Overview
SIST EN 15469:2008 is a European standard developed by CEN for testing the presence of free water in liquefied petroleum gas (LPG) through visual inspection. This standard defines a precise method using a pressure transparent cylinder to detect free water in LPG samples at temperatures below 0 °C. It helps ensure product quality and equipment safety by identifying water contamination in LPG, which can cause corrosion and operational blockages.
Key Topics
Scope and Purpose
The standard covers a visual inspection test method to identify free water in LPG using a pressure cylinder. This test is applied below 0 °C to detect ice formation, which indicates free water presence.Terminology
LPG is defined as petroleum gas stored or handled in liquid phase under moderate pressure and temperature, mainly consisting of propane, butanes, and small amounts of propene, butenes, and pentanes/pentenes.Principle
A sample is collected in a transparent pressure cylinder filled to 50% capacity, cooled for at least one hour below 0 °C, and visually inspected for ice lumps representing frozen free water.Significance
Detecting free water is critical because water in LPG can cause corrosion and freeze to block valves, pumps, and regulators, impacting safety and operations.Apparatus Requirements
- Transparent pressure container (~250 ml) fitted with bottom and vent valves
- Suitable thermometer in contact with the liquid
- Freezer capable of maintaining below 0 °C temperatures
- Proper cleaning solvents (e.g., ethanol or isopropanol) for apparatus preparation
Testing Procedure
- Pre-cool the test cylinder before sample introduction
- Transfer LPG sample carefully avoiding water entrapment
- Cool sample in freezer horizontally for at least one hour
- Observe immediately for ice lumps on the cylinder surface
- Record pass/fail results based on ice presence
Report Format
Results are reported as pass if no ice is observed (no free water) or fail if ice lumps appear (free water detected).Precision
The test is qualitative with a pass/fail outcome; therefore, quantitative precision is not specified.
Applications
SIST EN 15469:2008 is essential for industries involved in the production, storage, transportation, and distribution of liquefied petroleum gas. Practical applications include:
Quality Control
Ensuring LPG batches meet water content requirements before release or further processing.Safety Assurance
Preventing corrosion-related equipment damage and operational failures caused by ice blockages.Maintenance Planning
Scheduling cleaning or filtration if free water is detected to maintain system integrity.
This test method supports safe handling of LPG in residential, commercial, and industrial settings by minimizing water-induced risks.
