This procedure combined with China's national conditions, the use of the International Organization of Legal Metrology (OIML) International Recommendation R112 "with And record pressure gauge indicating the type of the elastic element, vacuum gauge, pressure - vacuum gauge (General Instrument), "part of the content. This procedure is in JJG 52-1999 "spring tube general pressure gauges, pressure vacuum gauge and vacuum gauge" and JJG 573- 2003 "diaphragm pressure gauge" two procedures on a consolidated basis, preserving effective content premise amendment. This procedure compared with JJG 52-1999, JJG 573-2003, in addition to editorial changes, the major technical changes are as follows. --- Press JJF1002-2010 requirements, increasing the content of the Preamble; --- Regulations covering the content JJG 52-1999, JJG 573-2003 two procedures for elasticity General element type pressure gauges, pressure vacuum gauge and vacuum calibration table; --- Delete the contents of the measuring range upper limit of the range; --- Improve the content of the overview; --- Refine the test conditions; --- Straighten out the order of test items and test methods; --- Added "test certificate/test results within the notice page format and" Appendix; --- Remove the gauge tolerance calculated value list. Usually the elastic element type pressure gauges, pressure vacuum gauge And vacuum meter testing procedures1 ScopeThe order applies to general formula elastic element pressure gauges, pressure vacuum gauge and vacuum gauge (hereinafter referred to as gauge) of Initial verification, use and subsequent verification check. 2.

Gauge works by using elastic sensing element (such as a spring tube) elastically deformed under pressure, The role of its shape and size of the pressure variables into a linear relationship, through a transmission mechanism amplified by the pointer in the indexing plate On indicates the pressure measured. Elastic pressure gauge sensitive element can be divided into. spring tube, bellows, diaphragm ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 52-2013_English be delivered?Answer: Upon your order, we will start to translate JJG 52-2013_English as soon as possible, and keep you informed of the progress.
