我可没资格批评指正，就我这英语水平，嗨，不说也罢。看了两段就头痛了，你多包涵。 9.1 In most cases, periodic evaluation of test and control materials is necessary to determine the variation in magnitude and direction of property changes as a function of exposure time or radiant exposure. 在大多数情况下，有必要以暴晒时间或辐射暴晒量为函数对测试板和标准板的涂层状况进行周期评定。 注：样板的评定方式好像是变色和粉化两方面，原文中大小和方向我选择以状况来代替。 9.2 The time or radiant exposure necessary to produce a defined change in a material property can be used to evaluate or rank the stability of materials. This method is preferred over evaluating materials after an arbitrary exposure time or radiant exposure. 材料的稳定性评估或分级可采用使材料状况达到预期变化所对应的暴晒时间或辐射暴晒量为评判依据的方法。较之对样板在一定暴晒时间或辐射暴晒量后评判其状况的方法，上述方法更具合理性。 你翻译的都很好，就是样板是分成暴晒用的测试板和最终评估比对用的标准板，这点稍微改一下就可以了。我的翻译一向是通顺为主，准确性较差，所以还是以原文为准，千万不要受我误导。

对yzs945译文部分不同的理解 10.1.5 Type of black panel (uninsulated or insulated) used. 10.1.5 使用的黑板的类型(绝缘或非绝缘). [注：]黑板或白板是试验用的标准板，其对光辐照的反应不同。 10.1.6 If required, report irradiance measured at a single wavelength in W/(m2•nm) and radiant energy for a single wavelength in J/(m2•nm). Report irradiance measured in a broad band, such as 300-400 nm, in W/m2 with the spectral region specified. Report radiant energy measured in a broad band as J/m2 with the spectral region specified. 10.1.6 如果有要求,报告在单波长时测得的辐照度[W/(m2•nm)]以及单波长的辐射能[J/(m2•nm)]。报告在宽波段,如300~400 nm内测定指定光谱区的辐照度值(W/m2)。报告在宽波段内测定的指定光谱区的辐照量[J/m2]。 10.1.6.1 Do not report irradiance or radiant exposure unless direct measurement of irradiance was made during the exposure. 10.1.6.1 除非在曝晒过程中对辐照度进行了直接测定,否则不要报告辐照度或辐射能. 10.1.8 Light and dark-water-condensation cycle employed 10.1.8 采用光照及暗室（非光照）－水－冷凝循环方式 10.1.9 Operating black panel temperature. 10.1.9 黑板的控制温度 10.1.10 Operating relative humidity during light exposure (if measured). 10.1.10 在光照期间控制的相对湿度（如果有测量）。 10.1.11 Specimen repositioning procedure (if different from that described in 8.4). 10.1.11 样件复位程序（是否不同于8.4所描述的） [注：]因为在试验过程中，样件可能被取出来观看。 10.1.12 Results of property tests. Where retention of characteristic property is reported, calculate results according to Practice D 5870 10.1.12 性能测试结果.报告样件的特性保持,根据D5870来计算结果

redanqi翻译部分:
8．1 表1列出了几个用于非金属物质荧光紫外暴露的暴露周期。在选择使用的暴露周期时取得各相关方面的同意。如果取得了各相关方面的同意，额外的冷凝间隔和时期能被取代。
8．2如果没有特别要求用别的周期，用周期2。
8．3 执行完依G154所描述的放置和样本复位程序后，在装置上制作测试样本；
8.3.1 用空白的不锈面板填充暴露区域所有空的空间。密封样本中所有大于2mm(0.08in)的洞和不规则样本周围大于1mm(0.04in)的空穴以防水蒸气的流失。给多孔的样本缚上一个固体垫如铝用作防潮层。
8.3.2 遵照如下程序用一个平面区域在装置上复位样本，除非有迹象表明发光稳定度达到了G151无需复位的要求。如果装置中没有平面区域，应用所有相关方面都同意的程序

happyjyl翻译部分(我将继续翻译到7.10,所以除非你有更好的解释,否则从7.1-7.10这几段大家都不要翻译)--感谢涂料专业人士diamond指正.diamond同时也是红外版的版主.楼主有不懂的地方可以多向diamond请教
7.1 Apply the coating to flat (plane) panels with the substrate, method of preparation, method of application, coating system, film thickness, and method of drying consistent with the anticipated end use, or as mutually agreed upon between the producer and user.
采用与最终用途一致、或生产商与客户一致通过的底材 、预处理方法、涂敷方法、涂料体系、涂层厚度以及干燥方法,将涂料涂敷于平板.
Apply:应用.这里是"涂敷"的意思.同样的,下面的method of application翻译成"涂敷方法".
Substrate:专业词汇,"底材".
method of preparation:预处理方法
coating system:涂料体系
film thickness:涂层厚度

8.3.2.2 Unless otherwise specified, reposition specimens
vertically within each specimen holder so that each spends the
same amount of exposure time in each vertical position within
the specimen holder. Fig. 2 shows the vertical rotation sequence
for cases where there are two, three, or four specimens
in a holder.
NOTE 8—In devices without irradiance control, incident energy at the
extremes of the exposure area is often only 70 % of that at the center. This condition requires that the procedures described in 8.3 be followed to ensure uniformity of radiant exposure.
8.3.3 Repositioning Frequency—Unless otherwise specified,
the repositioning frequency shall be 10 % of the exposure
increment between evaluations.
8.4 Water Purity:
8.4.1 It is recommended that deionized water be used for
water used to produce condensation.
8.5 Identification of any control specimen used shall accompany
the report.
