Cost savings to manufacturers

• Warranty Costs
• Penalty Costs

Only method possible for tighter leak rate requirement

• Refrigeration lnd. 2 grams/year (10-5 mbar 1/sec)
• Fuel Systems for NAS 10-5 mbar 1/sec
• Fire Extinguishers EN standard 10-5 to 10-7 mbar 1/sec
• SF6 typical 10-6 mbar 1/sec

Safety

• For containing hazardous substances - BNFL / gas meters / hydrocarbon refrigerators

Environment

• Fuel Systems leak hydrocarbons which cause climate change
• Refrigerant emissions damage ozone layer
