标准范围
This document defines a method for determination of off-gassing (permanent gases) and oxygen
depletion from woody as well as non-woody biomass, including densified materials such as pellets and briquettes, as well as non-densified materials such as chips. The method is also applicable for thermally treated materials, including torrefied and carbonized materials.
The emission and depletion factor and emission and depletion rate for various gas species emitted from sample within a closed test container is determined by means of gas chromatography.
The emission and depletion factor and emission and depletion rate provide guidance for ventilation
requirements to keep gas concentrations below Permissible Exposure Levels (PEL) in spaces where
workers can be exposed to the enclosed atmosphere.
