Full title and description
ISO 10574:1993 — Refrigerated light‑hydrocarbon fluids — Measurement of liquid levels in tanks containing liquefied gases — Float‑type level gauges. The standard specifies essential requirements and verification procedures for float‑type level gauges used in ship and shore tanks for refrigerated light hydrocarbon fluids.
Abstract
Defines the functional and verification requirements for float‑type level gauges (including those operated by servomechanism) intended to measure liquid levels in tanks containing liquefied light hydrocarbon gases under refrigerated conditions. The document covers performance criteria, test and verification procedures and reporting for the gauges.

Scope
Specifies essential requirements, verification procedures, reference standards, equipment calibration and checking, acceptance criteria and test reporting for float‑type level gauges used to measure liquid levels in tanks containing liquefied light hydrocarbon gases (refrigerated). The scope covers both shipboard and shore (land) tanks and includes float gauges operated directly or via servomechanisms.
Key topics and requirements
- Performance and accuracy requirements for float‑type level gauges used with refrigerated light hydrocarbon fluids.
- Verification and test procedures, including calibration and acceptance checks.
- Requirements for gauges operated by servomechanisms and associated control interfaces.
- Environmental and operational conditions relevant to ship and shore tanks (temperature, pressure, product characteristics).
- Reporting and documentation of verification results and any required markings.
Typical use and users
Used by manufacturers of float‑type level gauges, maritime and shore terminal operators handling refrigerated light hydrocarbon liquids (e.g., LPG/LHC carriers and terminals), marine and tank instrumentation engineers, testing and certification bodies, and procurement/specification engineers responsible for tank gauging equipment.
Related standards
ISO 10574:1993 has been superseded by the ISO 18132 series (ISO 18132‑1:2006 and ISO 18132‑2:2008) which consolidate and update requirements for automatic level gauges used with refrigerated light hydrocarbon fluids; related documents such as ISO 8309 and ISO 13689 were also taken into account in later revisions.

FAQ
Q: What is this standard?
A: ISO 10574:1993 is an International Standard that specified requirements and verification procedures for float‑type level gauges used to measure liquid levels in tanks containing refrigerated light hydrocarbon gases.
Q: What does it cover?
A: It covers performance criteria, calibration and checking procedures, test and verification methods, acceptance criteria and reporting for float‑type level gauges (including those driven by servomechanisms) for ship and shore tanks storing liquefied light hydrocarbon fluids.
Q: Who typically uses it?
A: Gauge manufacturers, marine and terminal operators handling refrigerated light hydrocarbon liquids, instrumentation engineers, testing/certification bodies and procurement/specification professionals.
Q: Is it current or superseded?
A: ISO 10574:1993 has been withdrawn and superseded by the ISO 18132 series (parts 1 and 2 published 2006 and 2008 respectively), which provide updated and consolidated requirements for automatic level gauges for refrigerated light hydrocarbon fluids.
