序章
氙灯试验的主要目的就是模拟物品在太阳光下的耐 老化情况,因为物品性能等方面不同,所以承受的耐 老化能力也不相同,而一些生产厂家想要迫切的知道 自己产品抗老化性能如何,所以就因此而诞生了很多 的氙灯老化条件。其他的先不多说,暂时先为大家讲 解我们公司常用的四种氙灯条件(SAE J 25272017,SAE J 2412-2015,GB/T 1865-2008,IS0 105B06:2004方法3),以及它们间的能量时间换算 方法。我们公司氙灯设备是主要通过340nm,420nm, 300-400nm这三个控制节点,控制设备运行的。

Use manufacturers’ forms for recording calibration information.APPENDIX BPROCEDURE FOR DETERMINING COLORFASTNESS TO LIGHT(AATCC BLUE WOOL LIGHTFASTNESS STANDARDS)S copeB.1B.1.1 This Appendix describes the procedure for using AATCC Blue Wool Lightfastness Standards asreference fabrics for the purpose of determining whether the xenon-arc apparatus is operatingwithin the desired range.B.1.2 Color difference values in CIELAB units are obtained by instrumentally measuring the referencefabrics before and after a specified amount of radiant exposure.B.1.3 AATCC L-2 Blue Wool Lightfastness Standards shall be exposed daily and/or an AATCC L-4Blue Wool Lightfastness Standard shall be used to monitor a continuous three day operatingcycle. AATCC L-4 Blue Wool may be used exclusively if agreed upon between contractualparties.B.2P rocedureB.2.1 I nstruments used to determine color difference for this procedure require capability for providingCIELAB color values using illuminant D-65, 10 degree observer data. If an instrument withdiffuse geometry is used, the specular component of reflectance shall be included in themeasurement. (Refer to SAE J1767, for details).B.2.2 Calibrate the instrument to be used for the color measurements to the manufacturer'srecommendations.B.2.3 Back the reference fabric to be measured with white cardboard. Condition the backed referencefabric in a standard atmosphere (relative humidity 50 RH ± 5% and temperature 22 ± 3°C) for a minimum of 2 h. Insert one layer of unexposed material of the same lightfastness standardbetween the reference fabric and cardboard backing prior to measurement.NOTE—The reference fabrics are light sensitive. Therefore, the piece used as the backing layer during measurement will need to be replaced when noticeable color change has occurred (afterapproximately 50 uses).B.2.4 Place the reference fabric against the sample port of the instrument in such a way that a smoothsurface of the face of the fabric is presented for measurement.B.2.5 After taking an initial reading in CIELAB units, rotate the reference fabric 90 degrees and take asecond reading. Average the readings and store as the standard measurement for the identified piece of reference fabric. REMOVE THE BACKING FABRIC AND PLACE IN A LIGHT TIGHTCONTAINER FOR LATER USE.NOTE—The measurement obtained in B.2.5 cannot be used for different pieces of reference fabric. E ach individual piece must be conditioned and measured prior to exposure.B.2.6 Place the cardboard backed reference fabric (single layer) in a specimen holder and secure onthe specimen rack adjacent to the Black Panel thermometer.B.2.7 Always start the exposure apparatus at the end of the dark cycle. Expose the L-2 referencefabric and/or the L-4 reference fabric as agreed upon by contractual parties.B.2.8 After the specified radiant exposure, remove the reference fabric and the white cardboardbacking and allow them to condition at (relative humidity 50 RH ± 5% and temperature 22 ± 3°C) for a minimum of 1 hour.B.2.9 Repeat the color measurements steps specified in B.2.2 through B.2.5 on the exposed referencefabric(s) and using the previously stored pre-exposed measurement, determine the Delta L*, a*, b* and E* values.B.2.10 Compare the Delta E* value determined to that specified in the AATCC chart supplied. NOTE—The supplier (AATCC) is to provide the determined values with each purchase of reference fabric as furnished to them by IFAI Transportation Division.B.2.11 If the Delta E* value does not fall within the limits specified, do not resume the test until thereason has been determined and resolved.B.2.12 As each group of test specimens completes its specified radiant exposure, record and report thecolor change information in terms of Delta E*, values of the reference fabric piece(s) used during the test period on the Exposure Control/Report Form (Figure 1 ).APPENDIX CPOLYSTYRENE LIGHTFASTNESS STANDARDSS copeC.1C.1.1 This Appendix describes a procedure for using a Polystyrene Lightfastness Standard as areference standard for assisting in determining whether the xenon-arc apparatus is operatingproperly.NOTE—The Delta B values provided with the standard are based on the J1885 test method. They do not apply to tests that use higher or lower irradiance levels or that use different filter combinationsother than the extended UV filters. Weathering instruments that monitor UV in a broadbandrather than a narrowband should apply the equivalent broadband radiant dosages in order to use the target values supplied. Note that the broadband (300 nm – 400 nm) equivalent for 0.55 Wm-2 nm-1 at 340 nm is approximately 60 Wm -2 ) .C.1.2 Color difference values in CIELAB units are obtained by instrumentally measuring the referenceplastic before and after a specified amount of radiant exposure.C.1.3 The polystyrene lightfastness standard may be exposed to a radiant dosage (kJ⋅m-2⋅nm-1 forexample), which is equivalent to a period of 2 to 7 days.C.2 ProcedureC.2.1 Instruments used to determine color difference for this procedure require a capability foroperation which includes the specular component and provides CIELAB color values usingilluminant D-65, 10 degree observer data.

