GOST R 57997-2017 PDF

Full title and description

ГОСТ Р 57997-2017 — "Арматурные и закладные изделия сварные, соединения сварные арматуры и закладных изделий железобетонных конструкций. Общие технические условия" (Welded reinforcing products and inserts, welded joints of reinforcement and inserts for reinforced concrete structures. General specifications).

Abstract

This national Russian standard establishes general technical requirements, dimensions, manufacturing and acceptance rules for welded reinforcing products and embedded (anchorage) parts, and for welded joints of reinforcement used in prefabricated and cast-in-place reinforced concrete structures. It sets material, welding, inspection and marking requirements and references related normative documents. The standard was approved by the Federal Agency for Technical Regulation and Metrology (Rosstandart) and introduced for use in the Russian Federation in 2018.

General information

• Status: Active / national standard in force (introduced for the first time; effective date on territory of the Russian Federation: 1 May 2018).
• Publication date: Approved by Rosstandart by order No. 1835‑ст on 24 November 2017; introduced (effective) 1 May 2018.
• Publisher: National standard of the Russian Federation (approved by the Federal Agency for Technical Regulation and Metrology — Rosstandart); published in collections/ databases and by standard publishers (e.g., Стандартинформ and commercial standards databases).
• ICS / categories: Construction materials and construction — classifiers under 91 (construction); related classifier entries include 91.190 (fittings for buildings) / 91.080 / 91.100 family (concrete/reinforced concrete structures and fittings).
• Edition / version: Original national designation: ГОСТ Р 57997-2017 (first introduction; 2017 text).
• Number of pages: Publisher/collection counts vary (commonly listed as 26–28 pages depending on formatting and vendor).

Scope

The standard applies to welded reinforcing and embedded products for reinforced concrete structures and to welded joints of reinforcing bars executed during manufacture and installation of precast and erection of monolithic reinforced concrete structures and products. It specifies requirements for products made from deformed reinforcing steel and reinforcing wire, and excludes embedded items that do not contain anchor rods made from reinforcing bars. The document is intended to harmonize technical requirements, dimensional tolerances, welding and control procedures for welded reinforcing assemblies used in building and civil construction.

Key topics and requirements

• Definitions and classification of welded reinforcing products and embedded (anchorage) parts.
• Material requirements for reinforcing bars and wire used to manufacture welded reinforcing items (references to relevant GOSTs for steel grades and wire).
• Design and dimensional requirements, manufacturing tolerances and permissible deviations for reinforcing products and welded assemblies.
• Welding types, constructions and basic technological requirements for welded joints of reinforcement and embedded parts.
• Inspection and testing methods (visual, dimensional checks, mechanical testing references, ultrasonic and other non‑destructive controls where applicable) and acceptance criteria.
• Marking, packaging, storage and documentation (manufacturer’s marking, certificates and accompanying documentation).
• Normative references and cross‑references to related GOSTs and regulatory documents used for materials, measuring tools and test methods.

Typical use and users

Typical users include structural and fabrication engineers, manufacturers of welded reinforcement cages and embedded parts, concrete product factories, construction contractors and site installers, quality control and inspection laboratories, certification bodies and regulatory authorities responsible for construction materials and prefabricated reinforced concrete elements. The standard is applied where welded reinforcement assemblies are designed, produced or accepted for use in reinforced concrete structures.

Related standards

This standard replaces or is recommended in place of earlier related documents (notably it is recommended to be used instead of ГОСТ 10922‑2012 for some topics) and references several other GOSTs, including standards on welded joint types and dimensions (e.g., ГОСТ 14098‑2014), reinforcing rolled products (ГОСТ 34028‑2016), measuring tools and testing methods (various GOSTs cited within the text). It is part of the set of standards governing reinforced concrete materials and products in Russia.

FAQ

Q: What is this standard?

A: ГОСТ Р 57997-2017 is a Russian national standard that defines general technical conditions for welded reinforcing products and embedded parts, and for welded joints of reinforcement used in reinforced concrete structures. It provides manufacturing, dimensional, welding and acceptance requirements.

Q: What does it cover?

A: It covers the classification, material and dimensional requirements, permissible deviations, welding constructions and procedures, inspection and testing methods, marking and documentation for welded reinforcement items and embedded parts used in precast and cast‑in‑place reinforced concrete work. It explicitly excludes embedded items with no anchor rods made from rebar.

Q: Who typically uses it?

A: Manufacturers of welded reinforcement cages and embedded parts, structural and site engineers, precast concrete plants, construction contractors, QA/QC laboratories and certification bodies — anyone involved in production, installation or acceptance of welded reinforcement assemblies for reinforced concrete.

Q: Is it current or superseded?

A: As published, ГОСТ Р 57997-2017 is an active national standard. It was approved by Rosstandart on 24 November 2017 (Order No. 1835‑ст) and introduced on 1 May 2018. Users should verify whether any later amendments or revisions have been issued by Rosstandart or in national databases before relying on the standard for certification or regulatory compliance.

Q: Is it part of a series?

A: It is part of the family of Russian standards related to reinforcement and reinforced concrete products; it references and complements other GOSTs (for example, ГОСТ 14098‑2014 on welded joint types and dimensions and earlier ГОСТ 10922‑2012 which it is recommended to replace in application). The standard belongs to the broader set of construction and concrete product standards under the 91 classifier.

Q: What are the key keywords?

A: Welded reinforcing products; embedded (anchorage) parts; welded joints of reinforcement; reinforcing bars; reinforcing wire; welding requirements; dimensional tolerances; inspection and testing; marking; reinforced concrete structures.
