ISO 9117
EN 29117
目的和應用
這種儀器按照ISO 9117和EN 29117 標準用于測試油漆，清漆和其它涂層的干燥程度。
測試原理
有尼龍纖維的沖頭加載一定重量降落在涂層表面若干時間，然后轉向90度。對涂層得影響可在提起沖頭后檢查出來。
設計和功能
這種檢測儀器由一個試樣臺和一個用于引導垂直加載的支架組成。
一個測試沖頭通過一個球窩連接器（一共重1500克）連接到加載重物上。一塊橡皮薄片（硬度50 IRHD,符合ISO48標準）粘在測試頭的前端，而且一張單股尼龍纖維（直徑0.12mm,尺寸100＊100mm）通過O形環固定連接在測試頭上。每次測試前都需要把測試頭上的尼龍纖維更換一塊的。
測試儀器在使用前必須調好水平，因此隨即提供一個水平儀，把它放在試樣臺上就可通過可調腳調節儀器至水平。
在一定的干燥時間后，測試頭降低放在試件上，尼龍纖維會壓在測試表面。在10秒后將測試頭轉90度，過2秒后再提起。如果在測試表面觀測不到印記或破壞，則已達干燥。否則必須在一個適合時間后重復測試過程(請參考標準)

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上海市閔行區莘朱路903號（甲）廠區,201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊睿科學儀器有限公司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上海市閔行區莘朱路903號（甲）廠區,201100Tel: 021-54387376,54380568 Fax: 021-54997016 E-mail:br.sci@263.net http://www.br17.com上海泊睿科學儀器有限公司values can be derrived as J=I/area.

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.