6.1.1用于加湿和其他用途的水不应在暴露的试验样品上留下任何沉积物或污迹。

所用水中固体颗粒含量不应超过1ppm,二氧化硅含量不超过0.2ppm ,二氧化硅含量的测定应参照ASTM D 859 或ASTM D 4517 。

如组合使用去离子法和反渗透法处理能够得到所要求纯度的水。

6.1.2如果适用的话,应先关闭设备上的所有喷水装置,以防止对试验样品的意外喷淋。

6.1.3如附录D,表D1及图D1说明的,安装氙弧灯管,并且带有可以提供光谱能量分布的扩展紫外线过滤器。

6.1.4设备制造商应对试验设备的认可,及由不同的OEM厂家所要求的光谱能量分布负责。

所认可的聚苯乙烯及其它的由OEM提供的作为控制的原材料的使用将决定设备的认可。

设备制造商应提供一些必要的数据来证明各种不同型号设备之间的试验结果和本标准的一致性,最基本的数据应包括(1)250nm~800nm 之间的相关光谱能量分布数值;(2)目前认可的聚苯乙烯标准参照材料的重复性与再现性数据。

6.1.5根据表1参数对试验设备进行交替循环地操作。

另外,如果试验双方同意,可以采用比较高或比较低的辐照度。

但是对于聚苯乙烯参照材料的无效的数值,已经在附录B中列出。

注2 :如果试验双方同意,循环周期可另行约定。

例如,如果辐射度值有别于默认值,则要进行说明指出。

7.试验步骤7.1准备样品,使其能安装于试验设备所用的试样夹中,并按ASTM G 147 中的要求对试验样品进行状态调节和处置。

7.2试验样品尺寸必须符合所认可试样夹的尺寸,超出尺寸的试验样品可能不会获得正确的暴露试验结果,不规则试验样品的正确的安装方式可以从合约双方正在测试的原材料中获取。

试验样品距光源的距离是影响试验样品所受辐照度、试验样品表面温度和暴露试验结果的重要因素,应依据设备制造商的指引进行操作以使试验样品能够得到均匀的辐照。

7.3用于内饰件的纺织品进行试验时应加白纸板作为背衬。

除纺织品外的其他类型试样样品,如果尺寸小于试样夹,则应该用白纸板作为背衬。

7.4为了保持所期望的的气流,试样架上所有的空位都应用惰性、不反光材料(如白纸板等)来填满,如果平板产生明显变形则应予以更换。

7.5设定好老化装置所需达到的辐照量(如KJ.m2.nm-1@34Onm),并确保以光照周期为起点开始试验。

参考材料说明,使其适应参考材料的进度时间。

7.6对于某些设备或材料,在暴露试验过程中,需要定期变换试验样品的位置,以确保每个试验样品均获得相等的辐照量。

如果材料数据没有特别说明,试验双方应就更换试验样品方式达成一致。

注1:必须注意不要将有可能不相容的试验样品放在一起进行试验,如纺织品不应与发泡材料、塑料等一同进行试验。

注2 :试验一旦开始,每天中断试验不能超过一次。

额外的操作,如打开试验箱进行样品检查等,可能会导致试验结果出现偏差。

8评价和报告8.1试验样品试验完毕后的变色程度应该依据合约双方的约定进行评价和报告,以下的一个或多个的评价方法将会涉及到:8.1.1仪器测量法8.1.1用仪器测量试验样品在试验前和接受一定辐照量后在CIELAB色空间上的颜色值, 并计算色差,测量过程可参照附录B。

8.1.2目测评价8.1.3按照AATCC评价程序1,采用AATCC灰标对色差的色牢度的等级进行分配。

8.1.4在AATCC 评价程序1中所规定的目测条件下,对变色程度用下列术语进行定量描述:a)无变化 -- 试验样品在色调、明度、饱和度上均无变化;b)轻微变化一一对试验样品进行近距离的仔细检查,才能观察到试验样品在明度和(或)饱和度上的变化,但色调无变化;c)明显变化一一容易观察到试验样品在明度和(或)饱和度上的变化,和(或)色调变化;d)严重变化 -- 明度、饱和度和(或)色调的严重变化。

9•试验报告9.1 一份暴露控制/报告表格(图形1),表明所暴露的参考材料在CIEKLAB色差仪中的色变情况,每个提交用来认可的暴露样件都要附带这样一份报告。

如果任何一个色差的数据点超出了规定的公差(控制极限),则在空白处要写明原因,及纠正措施。

9.2暴露控制/报告表格要包括如下的附加的信息:1试验室名称2. 试验设备的型号和编号3. 控制图上所列明的试验设备操作的年,月时间。
