Technical differences and|| tt|| Sichuan standard 1H/16D19%2 and its non-effective 1501817, 1985. In this standard, there is no difference in applicability between the reference standard GB/T35631994 and the non-standard 180/1>%1452:199:. The main technical requirements of the two are different, but the official version has the same rate. The main technical differences are as follows! The boost rate of GB/T5563-1914 is determined according to the explosion pressure. The boost rate of ≤:12MP is 0.075MPa/-0.75MIn/s, and the boost rate of 14.MPa~4UMPa is 0.075MPa/-0.75MIn/s. The opening pressure of 0.35MPa/3~1.175M1/240MF adopts a larger fixed force, at 120. The final output of the right station is based on the individual pressure increase rate, which is negotiated separately. The pressure rate of 13[)14h2-1994 is determined according to the nominal internal pressure, and the nominal internal pressure is 1.50 g~M. The maximum pressure of the nominal internal pressure is 1U g~M. The internal diameter of the car is 250 g--240. The main force is reached within the main body of the public. The main body is the internal diameter of the car. The other treatment is negotiated by the standard H/19 method. The standard 5045721B of B is the main body of the low temperature network. The latter is 24h using the standard GT55671 994 zero-effect color uses 1/117233:1990. Compared with the above 1507233:1951, all technical brackets are the same, and the format of the dangerous writing is slightly different. The standard GE/T5681S94 non-equivalent standard [3/15803, 1991. Compared with the stock capital TS0603.1994, the main changes involved in this part are: (1) The sample length of CB/T3588-1094 is: the nominal internal lightness 55 is 0.5R+2. The public belt internal diameter or 25 is +24; 1803:1944's length is, the public required internal size>23 is 0.5xr+0 nominal internal lightness!
