This standard 11S:1989 is revised.
Guidelines for G7258199? Before the motor vehicle is allowed to run on the road in the charging area, the following provisions were made: 1) the general title was expanded from the vehicle safety inspection equipment set 2 history collection to the motor vehicle equipment verification and issuance rules.
b) /178.711798./1179. part 2 was added. This standard is the third part of a series of standards. This standard differs from GB117585-1980 in that 1: The lower smoke density value specified in the original standard is too strict, so it is changed to the stacking speed value. 1. The whole system of the underground gas system continues to require the full range of production safety inspection methods to carry out various inspections during use. This standard is the first part of the GB1173 EMU safety equipment verification and inspection technical regulations: Part 1 is the same as GB1.-1 version of the automobile air conditioning test and inspection Technical requirements for the following parts: Part 2 (1798.2-20): Test method for rolling mill equipment: Part 3 (ie GB11795.32301): Light oil vehicle exhaust gas analysis and emission control technology Part 4 (ie / 117.12: Simple speedometer test conditions: Part 5 (ie GB11.5-21: Reduced speed meter according to the requirements of the technical system: Part 1 (unit GBT1760) Symmetrical front light memory test instrument verification Technical conditions: Part 7 (GB/T11795.7-2001): Technical requirements for the inspection and verification of axles (wheels); Part 8 (GB/T11795.7-2001): Technical requirements for the inspection and verification of trailer wheels; Part 1 (GB/11788.S-220): 1) Technical requirements for the inspection and verification of parallel-pole brake test benches. The requirements of this standard are as follows:
This standard is based on the date of this standard and is in accordance with the G311795.51S. standard.

The smoke meter should be disconnected from the power grid, and the power switch of the smoke meter should be placed in the heat flux position. The power phase line terminal of the power supply head of the smoke meter and the protection button should be measured with an insulated resistance meter. It should be cold-closed, as specified in the 4th paragraph. 4.5 Starting point calibration
After the smoke meter is preheated, the smoke meter indication will indicate 4% of the guaranteed value. The indication at this time should be recorded in the starting indication range (standard indication time A), and the indication should be recorded in Table A1 for continuous operation. The zero point filter stop should be calculated in Table A1. It should comply with the provisions of .4,

4.6 Verification of indication error
Use a standard smoke density card with a diameter of about 5 to calibrate the smoke meter. Adjust the needle so that the smoke meter indication is consistent with the value on the standard smoke density card. The instrument is measured under the conditions of two standard sheets of paper. The nominal value of the attached smoke density card and the corresponding smoke meter indication are recorded in Table A1. (2) Calculate the corresponding indication error and fill in Table A1. S.
