1.1 本规程为在实验室评估包装系统承受一系列气候应力的能力提供了统一的基础，这些应力是包装系统在全球分销过程中可能暴露的，并且仍能提供产品保护，使其免受损坏或更改。 1.2 本规程设计为在测试单包裹包装系统的隔夜或两天交付系统之前进行调节，或作为包装系统气候应力的独立测试。 注1: 实践 F2825 气候应激或调节是短期的。在实际使用的气候条件下，纤维板容器预计不会接近平衡含水量 F2825 . 因此，实践 F2825 除一到两天的单件包裹交付外，不应将调节用于配送环境，因为它可能会为纤维板容器提供不准确或误导性的测试结果。 1.3 本规程不包括冷藏、冷冻食品储存或低温储存条件。 这一做法只涵盖世界各地遇到的气候环境。 1.4 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。 1.5 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 本规程提供了一种利用实际配送中出现的气候条件调节包装系统的方法。建议的暴露水平基于有关运输、搬运和储存环境的可用信息、当前行业惯例和已发表的研究。 它们不是绝对的极端，而是在世界寒冷和炎热气候中记录的每日平均值。

1.1 This practice provides a uniform basis for evaluating, in a laboratory, the ability of a packaging system to withstand a range of climatic stresses that a packaging system may be exposed to during distribution throughout the world and still provide the product protection from damage or alteration. 1.2 This practice is designed as conditioning prior to testing for overnight or two-day delivery systems of a single parcel packaging system or as a standalone test for climatic stressing of packaging systems. Note 1: Practice F2825 climatic stressing or conditioning is short term in duration. Fiberboard containers are not expected to approach equilibrium moisture content at the climatic conditions used in Practice F2825 . Therefore, Practice F2825 conditioning should not be used for distribution environments other than one- to two-day single parcel delivery as it may provide inaccurate or misleading test results for the fiberboard containers. 1.3 This practice does not cover refrigerated, frozen food storage, or cryogenic storage conditions. Only the climatic environments encountered in various regions of the world are covered by this practice. 1.4 The values stated in SI units are to be regarded as 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 This practice provides a method for conditioning packaging systems using climatic conditions that occur in actual distribution. The recommended exposure levels are based on available information on shipping, handling and storage environments, current industry practices, and published studies. They are not absolute extremes, but recorded daily averages in cold and hot climates of the world.
