Abstract
The utility model discloses a standard sample for ROHS (Restriction of Hazardous Substances) detection. The standard sample comprises a sample box and six standard samples placed in the sample box, wherein the sample box comprises a box cover and a bottom box, accommodating grooves are formed in the bottom box, the sections of the accommodating grooves are circular, and the accommodating grooves have the diameter of 3.5-4 cm and the depth of 3-5 mm; and the six standard samples are placed in the accommodating grooves, are cylindrical and have the diameter of 3 cm and the thickness of 3 mm. Compared with the prior art that the number of ROHS standard samples is small and the quantity value range is narrow, the standard sample has the characteristics that the quantity value range of target elements is wide and the number of samples is big, the sample access is convenient, and the accuracy, quantity value uniformity and stability of ROHS detection are improved.
Description
Technical field
The utility model relates to a kind of standard model, is specifically related to a kind of ROHS detection standard model.
Background technology
Along with the enforcement of the ROHS of European Union instruction, various Electronics Factories need the strict content of controlling the objectionable impuritiess such as cadmium, mercury, PBBs, PBDEs, sexavalent chrome, lead in product.That X-ray fluorescence spectra (XPF) method is better than having is with high accuracy, speed fast, the concentration range of analytical element is wide, sample pre-treatments simple and the advantage such as Non-Destructive Testing and being widely used in during ROHS analyzes.Yet, in the analytical test process, impact due to factors such as the precision that is subject to matrix effect, physical parameter, stability of instrument, the accuracy of XPF quantitative analysis of non-sampler method is desirable not enough, must use the relatively method take standard model as the basis could obtain accurately, analyze reliably data.
Be to guarantee the accuracy that XPF measures, the researchist attaches great importance to the development work of X-fluorescence spectrometer standard model, European Union and Japan some X-fluorescence spectrometers manufacturer as far back as 2005 just to begin research and the preparation work of X-fluorescence optical spectrometer sample.European Union has developed a series of standard substances for ROHS instruction, particle shape, the SUMITOMO CHEMICAL chemistry has also been developed some samples in addition, these samples are broadly divided into plastic cement and the large class of metal alloy two, these samples adopt wave length type X-fluorescence spectrometer to test definite value to it mostly, be subjected to the restriction of the factor of instrument own, the test result accuracy is not high, and the magnitude tracing problem does not solve yet.These samples are that whether deviation is excessive for the testing instruments typical curve, its calibration value narrow range, value is not traced to the source, and need to trace to the source to national standard with standard model as calibrating, it is the foundation that the instrument overall performance is judged, the series of standards sample of contained harmful substances from 0ppm to 5000ppm, and the homogeneity of standard model, stability all to reach certain requirement, so it is improper that these samples are used as the standard model of calibrating use.China is also carrying out certain work aspect the research of X-fluorescence spectrometer standard model in recent years, China National Measuring Science Research Inst. has prepared two kinds of similar standard models, and a kind of base material is polypropylene, and three samples are arranged, the value scope is (0～1000) ppm, there is no the value of bromo element; Also a kind of base material is ABS resin, and five samples are arranged, and the value scope is (0～1100) ppm, yet these standard model ubiquity sample sizes are few, and the problems such as value narrow range can not satisfy the needs that ROHS detects fully.
The utility model content
The purpose of this utility model is to overcome the deficiency of existing product, provides that a kind of sample size is many, the value scope is wide, can satisfy the standard model that ROHS detects use.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of ROHS detects and uses standard model, comprises sample box and is positioned over the interior standard model of sample box, and described sample box comprises lid and end box, be provided with storage tank in box of the described end, the cross section of described storage tank is circular, and the diameter of described storage tank is 3.5-4cm, and the degree of depth is 3-5mm; Described standard model is 6, is positioned in storage tank, and described standard model is cylindrical, and its diameter is 3cm, and thickness is 3mm.
Preferably: described storage tank is 6, and described storage tank is distributed in end box in the mode of array.
Preferably: described lid and end box are by the hinge pivot joint.
With respect to existing product, standard model of the present utility model is 6, the value wide ranges of standard model, and the characteristics that sample size is many, and sample access is convenient, has promoted accuracy, value homogeneity and stability that ROHS detects.
Description of drawings
Fig. 1 shows the outside drawing of standard model described in the utility model;
Fig. 2 shows the stereographic map of standard model single in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, ROHS described in the utility model detects with standard model and comprises sample box 1 and 6 standard models 2 that are positioned in sample box, and described sample box 1 comprises lid 11 and end box 12, and described lid 11 passes through the hinge pivot joint with end box 12; Be provided with storage tank 13 in box of the described end 12, described storage tank 13 is 6, and its cross section is circular, and described storage tank 13 is distributed in end box 12 in the mode of array; The diameter of described storage tank 13 is 3.5-4cm, and the degree of depth is 3-5mm; Described standard model 2 is 6, and described standard model 2 is cylindrical, and its diameter is 3cm, and thickness is 3mm, is positioned over correspondingly in storage tank 13.
the object element Cd that all contains base material PE and equally distributed variable concentrations in each standard model 2, Cr, Hg, Pb and Br, wherein, the concentration of described object element Cd is 0～260ppm, the concentration of described object element Cr is 0～2000ppm, the concentration of described object element Hg is 0～1200ppm, the concentration of described object element Pb is 0～1300ppm, the concentration of described object element Br is 0～5680ppm, described object element distributes by certain concentration gradient in standard model 2, and the increase along with object element concentration in standard model 2, the appearance color of standard model 2 deepens.
Being only the utility model preferred embodiment in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
