Step 6: Equipment Setup for Confined Testing - Not Required
Confined testing was done to capture total HCN from a sample.
In this case, the lid is sealed and no gasses are allowed to escape. The result is to capture the "total" HCN emitted for a sample, undiluted by the surrounding air. The HCN sensor is placed inside of the column and as it is clear, values can be seen.
The following are measured per the photo:
Heater Block Temperature - This is what will heat our plastic samples
HCN measurement of emissions
NOTE: This is not a part of the required 3D Printing test and is added here as a point of interest only.
There were over 20 hours of video and several hundred readings taken by taulman3D for the materials noted and several materials not mentioned here.
