Full title and description

St API St 6FA-2018 rus — Russian-language edition/translation of API Spec/Std 6FA:2018, "Standard for Fire Test for Valves". This document is the fourth-edition (2018) Russian translation of the API standard that defines methods and acceptance criteria for fire testing of pressure-containing valves used in oil and gas applications.

Abstract

This standard establishes requirements for conducting a standardized fire exposure test (30-minute exposure) and for evaluating the pressure-containing performance and allowable leakage of API 6A and API 6D valves when exposed to fire. It sets pass/fail criteria, prescribes pre- and post-test inspections and reporting items, and identifies exclusions (for example, valve actuators and certain end connections). The Russian edition is a translation intended for use by Russian-speaking manufacturers, test laboratories and users.

General information

• Status: Superseded (2018 edition subsequently included errata; later editions published — see API Std 6FA:2020).
• Publication date: Fourth edition, mid‑2018 (June/July 2018 — publication and translated formats vary by distributor).
• Publisher: American Petroleum Institute (API); Russian translation distributed by standards resellers/publishers.
• ICS / categories: Valves; fire testing; petroleum industry standards; valve qualification and testing procedures.
• Edition / version: 4th Edition (2018) — includes Errata 1 and Errata 2 in 2018 for the published text.
• Number of pages: Approximately 32–33 pages depending on format and translated layout.

Scope

Applies to valves manufactured to API 6A and API 6D specifications and other pressure-containing valves with one or more closure members that require verification of pressure-retention performance after exposure to fire. The standard defines the test fire exposure (30 minutes), the temperature/heat-flux conditions, allowable internal and external leakage limits during and after the test, and required documentation. It is not intended to qualify valve actuators, check valves, pressure boundary penetrations, certain external fittings or end connections unless explicitly stated.

Key topics and requirements

• Standardized 30‑minute fire exposure test method and furnace conditions for valve testing.
• Acceptance criteria for internal leakage (through the closure) and external leakage after fire exposure.
• Pre‑test setup, instrumentation and pressure-holding procedures; test pressure selection across sizes/ratings.
• Post‑test inspection, functional check procedures and required reporting items for test certificates.
• Scope exclusions and limitations (e.g., valve actuators, certain fittings and check valves are not covered).
• Inclusion of errata (Errata 1 and Errata 2) for the 2018 edition — users should consult the errata and any later revisions.

Typical use and users

Used by valve manufacturers for product qualification, by third‑party test laboratories performing fire tests, by procurement and QA/QC teams to specify valve fire‑test performance, and by operators and engineering contractors assessing valve selection for fire‑exposure risk in oil, gas and petrochemical installations. The Russian translation is intended to aid Russian-speaking stakeholders in understanding and applying the requirements.

Related standards

Commonly referenced standards include API 6A and API 6D (valve specifications), API 607 (fire testing for quarter‑turn valves and valves with nonmetallic seats), ISO 10497 (valve fire type-testing), and other API documents on valve testing and specification. Users should review these related standards for complementary requirements.

FAQ

Q: What is this standard?

A: API 6FA is the API standard that defines the method and acceptance criteria for fire testing pressure-containing valves; "St API St 6FA-2018 rus" denotes the Russian-language edition/translation of the 2018 (4th) edition.

Q: What does it cover?

A: It covers the prescribed fire exposure (30 minutes), furnace conditions, test pressures, allowable leakage limits, pre/post-test inspections, reporting requirements and exclusions for certain valve elements (e.g., actuators and some fittings).

Q: Who typically uses it?

A: Valve manufacturers, independent test laboratories, procurement and QA engineers in oil and gas, and operators or EPC contractors specifying valve fire-performance. The translation is for Russian-speaking practitioners.

Q: Is it current or superseded?

A: The 2018 (4th) edition has errata and was later incorporated into API documentation; a subsequent API Std 6FA:2020 edition was published, so users should check for the most recent edition and errata before relying on the 2018 translation.

Q: Is it part of a series?

A: Yes — API 6FA relates to a family of API valve standards (e.g., API 6A, API 6D) and to other valve testing standards such as API 607 and ISO 10497; it is used alongside valve specification documents.

Q: What are the key keywords?

A: Fire test, valves, API 6FA, valve qualification, leakage criteria, 30-minute fire exposure, errata, Russian translation.
