NF EN ISO/ASTM 52933, E67-402 (03/2024)

This document specifies a test method for measuring hazardous substances emitted during the operation of material extrusion type AM machines commonly used in non-industrial locations, and includes non-prescriptive suggestions for reducing them. This document specifies some of the main hazardous substances emitted from this type of machine during operation for materials commonly used today, describes additional information and the associated test method for measuring hazardous substances, and includes considerations for reducing hazardous substances and basic countermeasures. This document specifies how to measure the concentrations of hazardous substances generated in non-industrial places (schools, public places and the like) in which this type of machine is installed, and to maintain an acceptable working environment by managing field installations, machines, filaments, and products made by additive manufacturing for the reduction of hazardous substances. However, this document does not cover all gas-phase chemical emissions. Only a range of Volatile Organic Compounds (VOCs) from n-hexane to n-hexadecane, including aldehydes, are included. Considerations for reducing chemical emissions and improving the working environment are provided in Annexes A and B.
