The threshold liquid phase saturation pressure that defines Very-High-Pressure appliances is above what value at 104F?

Very-High-Pressure appliances are defined by the liquid-phase saturation pressure of the refrigerant at a reference temperature of 104°F. If that saturated-liquid pressure is above 355 psia at 104°F, the appliance is classified as Very-High-Pressure. This 355 psia threshold at 104°F is the standard line regulators use to differentiate VH equipment and assign the appropriate safety and servicing rules. The other values aren’t the recognized cutoff, since they don’t match the established 355 psia limit used at the 104°F reference point.
