Section 11 Service Instructions
91
If the source has to be renewed, you have to specify the manufac-
turing number of the original source in your new order. This manu-
facturing number consists of three groups of digits, for example:
1234 - 11 - 97
The first group is a consecutive number, the second group identi-
fies the month (here: November) and the third the year the source
was manufactured (here: 1997). It is included on the identity plate
of the shielding and also on the leak test certificate that comes
with every source.
