7、ladding. This test method utilizes convective hot air to achieve the exterior air temperature setpoint. The convective hot air exposure method usually provides a more severe test than infrared radiation methods because it elevates the exterior air temperature to levels that are not obtainable in rea

8、l world conditions. This method is not intended for the evaluation of individual components such as windows and doors.本检测方法为大面积外墙样板、构件和围护热循环效果评估提供了标准的实验室检测程序。此检测方法通过对流热空气以达到外部气温控制。对流热空气暴露测试方法通常会提供等比红外线辐射更严格的测试，因为该方法将外部气温提高到现实条件中所不可达到的水平上。该方法不用于独立构件如窗、门等的评估。Thermal cycling is conducted to evaluate an

The primary performance evaluations to determine the effects of thermal cycling are measured by testing air leakage (ASTM E 283) and water penetr

10、ation (ASTM E 331) before and after thermal cycling. Other tests may be used to characterize the system performance but they must be specified in the contract documents.热循环是用于评估外墙系统在受到一定量和级别的热周期后，仍能保持一定的性能特征的能力。决定热循环效果的初级性能评估是通过测试热循环之前和之后的漏气（ASTM E283）和渗水（ASTM E331）情况进行的。其他测试可能会用来鉴定系统性能的，但是此类测试需在合同文

11、件中明确标出。This test method shall not be used for condensation or dewpoint performance evaluation because of the many uncontrollable test variables associated with large wall mock-ups that prevent standardization and reproducibility. These test variables affect air flow and ambient air conditions that a

12、re necessary to reproduce standard exterior and interior air films and are difficult to control in multi-story mock-ups. It is not unusual to experience ambient air temperatures within a 3C ( 5F) range which may result in surface temperatures with a similar range. Consequently, the thermal cycling t

13、ests results will not have the accuracy or reproducibility of AAMA 1503. If condensation resistance or dewpoint performance is required, the AAMA 1503 test method shall be used.由于与大型样板相关的不可控制的测试变量很多，影响了标准化和再现性，此测试方法不得用于冷凝或露点性能评估。这些测试变量影响了再生标准外部和内部气膜所必须的气流和周边空气条件，使得很难控制多层样板。周边气温在 3C ( 5F)之间是异常的，这可能会导

14、致表面温度也会在 3C ( 5F)之间。这样AAMA热循环测试的结果就不精确或不具备再现性。如果要求阻凝或露点性能，则用AAMA1503测试方法。1.2 The primary units of measure in this document are metric. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for reference only.本问价中原度量单位是米制的。SI单位中规定的值作为标准，括号中的值仅为参考。1.3 EX

Metal and glass walls may reach equilibrium in a relatively short time. Walls containing masonry and concrete elements may r

17、equire longer periods to reach stabilized heat transfer conditions. Unless otherwise specified, the minimum number of complete thermal cycles shall be three.建筑规范专家商定异常建筑的实验室测试。金属和玻璃可能在短期内达到均衡。有砖石和混凝土的墙体可能需要更长的时间段来稳定传热条件。除非另有规定，否则完整的热循环数量最小应为三。1.5 TEMPERATURE CONTROLS AND TOLERANCES温度控制和容差The testing

18、 laboratory shall have experience in thermal testing and control as required, to provide a range of interior and exterior temperatures that can be maintained within the specified tolerance. A tolerance of 3C ( 5F) shall be acceptable.根据要求，测试实验室需具备热测试和控制经验，提供一定范围的内部和外部温度，温度能在规定的容差内保持稳定。 3C ( 5F)容差都是可

The outdoor side of the specimen shall be enclosed with an insulated chamber which shall be equipped with a means to lower and elevate the ambient temperature.

20、 The indoor side shall be equipped with a means to monitor relative humidity and temperature. The thermal cycling test shall be conducted after air infiltration and water resistance tests on, and visual examination of, the mock-up have been successfully completed. Additional air infiltration and wat

21、er resistance tests, and visual examination, shall be conducted after thermal cycling to determine if any temperature related degradation has occurred.测试方法包括将试样密封到结构测试开口。试样外侧应以隔热结构封住，隔热结构需配备能降低或提高周边温度的设备。内侧需配备监测相对湿度和温度的设备。热循环测试应在防漏气和防水测试和肉眼检查样板顺利完成之后进行。其他的防漏气渗漏和防水测试、肉眼检测应在热循环之后进行，以确定是否发生温度相关的降解现象。2.

22、2 Reusable insulated chambers may be constructed to enclose smaller mock-ups. Insulated temporary walls may be required for very large mock-ups and mock-ups of special geometry. In either event, the testing laboratory must provide temperature measurement and controls to prevent local cold or hot spo

23、ts on the exterior and interior of the mock-up.可重复使用的隔热结构可通过建造，用来包围更小的样板。可能要求临时隔热墙，以便大型样板或特殊几何形状的样板监测使用。如果是任何一种情况，测试实验室需提供问题测量和控制以便防止样板外部和内部的局部冷点或热点。3.0 SIGNIFICANCE AND USE重要性和用途3.1 This test method provides a procedure which architects and specifiers may use for evaluation of possible detrimental

24、effects resulting from thermal cycling of exterior walls, particularly as these effects may relate to air and water infiltration performance.此测试方法为建筑师和建筑规范专家提供了程序，此程序用于检测由外墙热循环导致的可能存在的有害影响，特别是与空气和水渗透性能相关的影响。3.2 Testing organizations using this test method shall have personnel knowledgeable in heat t

However it is intended to simulate, in a given period of time, the maximum temperature range the wall may experience.当前仍无与该测试方法现场性能相关的数据。但是，试图通过该测试方法模拟，在给出的一段时间内，墙体所能承受的最大温度范围。3.5 In this test method, specimens are subjected to only one of a

28、ny number of laboratory temperature cycling conditions. Therefore the results are valid only for the conditions specified.在本测试方法中，试样仅为众多实验室温度循环条件中的其中起一个，因此不同规定的条件会产生不同的试验结果。4.0 REFERENCED STANDARDS参考标准4.1 References to the standards listed below shall be to the edition indicated.
