| Document Prefixed RIS (Rail Industry Standard) |
| A Rail Industry Standard is a non-mandatory document that a group of members of RSSB, including at least one duty holder, has requested RSSB to produce and which that group has agreed to work to. A RIS defines functional or technical provisions in circumstances when management of the railway system or subsystems does not necessitate co-operation between duty holders but where there are expected to be economic benefits from that group all doing things in the same way. They will have a number format RIS-nnnn-XXX, where RIS is the acronym for Rail Industry Standard, nnn is the four digit unique number identifier and XXX represents the three letter acronym of the approving standards committee. There are six standards committees as follows:
|
| PLT - Plant |
| RST - Rolling Stock |
| INS - Infrastructure |
| TOM - Traffic Operation and Management |
| ENE - Energy |
| CCS - Control Command and Signalling
|
| Specific responsibilities and compliance requirements are the subject of the internal procedures or contract conditions of the companies which choose to adopt the RISs, therefore any deviations should be managed by those companies. |
