Full title and description

ISO 10628-1:2014 — Diagrams for the chemical and petrochemical industry — Part 1: Specification of diagrams. Defines classification, content and presentation rules for flow diagrams used in chemical and petrochemical plants, and establishes drafting rules and minimum information requirements for block diagrams, process flow diagrams (PFDs) and piping & instrumentation diagrams (P&IDs).

Abstract

Specifies how flow diagrams for the chemical and petrochemical industry should be classified, what information they must contain and how that information is to be represented. The part does not apply to electrical engineering diagrams and is intended as a collective application of ISO 15519.

Scope

Specifies classification, content and representation of flow diagrams used in chemical and petrochemical plants, and lays down drafting rules for those diagrams. Covers block diagrams, process flow diagrams (including utility flow diagrams) and P&IDs; excludes electrical engineering diagrams. ISO 10628-1 is intended to be used alongside complementary standards (for example graphical-symbol standards and general drawing/presentation standards).

Key topics and requirements

• Classification of diagram types (block diagrams, process flow diagrams, piping & instrumentation diagrams) and definition of their intended information content.
• Minimum information requirements for each diagram type (equipment identification, flow routes and directions, material denominations, flow rates, characteristic operating conditions).
• Drafting and presentation rules: sheet layout and title blocks, line and arrow conventions, lettering, recommended sheet sizes and scales, and rules for connections and auxiliary systems.
• Requirement to use consistent graphical symbols (see ISO 10628-2 and related symbol standards) and to align with ISO 15519 for diagram specification principles.
• Normative references to related ISO standards for drawing presentation, lettering, sheet sizes and units (for example ISO 128, ISO 3098, ISO 5457, ISO 7200, ISO 14617, ISO 80000).

Typical use and users

Used by process engineers, chemical/petrochemical plant designers, P&ID drafters, technical illustrators, engineering document controllers and safety/operations personnel who prepare, review or use process documentation. Employed during FEED, detail design, commissioning and operations to ensure consistent, unambiguous flow-diagram presentation and information exchange across organizations and disciplines.

Related standards

Closely linked documents include ISO 10628-2 (Graphical symbols), ISO 15519 (Specification for diagrams for the process industry), ISO 14617 (graphical symbols), and other ISO technical drawing standards (ISO 128, ISO 5457, ISO 7200, ISO 3098, ISO 80000). ISO 10628-1 and ISO 10628-2 together supersede earlier ISO 10628 editions.

FAQ

Q: What is this standard?

A: ISO 10628-1:2014 is the part of ISO 10628 that specifies the classification, content and presentation rules for flow diagrams used in the chemical and petrochemical industry.

Q: What does it cover?

A: It covers block diagrams, process flow diagrams (including utility flow diagrams) and piping & instrumentation diagrams, defining minimum information content and drafting/presentation rules; it does not cover electrical engineering diagrams.

Q: Who typically uses it?

A: Process and plant engineers, P&ID drafters, technical illustrators, document controllers, and operations/safety staff involved in preparing or using process diagrams.

Q: Is it current or superseded?

A: ISO 10628-1:2014 is the published first edition for Part 1 (published September 2014) and, together with ISO 10628-2, replaced earlier ISO 10628 editions. Users should check national/adopted versions or later ISO revisions for updates.

Q: Is it part of a series?

A: Yes — ISO 10628 consists of at least two parts: Part 1 (Specification of diagrams) and Part 2 (Graphical symbols). Part 1 is a collective application standard referencing ISO 15519 for broader diagram specification principles.

Q: What are the key keywords?

A: Process flow diagram (PFD), piping and instrumentation diagram (P&ID), block diagram, chemical industry, petrochemical, graphical symbols, drafting rules, ISO 15519.
