TS EN 62708

TS EN 62708 is a standard for the kinds of documents used in electrical and instrumentation projects in the process industry, together with the basic content expected in those documents. It helps define what information should be separated into distinct project documents and how those document types are understood in an engineering workflow. In general technical terms, electrical and instrumentation documentation is the information backbone that supports design, installation, commissioning, operation, and maintenance.

Why document kinds are separated

Process-industry projects involve many engineering disciplines at once. Power distribution, field cabling, instrumentation loops, equipment lists, and control functions all serve different purposes and are not best handled in a single record. This standard addresses that organisational need by treating project information as a set of distinct document kinds, which improves consistency, traceability, and communication between teams.

From a general engineering perspective, this separation distinguishes design intent from implementation detail. One document may act as a master reference, another may capture wiring or I/O detail, and another may define control and instrumentation functions. That structure makes project documentation easier to read, maintain, and revise over the life of the plant.

What the standard covers

According to the scope provided, the standard covers the specific documents required for electrical and instrumentation projects in the process industry and their basic content. The emphasis is therefore on document categories and core information elements rather than on equipment performance or test procedures. It provides a common reference framework for the terminology and document structure used in electrical and instrumentation engineering.

• Classification of electrical and instrumentation project documents
• Definition of basic content elements for those documents
• Organisation of project information for process-industry use
• Support for clearer interdisciplinary engineering communication
