![[-]](/dwicons/i_colpse.gif)
| Sec.1: Introduction |
Guidance note: ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
Product documents issued under previous document structures may
be called "Classification Notes" or "Guidelines".
The
latest revision of all DNV documents may be found in the publications
list in the DNV web site www.dnv.com.
| — | Sec.1 gives the general scope of the document, informative background information, definitions and references. |
| — | Sec.2 describes the certification process and the activities for each of the project phases. Furthermore, it describes the documents issued during and as a result of the certification process. The use of quality management systems is addressed here too. |
| — | Appendix A lists the instances where DNV-OS-E402 and DNV-OSS-305 requires certification. |
| — | Appendix B lists the instances where DNV-OS-E402 and DNV-OSS-305 requires attendance by DNV. |
| — | Appendix C is a list of sources to assist in obtaining reference documents. |
| — | Appendix D gives examples of certification documents. |
| — | Appendix E outlines generic project sub phases. |
| — | Appendix F is a series of key questions when selecting safety objectives. |
Guidance note: ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
For this OSS, the 'document' is a DNV certificate
or a class notation, and it is signed by DNV.
For this OSS, a 'Certificate' is a short
document (often a single page) stating compliance with specified
requirements. The results from associated verification shall be
contained in a separate (single or multiple volume) report or letter.
Guidance note: ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
In this OSS when Certification is
used it designates the overall scope of work or multiple activities
for the issue of a Certificate, whilst Verification is also used for single
activities associated with the work. This in essence means that Certification is Verification for which the deliverable
includes the issue of a Certificate.
Other (related) definitions are:
BS 4778: Part 2: Certification:
The authoritative act of documenting compliance with requirements.
EN
45011: Certification of Conformity:
Action by a third party, demonstrating that adequate confidence
is provided that a duly identified product, process or service is
in conformity with a specific standard or other normative document.
ISO
8402: 1994: Verification:
Confirmation by examination and provision of objective evidence
that specified requirements have been fulfilled.
Guidance note: ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
The usual order of preference of risk reduction measures is:
Guidance note: ---e-n-d---o-f---G-u-i-d-a-n-c-e---n-o-t-e---
The examination shall be based on information, which can be proved
true, based on facts obtained through observation, measurement,
test or other means.
