Reviewing and optimising MPS certification standards
All MPS standards are reviewed at least once every five years and, if necessary, updated through a recurring cycle.

Revision of a standard
The process starts with identifying the required and desired changes. This is based on continuous new insights from MPS, such as an adjusted product strategy, applicable exemptions, input from different stakeholders, or market developments that lead to an improvement of the standard. The input from these various insights may result in a revision.

New version
When the general requirements and criteria change and this leads to the development of a new draft version, this draft is submitted to stakeholders through a public consultation. All users are informed about this consultation so that they have the opportunity to familiarise themselves with the changes and provide feedback. A minimum period of sixty days applies. The feedback is assessed by MPS and may then be incorporated into the new version.

After revision, the new version of the standard is submitted for approval to the Council of Experts MPS. The MPS Board ratifies this decision. The new version of the standard is published on the MPS website and communicated to relevant stakeholders.

Additional decisions
In between revisions, additional decisions regarding the general requirements and criteria can be taken to improve an MPS standard. Once a draft additional decision has been drawn up, it is submitted to the Council of Experts MPS and, after any comments have been processed, ratified and published. An additional decision enters into force immediately as a supplement to the respective standard and can be found as a separate addendum per standard. When a new version is introduced, these additional decisions are incorporated into the standard.
