Full title and description
GOST 4333-2021 — A Russian national standard that sets requirements for the characteristics, terminology and classification of polyvinyl chloride (PVC) and unplasticized polyvinyl chloride (uPVC) products used in building and construction, including pipes, fittings and profiles. The standard updates or consolidates rules for designation, marking, technical specifications and quality assessment of PVC-based construction materials to align with contemporary production and testing practices.
Abstract
This standard defines terms, classification, basic technical requirements and test methods relevant to polyvinyl chloride materials and common PVC products in construction applications. It covers parameters such as mechanical properties, dimensional tolerances, chemical resistance, methods of sampling and quality control, and marking and documentation requirements. The document is intended to ensure consistency, safety and interchangeability of PVC products in construction and plumbing systems.

Scope
GOST 4333-2021 applies to PVC and related unplasticized PVC products intended for use in building and construction, including but not limited to pressure and non-pressure pipes, fittings, profiles and associated components. The standard specifies terminology, classification by type and intended application, principal technical requirements, sampling procedures, testing methods and marking/packaging rules to be used by manufacturers, testing laboratories and regulatory bodies.
Key topics and requirements
- Definitions and classification of PVC products (by composition, plasticized vs unplasticized, application categories)
- Requirements for mechanical properties (tensile strength, impact resistance, elongation, stiffness)
- Dimensional tolerances and geometric parameters for pipes, fittings and profiles
- Chemical resistance and ageing behavior under specified environmental conditions
- Sampling procedures and conformity assessment methods
- Test methods for physical and mechanical performance, including standard test temperatures and apparatus
- Requirements for marking, labeling, technical documentation and packaging
- Safety and compliance criteria for use in potable water, drainage and ventilation systems where applicable
Typical use and users
Manufacturers of PVC and uPVC pipes, fittings and profiles; testing and certification laboratories; construction companies and installers of plumbing, drainage and ventilation systems; procurement specialists and regulatory inspectors who verify compliance with national material standards; and designers specifying materials for building projects within jurisdictions recognizing GOST standards.
