Gas Canisters vs. Tent Waterproofing
Comparing 2 standards across 18 specifications. 18 key differences identified.
Portable camping gas canisters are certified under European standard EN 417 and US DOT-2P/2Q specifications. The international outdoor standard is the threaded Lindal B188 self-sealing valve featuring a 7/16"-28 UNEF thread (used by MSR, Jetboil, Primus, Snow Peak in 100g, 230g, and 450g sizes). The fuel mixture is typically an 80/20 or 70/30 Isobutane/Propane blend (with boiling points of -11.7 °C and -42 °C) to ensure vapor pressure in cold mountain conditions.
Tent fabric waterproofing and water resistance are measured under ISO 811 using the Hydrostatic Head (HH) test, expressed in millimeters of water column (mm HH). A fabric rated at 1,500 mm HH can support a 1.5-metre column of water before leakage occurs. Industry standards classify rainfly fabrics from 1,200–3,000 mm HH (lightweight backpacking silicone/PU nylon) to 5,000–10,000 mm HH for heavy expedition groundsheet tub floors, sealed with hot-applied polyurethane seam tape.
