2.1 Penetration Test Channels 2.1.1 Test channels for penetrations may be manifolded together for testing.

The number of penetrations manifolded together will be at the discretion

_ of the test personnel in order to perform an efficient and thorough job of leak testing..Caution must be exercised in making the test connections in the manifold assembly to eliminate leakage.

The testing ass*embly and the manifold assembly

. shall be tested for leakage before start of test.

2.2 Preliminary Testing 2.2.1 All welds that are to be covered with test channels shall be tested in accordance with a vacuum box test procedure or in accordance with a liquid pene-trant examination procedure for those welds which

. cannot be vacuum box tested because of configuration and space limitations.
