95 Thermal Conditioning
95 热老化测试

95.1 A polymeric material, not including wood, used as a water shield that is subjected to an operating temperature in excess of 65°C (149°F) as determined by the temperature test shall retain its original dimensions and shape after exposure for 1000 hours to a temperature in accordance with Table 95.1. The lamp used for the temperature test shall be as intended and marked on the furnishing, or, if the furnishing is not provided with a lamp replacement marking, the largest lamp wattage and size that will physically fit in the furnishing. Exposure time is able to be reduced by one-half for each increase in oven temperature of 10°C (18°F). If the sample is too large for the test oven, the sample is able to be cut to fit.
95.1 一种聚合物材料，不包括木材，用作经受操作的水屏障温度超过65°C(149°F)时，应保持其原来的温度.按表95.1温度，暴露1000小时后的尺寸和形状。用于温度测试的灯应按预定的要求，并在家具上作标记，如果家具没有提供更换灯的标记，最大的灯瓦数和尺寸是否符合实际在家具。烤箱温度每增加10°C(18°F)，曝光时间就能减少一半。如果样品对测试烤箱来说太大，可以将样品切割成合适的尺寸。

95.2 A gasket or bushing employed to comply with the requirements for wet locations shall, after conditioning for 168 hours in a circulating air oven at a temperature 20°C (36°F) above the temperature measured on the gasket or bushing during the temperature test, have a tensile strength of not less than
60 percent and an elongation of not less than 75 percent of the values determined before conditioning.
95.2 符合湿环境要求的垫圈或衬套应在安装后在循环空气烤箱中以高于温度20°C(36°F)的温度进行168小时的调节测量垫片或衬套在温度试验期间，具有不小于的抗拉强度
60%及伸长率不低于调质前测定值的75%。

Exception: Neoprene rubber is acceptable for 60°C (140°F) and silicone rubber is acceptable for 105°C (221°F) without being subjected to the test.
例外:氯丁橡胶可接受60°C(140°F)，硅橡胶可接受105°C(221华氏度)。
