operation of the lever. " Failure to operate, evidence of damage, or- permanent
distortion of the operating" lever or attaching parts shall constitute failure
of this test.
4.5.10 Pressure relief "device tests. - The sample disks selected in accor-

static pressure of 3360 lb/in2 at. the inlet connection for a period of 10 minutes
without evidence of leakage through- the body or valve seats.
4.6 Inspection of packaging. Sample packages and packs, and the inspection
of the preservation-packaging, packing and marking for shipment and storage shall
