Model L76C-UF, Configuration with Bend, Open End Configuration, is designed and tested according to EN ISO 16852:2016, except for: 1. The piping on the unprotected side, consisted of ignition source, “A” ft of straight pipe, one 90 degree bend, “B” ft of straight pipe, then the arrester.

2. The short time burn test was conducted at atmospheric pressure, for a time period extending past 1 minute. *No additional bends or restrictions are allowed. Bends and flow restrictions can cause additional turbulence, which can increase the intensity of the flame propagation; potentially compromising the performance of the flame arrestor. **See below configuration with bend diagram
