Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of ...
The test field was organized into five lanes, each of which were divided into 100 cells marked with very light rope. The Fido explosives detector was used to analyze samples taken from each cell in each lane in order to determine the location of the buried mines under very low concentration calibration standards.
There is a choice between four possible detection taggant chemicals which must be added to plastic explosives under the 1991 International Civil Aviation Organization's Convention on the Marking of Plastic Explosives for the Purpose of Detection. In the United States the marker is always 2,3-dimethyl-2,3-dinitrobutane, usually called DMDNB or DMNB.
Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
The use of colorimetric test kits for explosive detection is one of the most simple methods for officers, and widely used method for the detection of explosives. Colorimetric detection of explosives involves applying a chemical reagent to an unknown material or sample and observing a color reaction. Common color reactions are known and indicate ...
In this case the part is pressurized (sometime this test is combined with a burst test, i.e. at 40 bar) with helium while sitting in a vacuum chamber. The vacuum chamber is connected to a vacuum pumping system and a leak detector. Once the vacuum has reached the mass spectrometer operating pressure, any helium leakage will be measured.

The Center's detector testing system uses custom-built cylindrical vacuum cryogenic dewars. The Center for Detectors (CfD) is located in Engineering Hall (Building 17) at the Rochester Institute of Technology. The CfD headquarters consists of 7,000 square feet of office and research laboratory space.
