Energy Institute Guidelines for the management of safety critical elements 2007
8.1 OVERVIEW OF VERIFICATION
This section provides an overview of verification and description of how verification should be approached during the various stages of the asset’s life.
8.1.1
Elements of a verification scheme
A verification scheme must address the following (see
OSCR (2005) Schedule 7):
1. The principles to be used in selecting persons to perform functions under the scheme and keep it under review (i.e. the ICP).
2. Arrangements for communicating necessary information to persons performing functions under the scheme and reviewing it. The nature and frequency of examination and testing. Arrangements for reviewing and revising the scheme. Arrangements for record keeping for examinations and tests carried out, results and findings,
recommended actions and closeout of recommended actions. Arrangements for communicating 5. to the appropriate level in the duty holder’s organisation.
8.1.2
Responsibilities of the ICP
The ICP is required to review and comment on the list of SCEs and ensure himself that Performance Standards are appropriate any reservation raised by the ICP
should be recorded. The verification scheme maybe drawn up by either the duty holder (or an appointee acting on its behalf, or the duty holder in conjunction with the ICP. If it is not drawn up by the ICP, then the ICP must review and comment on the scheme and a record of that review
(including any comments or reservations as a result of unresolved issues arising) should be retained as part of the scheme records.
The ICP is responsible for carrying out the verification activities detailed in the verification scheme. The duty holder is responsible for ensuring that the ICP is provided with all access necessary and information required to carryout the verification activities.
8.1.3
Verification activities
Verification activities are those carried out by the ICP
and are intended to either directly establish the suitability of the SCE, or to establish that appropriate assurance activities have been undertaken (e.g. the witnessing of emergency shutdown system function tests).
Both assurance and verification activities should be defined in the same written scheme of examination, but only an ICP can carryout verification activities.

The verification scheme should provide a clear indication of the nature and frequency of the verification activity that the ICP is expected to carryout. When assurance and maintenance work is carried out sufficient information should be recorded to show that the SCE remains in good repair and condition. This is particularly important where availability and reliability performance standards require to be demonstrable.
