Test of pollutant exhaustion in construction materials, furniture, automobile elements, etc.
The Ministry of Environment finalized and announced the "Indoor Air Quality Control Act for Multi-use Facilities", which was enacted on May 30, 2004. Since the Ministry of Environment stipulates indoor air quality standards for multi-use facilities and new apartment buildings and pollutants emitted from building materials, indoor air quality management and measurement of pollutants emitted from building materials are essential. KTR, an internationally recognized testing organization, has been recognized by domestic and foreign agencies for its excellent human resources, atmospheric environment measurement vehicles and the latest measuring instruments. It is necessary to confirm the compliance with the environmental safety management standards for children's activity space according to the Environmental Health Law that measures the emission amount of building materials and automobile parts and pollutant measurement for indoor air quality. We are registered and approved by the Ministry of Environment as a verification inspection agency and can test in the children's activity space.

Odor pollutants
- "Odor" refers to the smell of hydrogen sulfide, mercaptans, amines, or other irritating gaseous substances that stimulate the smell of the human body, causing discomfort and disgust.
- "Odor emission facilities" refer to facilities, machinery, and equipments that cause odors.
- The Minister of Environment determines it in consultation with the head of the relevant central administrative agency, and declare the ordinance.
- "Complex odor" refers to the smell of two or more odorous substances acting together to stimulate a person's sense of smell, causing discomfort and disgust.
- "Specified odor substance" is a substance that causes odor and is determined according to the ordinance of the Ministry of Environment. The measurement of odor is intended to determine if the emission limit is exceeded. At the outlet and site boundary, it is a principle to measure the odor by the air dilution sensory method. If it is necessary to check whether or not odorous substances are emitted, it is necessary to measure the odorous substances specified by the instrument analysis by the instrumental analysis method.
