ISO 5208

4 in-depth engineering guides on ISO 5208 — specification, selection, testing and procurement.

Everything on ISO 5208

Vajra's engineering team has published 4 technical guides covering ISO 5208 for industrial valve selection, specification, testing and procurement. Browse the full set below.

Factory Acceptance Testing (FAT) for Industrial Valves - API 598, ISO 5208 and Witness Testing Guide

Factory Acceptance Testing (FAT) verifies that every valve meets its specified pressure-temperature rating and leakage class before leaving the manufacturer's facility. API 598, ISO 5208, and EN 12266 define the test procedures - this guide covers what is tested, acceptable leakage limits, and how third-party witness inspection works.

Industrial Valve Hydrostatic Testing Procedures - API 598, ISO 5208 & EN 12266

Factory Acceptance Testing (FAT) of industrial valves involves shell pressure testing and seat leakage testing per API 598, ISO 5208, or EN 12266. Understanding the test pressures, durations, and acceptance criteria ensures you specify the right tests and interpret results correctly.

Valve Testing and Inspection: API 598, ISO 5208, Hydrostatic & Seat Tests

Every industrial valve must pass mandatory pressure tests before despatch - but the test pressures, durations, and acceptance criteria differ significantly between API 598 and ISO 5208. This guide explains hydrostatic shell tests, seat leakage tests, backseat tests, TPI (third-party inspection) requirements, and the full documentation package expected for critical service valves.

Valve Testing and Inspection Standards: API 598, ISO 5208, and BS 6755

Every industrial valve must be pressure-tested before shipment to verify structural integrity and seat leakage. API 598, ISO 5208, and BS 6755 define the test pressures, durations, and acceptance criteria that differentiate a certified valve from a questionable one.
