The emissions of restraint systems - gases, dust, and acoustics - are quantified in the industry using widely accepted methods like AKZV01, SAEJ1794, or USCAR. This report shows some background of the used analytic methods and comments the given narrow specifications based on 8 years experience of emission tests. We use pyrotechnical buckle pretensioners (PBP's) of one single lot as a probe for the evaluation of the different influences on the results. Nitrogen oxide is chosen as a key gaseous component and we demonstrate the influences of the experimental set up, humidity and pressure, on the resulting concentration. For dust analysis two methods are compared: Andersen-Impactor and Laser-Particle-Counter. The acoustic emissions are compared between car and chamber results.
