Determination of PMV and PPD Indices for Moderate Thermal Environments

Occupational hygiene measurements are the measurements that must be carried out by Environmental Laboratories authorized by İSGÜM with the methods determined by İSGÜM. As one of these measurements, "Determination of PMV and PPD Indices for Moderate Thermal Environments" can be considered.

Determination of PMV and PPD Indices for Medium Thermal Environments is carried out within the scope of TS EN ISO 7730 and TS EN 7243 standards. It is also emphasized that the TS EN 7243 standard should be used in the evaluation of Ambient Temperature within the scope of the “Regulation on Health and Safety Measures to be Taken in Workplace Buildings and Attachments”.

Within the scope of the measurements to be carried out according to the TS EN ISO 7730 standard, PMV, that is, Estimated Average Vote, and PPD, that is, Personal Dissatisfaction Percentage, obtained with a percentage ratio to the PMV value are obtained. If the PMV value is between -2 and +2 as a result of the measurements made according to the TS EN ISO 7730 standard, the environment can be considered as mild. If it is above +2 value, WGBT, ie Wet Chamber Sphere Temperature, must be measured within the scope of TS EN 7243 standard.

For these measurements to be made, an application should be made to experienced and authorized institutions. You can contact Nanolab Environmental Analysis Laboratory for "Determination of PMV and PPD Indices for Moderate Thermal Environments" in working environments.
