FNiP No. 536 dated 15.12.2020 PDF

Full title and description

FNiP No. 536 dated 15.12.2020 — Federal norms and rules in the field of industrial safety: "Rules of industrial safety for the use of equipment operating under excess pressure" (Приказ Федеральной службы по экологическому, технологическому и атомному надзору от 15.12.2020 № 536). This order approves a consolidated set of safety requirements for design, manufacture, installation, operation, inspection, repair and decommissioning of pressure equipment used at hazardous production facilities.

Abstract

FNiP No. 536 establishes mandatory industrial safety requirements applicable to equipment operating under excessive (over) pressure. The document defines which types of pressure equipment are covered, sets technical and organizational requirements (design and construction rules, protective devices, testing and hydraulic/pressure tests), prescribes procedures for technical inspection, maintenance, documentation, personnel qualifications, and rules for expert review and state registration where required. It supersedes earlier pressure-equipment safety rules and serves as the primary regulatory framework for pressure-equipment safety at regulated hazardous production sites in the Russian Federation.

General information

• Status: In force (with defined validity period; currently acting as the operative set of federal norms and rules for pressure equipment in industry).
• Publication date: Signed 15 December 2020; published on official legal information portal 31 December 2020; came into force 1 January 2021.
• Publisher: Federal Service for Environmental, Technological and Nuclear Supervision (Rostechnadzor).
• ICS / categories: Industrial safety; pressure equipment; process safety; technical inspection and certification.
• Edition / version: Approved by Order No. 536 of 15.12.2020 (registered in the Ministry of Justice of the Russian Federation, registration No. 61998).
• Number of pages: Approximately 180 pages in commonly distributed editions (page counts vary between publishers/printings).

Scope

The rules apply to equipment operating under excess pressure that meet the criteria listed in the document (various types of vessels, pressure pipelines, receivers, compressors, autoclaves, gas holders, and associated assemblies). The FNiP also specifies a list of exclusions (for example certain small-capacity boilers, some shipboard vessels and other narrowly defined items are excluded) and clarifies applicability during design, construction, operation, reconstruction, repair, technical re-equipment, conservation and decommissioning of hazardous production facilities. The document is intended for use in expert reviews of industrial safety, placement, installation and operation (including commissioning, servicing, repairs, inspections and diagnostics) of pressure equipment.

Key topics and requirements

• Definitions and classification of pressure equipment by hazard criteria and parameters (pressure, volume, medium, temperature).
• Design and construction requirements: materials, strength calculations, corrosion allowance, welded joints and fabrication controls.
• Requirements for protective devices and safety systems: safety (relief) valves, burst discs, pressure and temperature monitoring, alarms and interlocks.
• Testing and commissioning: hydrostatic/pressure testing procedures, non-destructive testing, acceptance criteria and records.
• Periodic inspection, technical diagnostics and maintenance schedules; rules for repair, reconstruction and life‑extension measures.
• Documentation and record-keeping: technical passports, maintenance logs, inspection reports, certificates of conformity where applicable.
• Personnel qualification and training requirements for designers, operators, repair and inspection personnel.
• Rules for state registration, expert review of industrial safety documentation and procedures for unsafe-condition management and emergency response.
• Transitional provisions and interactions with other federal regulations and standards governing industrial safety.

Typical use and users

Primary users are industrial operators and owners of hazardous production facilities that use pressure equipment (chemical plants, refineries, power plants, food and pharmaceutical manufacturers, compressed-air systems, boiler houses, gas distribution and storage facilities). Secondary users include design and engineering organizations, independent inspection and testing bodies, certification and expert organizations, occupational safety specialists, regulatory authorities and legal/compliance advisors. The document is used when developing design documentation, conducting safety expertise, preparing operation and maintenance procedures, and during regulatory inspections.

Related standards

FNiP No. 536 replaces or consolidates requirements set out in earlier pressure‑equipment safety rules (it is published "in place of" prior documents identified in the regulatory system). It is implemented together with Federal Law No. 116‑FZ on industrial safety of hazardous production facilities and other sectoral FNiP/standards that address specific equipment types, testing methods and occupational safety practices. Amendments and draft changes to No. 536 have been prepared and published in regulatory drafting notices since issuance (users should check for the latest amending orders or drafts issued after 2020).

Keywords

FAQ

Q: What is this standard?

A: FNiP No. 536 is a set of federal norms and rules (an order of Rostechnadzor dated 15 December 2020) titled "Rules of industrial safety for the use of equipment operating under excess pressure", which prescribes mandatory safety requirements for pressure equipment at regulated hazardous production facilities.

Q: What does it cover?

A: It covers applicability criteria for pressure equipment, technical and organizational safety requirements for design, manufacture, installation, commissioning, testing, operation, inspection, repair and decommissioning, as well as requirements for personnel qualifications, documentation, registration and expert review.

Q: Who typically uses it?

A: Operators of pressure equipment at hazardous production facilities, plant and mechanical engineers, safety and compliance officers, inspection and certification bodies, designers and construction contractors, and regulatory/expert organizations use the rules in practice.

Q: Is it current or superseded?

A: The order was signed 15 December 2020, published on 31 December 2020 and entered into force 1 January 2021. Its formal period of action as published runs through 1 January 2027; users should verify whether any subsequent amendments, extensions or replacement documents have been issued after that date.

Q: Is it part of a series?

A: Yes — it is one of the federal norms and rules (FNiP / ФНП) in the industrial safety regulatory system. Other FNiP documents address related topics (for example, safety rules for lifting equipment, storage and transfer of hazardous substances, etc.); FNiP No. 536 is the dedicated FNiP for pressure equipment.

Q: What are the key keywords?

A: Pressure equipment, industrial safety, Rostechnadzor, safety valves, hydrostatic testing, inspection, maintenance, hazardous production facilities, registration, technical diagnostics.
