2 . 1.4 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 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 ====== 5.1 The thermal resistance of camping mattresses is an important indicator of insulation performance. This test method establishes criteria to measure this property consistently and in conditions relevant to the application. The measured value can be used for evaluating the thermal insulation performance of the camping mattresses, thus assisting with the product construction and design and providing guidance for consumers in comparing and selecting a mattress.
