This Part of the Defence Standard is a guidance document whose purpose is to inform MOD project staff on the requirements for an ISRD and how these should be formulated, and to industry on the implications if an ISRD is to be part of a contract. Consequently, it will not be appropriate to call up this Defence Standard in contracts; rather a directive based on this Part of the Standard will become part of the contract.

Manager should consider before deciding whether to include an ISRD as part of his procurement strategy. It provides guidance on the actions to be taken for ISRDs at the specification, invitation to tender (ITT) and final contract stages. Guidance is given on preparation of the demonstration directive and the conduct of the demônstration. The requirements of a demonstration will vary between equipments and between Services, and this Defence Standard provides general guidelines and direction so that common procedures can be applied wherever possible.
