Environmental measuring instrument (7 types)
CO/HC instrument, Excess air ratio instrument, Exhaust instrument, Noise instrument, Emission instrument for dynamometer, Dynamometer, Nitrides instrument for diesel vehicle
Device Accuracy Test Method
Apparatus and Instrument Accuracy Test
Purpose
To protect the life and property of citizens by ensuring the safety of vehicles and preventing traffic accidents through the maintenance of apparatus and instrument used for testing and repair of automobiles, the most widely used mode of transportation
Test Subject
Those utilizing apparatus and instrument for testing, repairing, and/or maintaining a vehicle are required to take the following tests:
Those who build, assemble, or import such apparatuses and instruments for commercial purposes
Those who use such apparatuses and instruments
Those who intend to modify the apparatuses and instruments they currently use
Type and frequency of tests
Initial accuracy test
Upon installing newly built apparatuses and instruments or relocating them
Structural modification accuracy test
Before modifying the apparatuses and instruments they currently use
Regular accuracy test
Every 12 months following an initial test or a structural modification accuracy test
Environmental meter accuracy test
Purpose
To measure accurately the pollutants and noise from a vehicle by maintaining the precise accuracy of the meter used to measure vehicle emission and noise in order to identify and remedy any fault, to reduce daily life noise, and prevent air pollution so that citizens can live a pleasant life. TS is also designated as the official test organization by the National Institute of Environmental Research (NIER) in order to ensure consistency for the environmental meters used in Korea.
Test Subject
Those who use an apparatus/instrument for measuring or analyzing any environmental pollutant are required to take this accuracy test
Frequency
Those who use an environmental meter are required to take an initial accuracy test, followed by the second test no more than 30 days before or after the end of the period from the date of the initial test as determined and announced by the president of NIER at a designated test organization.
