GOST 6942.16-80 PDF

Full title and description

GOST 6942.16-80 — "Трубы чугунные канализационные и фасонные части к ним. Тройники прямые переходные низкие. Конструкция и размеры." (English: Cast iron waste pipes and fittings — Low T-branches, unequal — Construction and dimensions). The document specifies the construction, principal dimensions and designation of straight reduced low T-branch fittings for cast-iron waste (sanitary) piping.

Abstract

This is a USSR national standard (approved 1980, effective 1 Jan 1982) that defines the form, main dimensions, designation and a representative mass for straight transition low (reduced) T-branches intended for internal building drainage made from grey cast iron. The standard was one part of the GOST 6942 series for cast-iron waste pipes and fittings and has since been incorporated into the consolidated GOST 6942-98 series.

General information

• Status: Superseded / withdrawn — replaced and consolidated into GOST 6942-98 (the 1998 consolidated standard for cast-iron waste pipes and fittings).
• Publication date: Approved 4 September 1980; introduced into force 1 January 1982 (publication in Standards Publishing: 1981 edition references).
• Publisher: Approved by the State Committee for Construction of the USSR (Gosstroy USSR); published by the Standards Publishing (Издательство стандартов) / official standards bodies of the USSR.
• ICS / categories: Construction / sanitary engineering — drainage and internal sewerage fittings; falls under national classifiers for sanitary engineering and drainage systems (OKS/ОКС 91.140.x classification within sanitary and water-utility equipment).
• Edition / version: Original (1980) edition — designation ends with "-80".
• Number of pages: Short single-sheet technical drawing and specification (commercial reproductions list as 1 page / sheet for the fitting diagram and table).

Scope

The standard applies to straight reduced (unequal) low T-branch fittings manufactured for use with cast-iron sanitary (waste) pipes in internal building drainage systems. It covers the required construction form, principal dimensions, nominal designation (example: Тройник ТПРН-50/100×100 ГОСТ 6942.16-80), and indicates reference to general technical requirements, testing, marking and acceptance specified in the companion general standard for the series (GOST 6942.0-80).

Key topics and requirements

• Definition of fitting type and conventional designation (naming convention for reduced low T-branches).
• Detailed construction drawing and principal overall dimensions (socket types and tailpiece dimensions are referenced to GOST 6942.2-80 socket specifications).
• Representative mass value for a typical size (example mass listed in the standard: 4.9 kg for a shown size) and note that mass/dimensions exclude anticorrosion coating thickness.
• Reference to the series' general technical requirements: materials (grey cast iron), anti-corrosion coating requirements, marking, testing, acceptance rules and inspection methods (see GOST 6942.0-80 for sampling, dimensional tolerances and hydraulic tightness tests).
• Compatibility requirements with other items of the GOST 6942 series (ensures interchangeability with specified socket types and socket dimensions within the series).

Typical use and users

Used by manufacturers of cast-iron sanitary fittings, product design engineers, plumbing and HVAC specifiers, building contractors, quality inspectors and standards librarians. Typical applications are internal sanitary and waste-drainage systems in residential and public buildings where cast-iron pipework and fittings are specified. Designers use the standard to ensure dimensional interchangeability and correct designation for procurement and production drawings.

Related standards

Part of the GOST 6942 series for cast-iron waste pipes and fittings (other parts cover sortiment, sockets, reducers, elbows, couplings, etc.). The standard replaced earlier ГОСТ 6942.21-69 for this fitting type and was later consolidated into the unified GOST 6942-98 (1999) "Cast iron waste pipes and fittings — Specifications." Related normative documents include GOST 6942.0-80 (general technical conditions), GOST 6942.2-80 (socket types and dimensions) and the other sectional GOST 6942-x-80 standards.

FAQ

Q: What is this standard?

A: GOST 6942.16-80 is a USSR national standard that specifies the construction and principal dimensions of straight reduced (unequal) low T-branch cast-iron fittings for internal sanitary (waste) pipe systems.

Q: What does it cover?

A: It covers the geometric form, principal overall dimensions, nominal designations and a representative mass for the specified low T-branch fitting, and it refers to the series' general technical requirements (testing, marking, packaging and acceptance).

Q: Who typically uses it?

A: Manufacturers of cast-iron sanitary fittings, plumbing designers, procurement/specification teams, construction contractors and inspection bodies who need standardized dimensions and designations for interchangeability in internal drainage systems.

Q: Is it current or superseded?

A: Superseded — GOST 6942.16-80 (1980) has been superseded and consolidated into the later unified standard GOST 6942-98 (introduced 1 January 1999). For current technical and acceptance requirements users should consult GOST 6942-98 (and any later amendments).

Q: Is it part of a series?

A: Yes — it is one sectional part of the GOST 6942 family (series) covering cast-iron waste pipes and fittings; the series includes separate parts for sortiment, sockets, reducers, elbows, couplings and general technical conditions. The 1998 consolidated standard GOST 6942-98 replaces the sectional 1980-series documents.

Q: What are the key keywords?

A: Cast iron, waste pipes, sanitary fittings, reduced T-branch, low tee, construction and dimensions, GOST 6942, internal drainage, socket dimensions.
