JJG 117 "flat" is identical with the International Organization for Standardization (ISO ) standard ISO 8512-1 Series Tablet Cast iron plate (Surfaceplates-Part 1. Castiron) of GB/T 22095-2008 "iron plate" and repair Change the use of ISO 8512-2 Flat Rock (Surfaceplates-Part 2. Granite) of GB/T 20428-2006 "Flat Rock" as the basis for revising JJG 117-2005 version. Compared with JJG 117-2005, in addition to knitting Series modifications, mainly technical changes are as follows. --- Specification definition flat; --- To allow limited term instead of flatness flatness maximum allowable error term original statutes; --- Cancel the original procedures flat 5 accuracy levels of 00, consistent with national and international standards will be flat Board is divided into 0, Level 1, Level 2 and Level 3 four levels of accuracy; --- According to national standards, regulations and the flat working surface of the plate corresponding to the level of accuracy allowed limit; --- Expanding the number of contact points, the difference between any two positions of the contact points and support Face area ratio of the scope of application Wai, which was expanded from local Faces applied scraping iron plate to plate the whole Face, and restrictions in the new Cast iron plate made or repaired; --- Narrowed the definition of partial working face, and clearly gives the arbitrary locally flat working surface flatness allowed limit; --- Cancel the performance measurement requirements for the measurement uncertainty requirements; --- Revised to flat working surface and side surface roughness measurement method; --- Revised for flatness measurement method described in the flatness evaluation method and sample data, etc. into the appendix; --- Added Appendix A "flat working surface flatness allows the calculation of limit," so any specification plate By calculating the appropriate uniform can get flat working surface flatness allowed limit; --- Added Appendix B "Face flatness of data processing", help beginners understand the flat working surface level Measuring principle and measuring method of the surface; --- Revised the "flat working surface flatness measurement example of data processing," the original procedure in the appendix (see Appendix C), And procedures to make changes accordingly; --- Amendments to the original regulations appendix "flat working surface flatness measurements Uncertainty Evaluation" (see Appendix E), to make it more reasonable; --- Amendments to the original regulations appendix "verification certificate and test results in the notice page format" (see Appendix F), Meet the relevant provisions of the national technical norms. JJG 117-2005 of previously issued as follows. --- JJG 117-1991 --- JJG 117-1978 Tablet test procedures1 ScopeThe order applies to cast iron plate and Flat Rock (hereinafter referred to as the tablet) of the initial verification, use and subsequent verification Check. 2. References This procedure references the following documents. GB/T 20428-2006 Flat Rock GB/T 22095-2008 cast iron plate For dated references, only the dated edition applies to this procedure; undated reference documents Member, the latest edition (including any amendments) applies to this procedure.3 OverviewFlat planar reference instrument for workpiece inspection or crossed. Tablet press accuracy level is divided into 0, Level 1, Level 2 and Level 3. Usually 0, Class 1 and Class 2 flat as Inspection plate use, level 3 is used as a flat dash plate. Press material is divided into flat iron plate and Flat Rock; by structure type flat iron bars into plate, box-type, Figure 1 (a), (b); and a flange into the rock plate without flange, shown in Figure 1 (c), (d).4 metering performance requirements4.1 Face flatness 4.1.1 flat working surface flatness allowed limits specified in Table 1. Face plate in the edge region defined (see Table 1) at any point within the region if it is not higher than the outside Face Point, the flatness of the edge region may not be requested. 4.1.2 fresh or repair after scraping iron plate work surface contact between any two points and the position of the contact points The difference shall be in accordance with Table 2. Measurement of the contact points in case of dispute, the area ratio should be measured and support Face Any difference between the two units supporting the area ratio of the area, and as a final measurement result, shall be in accordance with Table 2 Provisions. Face plate at any point in the edge region of a predetermined, if it does not face up points outside the region, this Support points or support area ratio of the edge region may not be requested. 4.2 Local Face flatness 4.2.1 Face flat diagonal length ≥566mm, should be measured at any of the local workers 250mm × 250mm For surface flatness. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 117-2013_English be delivered?Answer: Upon your order, we will start to translate JJG 117-2013_English as soon as possible, and keep you informed of the progress.
