GOST R 57700.37-2021 PDF

Full title and description

GOST R 57700.37-2021 — "Computer models and simulation. Digital twins of products. General provisions". The standard establishes unified terms and general provisions for creation, application and assessment of digital models and digital twins of products, including definitions of digital product model, digital twin of the product, digital (virtual) tests and related concepts.

Abstract

This national standard of the Russian Federation defines the concept of a digital twin of a product and sets out general requirements and recommended practices for development, validation and application of digital models and digital twins for engineering products. It is intended to support design, testing (including virtual testing), production and lifecycle decisions to reduce physical prototyping and accelerate time-to-market.

General information

• Publication date: Adopted/approved in 2021; entered into force (date of introduction) 1 January 2022.
• Publisher: National standard of the Russian Federation (Rosstandart); developed by FSUE RFNC — VNIIEF in cooperation with Peter the Great St. Petersburg Polytechnic University.
• ICS / categories: OKS / ICS: 01.140.01 (mathematical and computer modelling; numerical/computational methods).
• Edition / version: First edition — 2021 (GOST R 57700.37-2021).

Scope

The standard establishes the general notion of a product digital twin and sets out general provisions and requirements for development, verification/validation, use and maintenance of digital models and digital twins. It primarily applies to engineering/manufacturing products (machinery and related items), and may serve as a basis for sector-specific standards for different industries. The standard covers both new (yet-to-be-built) products and previously designed or in-service products.

Key topics and requirements

• Unified terminology and definitions for: digital model of a product, digital twin of a product, digital (virtual) tests, digital (virtual) test bench and test polygon, model adequacy, validation and verification of models and modeling software.
• Introduction of multi-level requirements system for models and modelled results (requirements that vary by purpose and criticality of decisions supported by the model).
• Requirements and recommended practices for model adequacy assessment, validation of product models, and verification/validation (V&V) of computer modelling software; notes on certification of modelling software.
• Recommendations to integrate digital twins into design, virtual testing and lifecycle workflows to reduce physical prototypes and accelerate product development.
• Reference to classification and related documents in the GOST R 57700 series (see Related standards).

Typical use and users

Primary users include product designers and engineers, digital engineering teams, system integrators, research institutes, certification and conformity assessment bodies, regulators and technical committees, and industrial organizations applying digital twin technologies in design, testing, manufacturing and maintenance workflows. The standard is particularly relevant to manufacturers in machinery, transport and high‑technology sectors (including aerospace and defense) and to organizations formalizing model V&V practices.

Related standards

GOST R 57700.37-2021 is part of a broader national series on computer modelling and simulation (the GOST R 57700 family). Closely related documents and follow-on items include standards on classification of computer models (e.g., GOST R 57700.22), validation procedures (e.g., GOST R 57700.25) and terminology / terms for modelling processes; sectoral Preliminary National Standards (PNST) and industry-specific guidance have been developed based on this general provision standard.

Keywords
