introduction
This procedure is JJF1002 "national verification procedures write rules", JJF1001 "universal metering and fixed term
Justice ", JJF1009" capacity metering Terms and Definitions ", JJF1059" Evaluation and Expression of Uncertainty in Measurement "as the basis and reference
Road and rail tankers exam International Organization of Legal Metrology (OIML) International Recommendation R80-1 "has a level measurement
Part 1. metrological and technical requirements, "the English version (Roadandrailtankerswithlevelgauging, Part 1.
MetrologicalandTechnicalRequirements), adopted some of these metrological and technical requirements, test side
France and other content, combined with the actual situation of China's railway liquefied gas tanker metrology, and for JJG 184-1993 "liquefaction
Railway Tank Car Volume of gas "has been revised. Compared with JJG 184-1993 version, in addition to editorial changes of this Regulation, the
The main technical changes are as follows.
--- Increased introduction, describes the basis for the revised procedures, the use of international recommendations, replaced the previous procedures
Release conditions;
--- According to the definition of procedures JJF1001 scope has been modified (see 1);
--- Increasing the reference document, the contents of references is an essential part of the procedure (see 2);
--- Increased terms of national regulations involved did not provide a definition of the term is given (see 3);
--- Through performance tests and measurement uncertainty evaluation, verification, railways liquefied gas Tank volume 70%
The above test results of the expanded uncertainty identified as. 4 × 10-3, k = 2 (geometric measurement); 2 × 10-3, k = 2 (capacity
Comparative Law) (see 5);
--- The common technical requirements and measurement are not directly related to the content deleted, added and modified directly with metering
Related content (see 6);
--- Verification method increases the capacity of comparative law, a corresponding increase in test conditions, test equipment of the method, the calibrated
Cheng and other content, geometric measurements of the test methods and test equipment adjustment has been made (see 7.4);
Effectively increases the car --- "Car gauge reading corrected for measurement" test project to make the measurement operation
Level meter reading (see 7.4.3);
--- Adds new liquefied gas tanker technical parameters of the railway in 1993 after domestic production, updating old models
Technical parameters, increasing the volume table number prefix (see Appendix A);
--- According to changes in test items and test methods, increasing the test record table format (see Appendix B, C, F);
--- Increasing the temperature of the modified formula (see Appendix D), the volume of the pressure correction formula by the body to the appendix (see Appendix G);
--- The volume is calculated by the body to the appendix. Existing models have oval head, therefore dished head
Volume calculation delete content, increase elliptical head volume calculation content; increase the computational volume tank attachment (see Annex E).
--- The "filling height calculation method" was changed to "quasi-maximum loading height computing" to modify the calculation method (see Appendix H);
--- Modify the common shipping medium density reference table (see Appendix J);
--- According to JJF1002 requirements, modify the page format in the test certificate (see Annex K), an increase of test results
Notice page format (see Annex L).

4 Overview
Liquefied gas tanker both railway transport is also working measuring instruments. After verification, liquefied gas rail tankers
It can be used for trade settlement liquefied gas products.
Liquefied gas tanker ships from the railway tanks, undercarriage, bogie, brake, coupler and draft gear, plus handling devices, etc.
Composition, some have escort room. Tank by the head, cylinder, manholes and other components. Head is generally oval-shaped head; cylinder is
