Recommends procedures for crude oil and liquid petroleum products being conveyed by pipeline. Does not apply to liquefied petroleum gases and liquefied natural gases. The principal purpose ist to give guidelines for specifying, testing, operating, maintaining and monitoring crude oil samples.

Abstract

Overview

Key topics and technical requirements

Scope and purpose: Guidelines to obtain representative samples for composition, water and sediment content, density and other properties (with precautions for specific tests).
Sampling principles: Need for homogeneity at the sampling point; preference for automatic sampling when pipeline conditions vary; role of sample integrity and conditioning.
Sampler types: Definitions and differences between intermittent (grab) and continuous samplers; the requirement for proportional sampling (time‑proportional or flow‑proportional).
Sampling point selection & stream conditioning: Guidance on locating probes, use of mixers (static, powered, variable-geometry) and ensuring adequate dispersion upstream of the probe.
Profile testing: Multi‑point sampling across a pipe diameter to verify cross‑sectional uniformity and suitability of a sampling location.
Probe, sampler and control design: Requirements for probe geometry, sampler installation, control equipment and maintaining proportionality to pipeline flow.
Flow measurement & sample receivers: Considerations for accurate flow-proportional sampling, receiver and container design to preserve sample integrity.
Sample handling & safety: Conditioning, transfer, division and transport practices and precautions for hazardous fluids.
Validation & uncertainty: Procedures for proving sampling systems (field tests) and methods to estimate overall sampling‑system uncertainty; performance classification is included.

Practical applications and users

Pipeline operators and terminals use EN ISO 3171:1999 to design and validate automatic sampling systems for crude oil and refined product transfers.
Oil companies and traders rely on representative samples for quality control, analytical results (water, sediments, density) and commercial reconciliation.
Equipment manufacturers and system integrators reference the standard when designing probes, samplers, mixers and control systems.
Laboratories and quality assurance teams implement sample handling and conditioning requirements to preserve sample integrity.
Regulatory and safety teams use the safety and procedural guidance when sampling hazardous petroleum liquids.
