Method and device for testing a gas generator for vehicle airbags or safety belt tighteners operates a piston cylinder test unit with a gas volume flow from a gas generator set up to assess gas generator energy content

摘要

Operated as a piston cylinder device, a defined test unit (2) with a gas volume flow from a gas generator (4) is set up to move and give the most exact possible and best reproducible assessment of energy content in gas generator power (7). The test unit's movement created by the gas volume flow is recorded and used to assess the gas generator's function.
