Specific requirements shall be at the option of the contractual automotive company. The cooling plates, which are laid upon the glass plates, should apply a weight of approximately 1 kg. This is to assure a good seal for the test chamber. Numbering of the fog test chambers is given in Appendix A and Appendix B. Test operators are requested to adhere to this numbering scheme. 加热装置和冷却系统必须能保持± 0.5℃的温度精度。为防止温度过高，在温度调 节器失效的时候，温度保险开关就成了（加热）装置的重要组成部分。温度的加热 装置和冷却系统可监测并记录每次试验. 使用校准图表记录是最容易达到的，具体 要求应在合约汽车公司的选项中说明。建立在玻璃板材基础上的散热板，应能承受 大约1KG的重量。这是为了保证实验室良好的密封性。雾化实验室的编号在附录A 和附录B中已说明。每个测试操作者都要求按照这个编码安排。 4.1.1 Haake Buchler Instruments Incorporated, 53 West Century Road, Paramus, NJ 07652, (201) 265-7865 NOTE—Older models may require modifications, contact the source at the above number. 帕拉默斯世纪西道53号的Haake Buchler Instruments Incorporated ，NJ 07652, (201) 265-7865 注解—与以上编码有关系的老型号可能需要更改。 4.1.1.1 A water soluble Modified Polyvalent Aliphatic Alcohol or equivalent shall be used as the heating liquid.
