GOST 21.602-2016 PDF

Full title and description

GOST 21.602-2016 — System of design documents for construction. Rules for execution of heating, ventilation and air conditioning working documentation. The standard establishes the composition, content and rules for preparing working (construction) documentation for heating, ventilation and air‑conditioning (HVAC) systems in buildings and structures of various purposes.

Abstract

GOST 21.602-2016 defines the required set of working drawings, diagrams, specifications and graphical conventions for HVAC systems within the SPDS (System of Project Documentation for Construction). It prescribes layout of plans and sections, graphical symbols to be used (in accordance with related GOSTs), rules for specification tables and lists of equipment, and the presentation of measurement and designation data necessary for the fabrication, installation and commissioning of HVAC installations.

Scope

The standard applies to preparation of working documentation for systems of heating, ventilation and air conditioning (HVAC) for buildings and structures of all types and functions. It covers the structure and content of working drawings, required diagrams and schemes, specifications of equipment and materials, marking and designation conventions, dimensioning and presentation rules on plans/sections, and requirements for notes and title blocks used in HVAC documentation within the SPDS framework. It does not set technical performance requirements for HVAC equipment themselves (those are covered by product and system standards).

Key topics and requirements

• Composition and required sheets of HVAC working documentation (plans, schematic diagrams, axonometric views, sections, schedules and specifications).
• Rules for graphic presentation of pipelines, ducts, fittings, equipment and control/instrumentation symbols (references to related GOSTs for graphical symbols).
• Designation systems and numbering for installations, pipelines, rooms and equipment; title block and drawing header conventions.
• Requirements for dimensioning, tolerances and indication of diameters/section sizes for ducts and pipes on plans and sections.
• Rules for preparation of specifications, items lists and grouping of equipment, fittings and accessories.
• Inter-references to other SPDS standards (e.g., standards for symbols, hoisting equipment, equipment specification, general SPDS principles).

Typical use and users

Primary users are HVAC design engineers, architectural and MEP designers, engineering consultants, contracting firms preparing working drawings, construction project managers, reviewers at building authorities and organizations that produce or check construction documentation in jurisdictions recognizing GOST / SPDS rules. The standard is used when preparing contract-level working documentation for installation and commissioning of HVAC systems.

Related standards

GOST 21.602-2016 is part of the SPDS (GOST 21) family and cross‑references several related documents, for example GOST 21.205 (graphical symbols for systems), GOST 21.112 (hoisting-and-conveying equipment representation), GOST 21.208 (designation of instruments and automation), GOST 21.101 and GOST 21.114 (general SPDS rules and sketch/technical documentation requirements). It replaces earlier editions of GOST 21.602 (2003/previous).

FAQ

Q: What is this standard?

A: GOST 21.602-2016 is an interstate (GOST) standard in the SPDS series that sets rules for preparing working documentation (construction drawings, schemes, specifications) specifically for heating, ventilation and air conditioning systems.

Q: What does it cover?

A: It covers the composition and graphic presentation of plans, diagrams, sections and specifications for HVAC systems; designation and numbering conventions; requirements for title blocks and lists; and normative references to graphical symbols and instrument designation standards. It does not specify the performance characteristics of HVAC equipment.

Q: Who typically uses it?

A: HVAC and MEP designers, architects, engineering consultancies, contractors producing working drawings, and regulatory/review bodies that accept SPDS-formatted documentation.

Q: Is it current or superseded?

A: As published it is current/effective. GOST 21.602-2016 replaced the earlier GOST 21.602 (2003 edition) and was approved by Rosstandart on 25 November 2016 and introduced from 1 July 2017; subsequent corrigenda or amendments (e.g., a noted поправка introduced in January 2022 in some publications) should be checked against the official registry for the latest consolidated text.

Q: Is it part of a series?

A: Yes — it is part of the GOST 21/SPDS family (System of project documentation for construction). The SPDS series includes general SPDS rules and many discipline-specific documents (drawings, specifications and symbol standards) that work together when producing construction documentation.

Q: What are the key keywords?

A: HVAC, heating, ventilation, air conditioning, working documentation, construction drawings, SPDS, graphical symbols, equipment specification.
