Additive manufacturing of polymers — Environment, health and safety — Test method for the determination of particle emission rates from desktop ME printers cen:proj:75406

Scope

PROVISIONAL SCOPE [TO BE UPDATED]
This standard specifies test methods to determine particle emissions (including ultrafine particles) and
chemical substances (VOC, aldehydes) from Material Extrusion(ME) processes often used in non industrial environments such as school, homes and office spaces in an Emission Test Chamber (ETC)
under specified test conditions.

This standard comprises a preparation method in a controlled ETC of temperature, humidity, air
exchange rate, and monitoring, storage, analysis, calculation and reporting of emission rates.
This standard provides a specific process for standard operating conditions of 3D printer and test
sample to evaluate particle emission rates and chemical concentrations during the 3D printing
operation with thermoplastic materials.
