Full title and description

STB DVGW G 5614‑B1 2016‑06 — Unlösbare Rohrverbindungen für metallene Gasleitungen; Pressverbinder — Beiblatt 1: Ergänzung für Pressverbinder für Rohre aus unlegiertem Stahl. This document is a supplementary technical Prüfgrundlage (test / certification supplement) that provides additional requirements and amendments to the base DVGW G 5614 technical rule for press fittings used on metallic gas pipelines, specifically addressing press fittings for carbon (unalloyed) steel pipes.

Abstract

This supplement (Beiblatt B1) to DVGW G 5614 (Pressverbinder) was issued in June 2016 to extend and clarify the original Prüfgrundlage for non‑detachable (press) connections in metallic gas piping systems. It lists only the additions and changes that apply when press fittings are intended for use with unalloyed (carbon) steel pipes — for example, expanded normative references, material entries, key dimensional data (e.g., wrench‑flat heights) and bending‑stress test tables — and is only valid in conjunction with the main DVGW G 5614 document.

General information

• Publication date: June 2016 (2016‑06).
• Publisher: DVGW — Deutscher Verein des Gas‑ und Wasserfaches / Wirtschafts‑ und Verlagsgesellschaft Gas und Wasser (DVGW technical rule / Prüfgrundlage).
• ICS / categories: Pipeline components / fittings and related metal fittings (typical ICS groupings for these topics include 75.200 and 23.040.40 — pipeline components and metal fittings). (classification indicative).
• Edition / version: Beiblatt 1 (Supplement 1) to DVGW G 5614 — Edition: 2016‑06 (first edition of B1).
• Number of pages: 8 pages (supplement document length as published). Note: some distributors list a short pamphlet format (6–8 pages) depending on layout; canonical publisher listing shows 8 pages.

Scope

This Beiblatt (B1) supplements the main Prüfgrundlage DVGW G 5614 by specifying the additional or amended requirements that apply when press fittings are intended for use with unalloyed (carbon) steel piping. It is limited to the changes and additions (normative references, material specifications, dimensional tables and test parameters) and must be applied together with the full text of DVGW G 5614 (2013 edition). The supplement does not replace the main document but modifies it where noted.

Key topics and requirements

• Material identification and permitted pipe materials for press fittings when used on unalloyed (carbon) steel pipes (additions to the base material table).
• Normative references and cross‑references added or updated to reflect applicability to carbon steel.
• Dimensional clarifications (for example, additions to the table for wrench‑flat heights / key‑face heights used during pressing).
• Mechanical test requirements, including specified bending‑stress (bending load) test values or tables specific to the carbon steel pipe + press fitting combination.
• Certification / testing note: this supplement is intended to be used as part of the certification basis for press fitting systems evaluated under DVGW test procedures.

Typical use and users

Typical users are manufacturers of press‑type fittings and press‑fitting systems, testing laboratories, product certifiers and conformity assessment bodies, gas network operators, installers and engineering firms that design or qualify metallic gas distribution and service pipework. The supplement is used during type testing and certification to confirm that press fittings for carbon steel pipes meet the DVGW requirements and can be approved for gas application.

Related standards

Main related documents include the base Prüfgrundlage DVGW G 5614:2013 (Pressverbinder) which B1 amends; other related DVGW technical rules and EN standards for press fittings, metal fittings and gas installations (examples: DVGW G 5616, DVGW G 260, EN/EN‑type product standards for fittings). Users should consult the normative references listed in both the base document and Beiblatt B1 when preparing tests or certification evidence.

FAQ

Q: What is this standard?

A: It is Beiblatt 1 (Supplement 1) to the DVGW Prüfgrundlage G 5614, published in June 2016, that provides specific additions and amendments to the DVGW G 5614 technical rule for press (non‑detachable) connections when those press fittings are intended for use with unalloyed (carbon) steel pipes.

Q: What does it cover?

A: It covers the supplementary requirements only — added normative references, permitted pipe materials, dimensional clarifications (e.g., key‑face/wrench‑flat heights), and additional mechanical test data (such as bending‑stress values) specific to press fittings on carbon steel pipes. It must be applied together with the full DVGW G 5614:2013 text.

Q: Who typically uses it?

A: Manufacturers of press fittings, testing and certification bodies, gas utilities and installers who need to qualify or certify press‑fitting systems for use on carbon steel gas piping. It is also used by laboratories performing the mechanical and dimensional tests required for DVGW certification.

Q: Is it current or superseded?

A: As a supplement published in June 2016 it amends the DVGW G 5614:2013 Prüfgrundlage; users should always check with DVGW or the official document distributor for any later amendments or newer editions. The supplement itself is the published B1 edition (2016‑06) and is applied in conjunction with the base G 5614 document.

Q: Is it part of a series?

A: Yes — it is Beiblatt 1 (Supplement 1) to the DVGW G 5614 series of technical rules for press fittings; DVGW issues related technical rules and other Beiblätter for various products in the gas domain (for example other G‑series worksheets and supplements such as G 5616‑B1 for related product groups).

Q: What are the key keywords?

A: Pressverbinder; press fittings; DVGW G 5614; Beiblatt B1; carbon steel pipes; unlegierter Stahl; Prüfgrundlage; certification; press‑fit testing; bending stress; wrench‑flat height.
