Description (English):

ISO 20764:2003 specifies two procedures for the preparation of test portions from petroleum and related products boiling above 200 degrees Celsius, which can then be used for the determination of total water content within the range of 3 mg/kg to 1 000 mg/kg. The method is applicable to unused and used lubricating oils, non-aqueous hydraulic fluids and high-boiling solvents. The test portions generated by these procedures are suitable for standard Karl Fischer water-content determinations, such as those described in ISO 6296 and ISO 12937.

Abstract

Overview

EN ISO 20764:2003 - Petroleum and related products: Preparation of a test portion of high‑boiling liquids for the determination of water content - Nitrogen purge method (ISO 20764:2003) defines laboratory procedures to prepare test portions from petroleum and related materials boiling above 200 °C for subsequent water content determination. The standard covers two nitrogen‑purge extraction procedures (atmospheric pressure and reduced pressure) to generate samples suitable for Karl Fischer titration over the range 3 mg/kg to 1 000 mg/kg. It applies to unused and used lubricating oils, non‑aqueous hydraulic fluids and high‑boiling solvents.

Key Topics and Requirements

Scope and applicability: High‑boiling petroleum products (>200 °C), lubricating oils, hydraulic fluids, high‑boiling solvents. Target water range 3–1 000 mg/kg.
Two extraction procedures:
- Atmospheric pressure method: nitrogen purge at 120 °C, typical duration 60 ± 5 min.
- Reduced pressure method: nitrogen purge at 60 °C under vacuum 0.30–0.65 kPa, typical duration 90 ± 5 min (for used oils or materials with high water retention).
Reagents and gases: Pure, dried nitrogen (flow ~3 L/h ± 0.3 L/h; oxygen
