Full title and description

ASTM D4057-22 — Standard Practice for Manual Sampling of Petroleum and Petroleum Products. This practice specifies procedures, apparatus, and container selection for obtaining representative manual samples of liquid, semi-liquid, and some solid-state petroleum and petroleum products, including guidance for handling free water and heavy components associated with hydrocarbon streams.

Abstract

Provides standardized, industry-accepted manual sampling methods to produce representative samples for laboratory analysis, custody transfer, quality control, and regulatory compliance. The practice includes safety and health precautions, sampling devices and equipment, sample container selection and preparation, procedures for spot and running samples, and special considerations for semi-solid materials; it also notes exclusions and cross-references to complementary methods for volatility, mixing, and specialty samples.

Scope

The practice covers manual sampling procedures and equipment for obtaining representative samples of liquid petroleum, petroleum products, crude oils, and intermediate streams from sample points into primary containers. It includes techniques for sampling free water and heavy components, addresses semi-liquid and some solid-state products, and provides guidance on container selection, preparation, and sample handling. The practice excludes certain fluids (for example, electrical insulating oils and hydraulic fluids) and refers users to other practices for precision volatile determinations, mixing/handling, and specific product types.

Key topics and requirements

• Objective and concepts of manual sampling (spot, running, and all-level samples) to ensure representativeness.
• Health, safety, and environmental precautions specific to sampling operations (static hazards, sample-point safety, PPE and regulatory considerations).
• Apparatus, sampling devices, and accessories (design and use of samplers, probes, and fittings).
• Sample container selection, cleaning, preparation, closure, and labeling requirements to avoid contamination and preserve analyte integrity.
• Procedures for sampling free water and other heavy phases; guidance on level measurement and avoiding entrainment.
• Guidance on sampling semi-liquid/solid materials and cross-references to specialized practices (e.g., petroleum coke sampling).
• Notes on units (SI as primary, U.S. customary in parentheses) and on chain-of-custody considerations with references to additional guides.

Typical use and users

Used by laboratory analysts, refinery and terminal operators, pipeline and marine cargo sampling personnel, quality-control and inspection teams, custody-transfer specialists, and regulatory/compliance auditors. Also referenced by technical staff preparing sampling procedures and by trainers; ASTM offers associated training and e-learning for implementers.

Q: What does it cover?

A: It covers procedures, equipment, container selection and preparation, safety precautions, and special considerations (free water, heavy phases, semi-solid material), while excluding certain niche fluids and pointing to other practices for specialized analyses.

Q: Who typically uses it?

A: Laboratory analysts, refinery and terminal sampling staff, pipeline and marine cargo sampling personnel, custody-transfer teams, QA/QC engineers, and regulatory/compliance auditors. ASTM also provides training for practitioners.

Q: Is it current or superseded?
