ISO 9117
EN 29117
目的和应用
这种仪器按照ISO 9117和EN 29117 标准用于测试油漆，清漆和其它涂层的干燥程度。
测试原理
有尼龙纤维的冲头加载一定重量降落在涂层表面若干时间，然后转向90度。对涂层得影响可在提起冲头后检查出来。
设计和功能
这种检测仪器由一个试样台和一个用于引导垂直加载的支架组成。
一个测试冲头通过一个球窝连接器（一共重1500克）连接到加载重物上。一块橡皮薄片（硬度50 IRHD,符合ISO48标准）粘在测试头的前端，而且一张单股尼龙纤维（直径0.12mm,尺寸100＊100mm）通过O形环固定连接在测试头上。每次测试前都需要把测试头上的尼龙纤维更换一块的。
测试仪器在使用前必须调好水平，因此随即提供一个水平仪，把它放在试样台上就可通过可调脚调节仪器至水平。
在一定的干燥时间后，测试头降低放在试件上，尼龙纤维会压在测试表面。在10秒后将测试头转90度，过2秒后再提起。如果在测试表面观测不到印记或破坏，则已达干燥。否则必须在一个适合时间后重复测试过程(请参考标准)

This current-voltage tester works by sampling various currentversus voltage combinations of the photovoltaic cell with a variable impedance load. Theperformance of the photovoltaic cell is determined by measuring this output I-V relationshipwhile it is being illuminated by light. This relationship is typically called an "I-V curve" ａnd canbe obtained by exposing the photovoltaic cell to a constant level of light while varying anexternal impedance load such that its current-voltage values change. Since multiple I-V datapoints are required to create an I-V curve, an external trigger function model is available foruse with pulse solar simulators. This allows the tester to create multiple sequential pulses（typically 10-100 points selectable） to complete the IV curve measurements. Universal input100-240VAC, 50/60Hz. Software ａnd GPIB Board is included. An external computer （soldseparately） such as the PC computer controller is required to control this current-voltagemeasurement system.Purpose of Current Vs Voltage Measurement TestA solar cell may be operated over a wide range of voltage ａnd current combinations, but thereis generally an optimum combination for maximum energy collection efficiency. By varying anexternal load resistance from zero to infinity, the optimum I-V combination where the solar celldelivers the most power can be found.Current ａnd Voltage Measurement RangeThe standard I-V Test system can measure electrical power from photovoltaic cells up to 20W.The voltage envelope is limited to 200V ａnd the current is limited to 1A. A higher powered60W version is available where the voltage is limited to 60V ａnd the current is limited to 3A.For higher loads, shunts to measure a portion of the current can be used. In general, thelimitation of the standard model is the 1A current limit. If your solar cell can generate morecurrent than 1A, then we recommend upgrading to the 60W model.Voltage Scaling FactorAlthough the maximum voltage of the base unit is 200V, the software can rescale its scanningrange to 2V, 10V, 20V or 200V. Once the scale is selected, the maximum number of I-Vmeasurement points that can be taken in that selected range is 100 points.Current Density - Voltage （J-V） MeasurementsThe software currently only measures I-V characteristics ａnd JSc （mA/cm2）, but other J-V上海市闵行区莘朱路903号（甲）厂区,201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊睿科学仪器有限公司values can be derrived as J=I/area. The software outputs the I-V characteristics in an ASCIIfile which can then be read to derrive current density values.SoftwareSoftware is written in Labview, but a Labview Runtime engine allows it to run on Windows XPwithout the Labview development toolkit.System NotesThe I-V Measurement System sweeps the IV curve with an automatically adjustable resistiveload ａnd records multiple I-V data points along the way. The voltage ａnd current ranges aresoftware selectable ａnd so is the number of points taken, from 10-100 points depending onthe time length of the test allowable. The I-V data point values are then recorded ａnd plottedon a computer display ａnd saved in an ASCII text file. The points are selected by voltage,hence the voltage readings are evenly spaced.I-V Measurement BasicsFill Factor: Fill factor refers to the "squareness" of the I-V curve. It describes how closelymatched the voltage is at its maximum power point ａnd the current is also at its maximumpower point. The higher the fill factor match, the more square the I-V curve.Conversion Efficiency: The conversion efficiency of a solar cell is the percentage of lightenergy that gets converted to electrical power.References:The U.S. Department of Energy maintains a good website on how to use I-V measurementsystems in solar cell testing.

This current-voltage tester works by sampling various currentversus voltage combinations of the photovoltaic cell with a variable impedance load. Theperformance of the photovoltaic cell is determined by measuring this output I-V relationshipwhile it is being illuminated by light. This relationship is typically called an "I-V curve" ａnd canbe obtained by exposing the photovoltaic cell to a constant level of light while varying anexternal impedance load such that its current-voltage values change. Since multiple I-V datapoints are required to create an I-V curve, an external trigger function model is available foruse with pulse solar simulators. This allows the tester to create multiple sequential pulses（typically 10-100 points selectable） to complete the IV curve measurements. Universal input100-240VAC, 50/60Hz. Software ａnd GPIB Board is included. An external computer （soldseparately） such as the PC computer controller is required to control this current-voltagemeasurement system.Purpose of Current Vs Voltage Measurement TestA solar cell may be operated over a wide range of voltage ａnd current combinations, but thereis generally an optimum combination for maximum energy collection efficiency. By varying anexternal load resistance from zero to infinity, the optimum I-V combination where the solar celldelivers the most power can be found.Current ａnd Voltage Measurement RangeThe standard I-V Test system can measure electrical power from photovoltaic cells up to 20W.The voltage envelope is limited to 200V ａnd the current is limited to 1A. A higher powered60W version is available where the voltage is limited to 60V ａnd the current is limited to 3A.For higher loads, shunts to measure a portion of the current can be used. In general, thelimitation of the standard model is the 1A current limit. If your solar cell can generate morecurrent than 1A, then we recommend upgrading to the 60W model.Voltage Scaling FactorAlthough the maximum voltage of the base unit is 200V, the software can rescale its scanningrange to 2V, 10V, 20V or 200V. Once the scale is selected, the maximum number of I-Vmeasurement points that can be taken in that selected range is 100 points.Current Density - Voltage （J-V） MeasurementsThe software currently only measures I-V characteristics ａnd JSc （mA/cm2）, but other J-V上海市闵行区莘朱路903号（甲）厂区,201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊睿科学仪器有限公司values can be derrived as J=I/area. The software outputs the I-V characteristics in an ASCIIfile which can then be read to derrive current density values.SoftwareSoftware is written in Labview, but a Labview Runtime engine allows it to run on Windows XPwithout the Labview development toolkit.System NotesThe I-V Measurement System sweeps the IV curve with an automatically adjustable resistiveload ａnd records multiple I-V data points along the way. The voltage ａnd current ranges aresoftware selectable ａnd so is the number of points taken, from 10-100 points depending onthe time length of the test allowable. The I-V data point values are then recorded ａnd plottedon a computer display ａnd saved in an ASCII text file. The points are selected by voltage,hence the voltage readings are evenly spaced.I-V Measurement BasicsFill Factor: Fill factor refers to the "squareness" of the I-V curve. It describes how closelymatched the voltage is at its maximum power point ａnd the current is also at its maximumpower point. The higher the fill factor match, the more square the I-V curve.Conversion Efficiency: The conversion efficiency of a solar cell is the percentage of lightenergy that gets converted to electrical power.References:The U.S. Department of Energy maintains a good website on how to use I-V measurementsystems in solar cell testing.
