1
00:00:00.000 --> 00:00:04.207
Follow the product-contact path through
the fictional vessel.

2
00:00:04.327 --> 00:00:07.223
Include the agitator, gaskets, valve seats

3
00:00:07.344 --> 00:00:10.792
and transfer connection, not only the
metal shell.

4
00:00:10.912 --> 00:00:12.912
The installation check asks

5
00:00:13.032 --> 00:00:16.894
whether the specified materials are
actually represented

6
00:00:17.014 --> 00:00:20.255
by the installed components and their
evidence.

7
00:00:20.375 --> 00:00:23.272
A certificate for the vessel body does not

8
00:00:23.392 --> 00:00:25.995
identify an elastomer fitted later.

9
00:00:26.615 --> 00:00:29.373
A certificate says material grade X, but

10
00:00:29.493 --> 00:00:32.114
which installed item does it describe?

11
00:00:32.234 --> 00:00:34.346
Use the applicable identifiers

12
00:00:34.466 --> 00:00:39.500
and controlled supplier traceability to
link the record to the component.

13
00:00:39.620 --> 00:00:43.482
The precise method depends on the
component and project.

14
00:00:43.602 --> 00:00:47.534
Do not require one universal certificate
format or assume

15
00:00:47.654 --> 00:00:51.309
every gasket has a readable individual
serial number.

16
00:00:51.429 --> 00:00:54.532
Evaluate the traceability actually
available.

17
00:00:55.152 --> 00:00:58.669
In our example, the vessel certificate is
available

18
00:00:58.789 --> 00:01:03.548
but the installed gasket lot cannot be
linked to its material record.

19
00:01:03.668 --> 00:01:05.668
Keep the gasket finding open.

20
00:01:05.788 --> 00:01:08.961
The vessel certificate does not fill that
gap.

21
00:01:09.081 --> 00:01:12.667
Obtain applicable traceability, or use an
authorized

22
00:01:12.787 --> 00:01:15.890
corrective approach followed by
verification.

23
00:01:16.010 --> 00:01:20.769
Changing a label without evidence would
only conceal the uncertainty.

24
00:01:21.389 --> 00:01:24.333
Material identity and material suitability

25
00:01:24.453 --> 00:01:26.936
are related but different questions.

26
00:01:27.056 --> 00:01:31.125
The design review should have considered
intended exposure,

27
00:01:31.245 --> 00:01:35.038
while installation evidence identifies
what was fitted.

28
00:01:35.158 --> 00:01:40.399
If an authorized substitution changes the
material, assess the compatibility

29
00:01:40.519 --> 00:01:44.243
and qualification implications through
change control.

30
00:01:44.363 --> 00:01:47.398
Do not declare cleaning effectiveness
solely

31
00:01:47.518 --> 00:01:51.173
because the installed material matches a
certificate.
