Type I — Small AppliancesCâu 84 / 240
Instead of measuring a recovery percentage, a technician chooses to evacuate a small appliance to a fixed vacuum as allowed by the rule. What vacuum level satisfies the requirement?
a.10 inches Hg vacuum
b.4 inches Hg vacuum
c.500 microns absolute
d.15 inches Hg vacuum
Giải thích
As an alternative to the 80% or 90% recovery levels, the technician may evacuate a small appliance to four inches of mercury vacuum. Reaching 4 inches Hg vacuum is treated as meeting the recovery requirement. This gives a simple, measurable target for small sealed systems.
