GOST 21485-2016 PDF

Full title and description

GOST 21485-2016 — Бачки смывные и арматура к ним. Общие технические условия (Flushing cisterns with fittings. General specifications). This interstate (GOST) standard establishes technical requirements, dimensions, marking, testing and handling rules for flushing cisterns and their filling and discharge fittings used in sanitary installations of buildings and structures.

Abstract

GOST 21485-2016 specifies general technical conditions for flushing cisterns intended for flushing toilet bowls and floor bowls, together with the filling (inlet) and discharge (flush) fittings. It covers design-related basic dimensions, functional requirements, performance and type testing (including pressure and noise considerations), marking, packaging, storage and transportation. The standard replaces the earlier GOST 21485-94 and is intended for manufacturers, testing laboratories, designers and regulatory bodies involved with sanitary equipment.

Scope

The standard applies to flushing cisterns intended for flushing toilet bowls and floor bowls in sanitary units, residential and other buildings, and to the associated filling (inlet) and discharge (outlet/flush) fittings. It covers fittings designed to operate with potable water supply pressures approximately in the range 0.05 to 1.0 MPa, and sets out requirements for dimensions, materials, performance tests, marking, packaging, storage and transportation.

Key topics and requirements

• Permitted types and basic overall and connection dimensions for flush cisterns and related fittings.
• Functional performance requirements for filling (inlet) valves and discharge (flush) mechanisms, including operational reliability and sealing.
• Design and material requirements that affect durability, corrosion resistance and sanitary safety.
• Pressures of normal operation (water supply pressure range ~0.05–1.0 MPa) and related test procedures.
• Type and routine tests, including performance, leakage, endurance and noise (referenced noise test methods).
• Marking, packaging, storage and transportation rules to ensure product traceability and integrity in delivery and storage.
• Reference to normative documents and related GOSTs used for test methods and ancillary requirements.

Typical use and users

Manufacturers of sanitary porcelain and plastic cisterns and fittings, plumbing and sanitary equipment designers, product conformity and testing laboratories, building contractors and procurement/specification engineers, and regulatory bodies responsible for approval and market surveillance of sanitary fixtures use this standard to ensure consistent product quality, interchangeability and compliance with national technical requirements.

Related standards

The standard supersedes GOST 21485-94. It references and is used alongside related GOSTs for test methods and supplementary requirements (examples include standards for noise measurement of sanitary-technical fittings and methods for testing ceramic sanitary products). Relevant referenced standards include items such as GOST 27679-88 (noise testing for sanitary fittings) and standards for ceramic sanitary testing among others.
