Full title and description

St ASTM RR‑D02‑1601 (1999) — Research Report supporting ASTM D6733: "Standard Test Method for Determination of Individual Components in Spark‑Ignition Engine Fuels by 50‑Metre Capillary High Resolution Gas Chromatography." The report documents an interlaboratory cooperative study conducted to establish the precision statement for Test Method D6733 (27 laboratories, seven test samples; report approved September 3, 1999).

Abstract

This research report (RR:D02‑1601) summarizes the design, sample set, laboratory instructions, raw data and statistical analysis from an interlaboratory study intended to validate and produce precision and bias statements for Test Method D6733 (50‑metre capillary high‑resolution GC for gasoline component speciation). The study results support the application limits, repeatability and reproducibility statements used in the D6733 standard.

Scope

RR:D02‑1601 documents an interlaboratory study whose scope was to determine method precision (repeatability and reproducibility) for D6733, which covers determination of individual hydrocarbon components in spark‑ignition (gasoline) engine fuels and related light blending stocks up to a given boiling range (about 225 °C). The test method is applicable to component concentrations typically in the range 0.10 % to 15 % by mass and includes caveats on co‑elution and oxygenated blends.

Key topics and requirements

• Interlaboratory study design and protocol to establish precision statements for D6733 (27 participating laboratories; seven samples tested).
• Description of sample selection, preparation and distribution used in the round‑robin study.
• High‑resolution gas chromatographic conditions for a 50‑metre capillary column and reporting conventions for individual hydrocarbon components (D6733 method details).
• Statistical analysis used to derive repeatability and reproducibility limits and the resulting precision statement for the method.
• Limitations and notes on co‑elution (examples: benzene/two‑component co‑elution issues) and applicability to oxygenated gasoline blends and PONA‑type groupings.

Typical use and users

Primary users are analytical and quality laboratories in refineries, fuel producers, independent testing laboratories, regulatory agencies and research organizations that require detailed hydrocarbon speciation (detailed hydrocarbon analysis, DHA) for gasoline and light petroleum streams. The research report is used by method developers and laboratory managers to understand the interlaboratory precision underpinning the D6733 test method and to guide method implementation and quality control.

Related standards

The research report is directly associated with ASTM D6733 (the test method it supports). The D6733 scope also references related methods for certain analytes or interferences (examples: Test Methods D5599 and D4815 for oxygenates, Test Methods D3606 or D5580 for benzene/toluene where co‑elution occurs, and Test Method D1319 for bulk olefin measurement). Users should consider these companion methods when interpreting results or addressing co‑elution/oxygenate issues.

FAQ

Q: What is this standard?

A: This item is a research report (RR:D02‑1601, 1999) published by ASTM International that documents an interlaboratory cooperative study performed to establish the precision (repeatability and reproducibility) for ASTM Test Method D6733 (50‑metre capillary high‑resolution GC for gasoline component determination).

Q: What does it cover?

A: The report covers the study design, participating laboratories, sample descriptions, laboratory instructions, raw data and the statistical analysis used to produce the precision statement for D6733. In practical terms it supports use of the D6733 procedure for quantitative reporting of many individual hydrocarbon components in spark‑ignition engine fuels and related blending stocks.

Q: Who typically uses it?

A: Fuel testing and refinery analytical laboratories, independent testing bodies, standards developers, and regulators use the research report to understand method performance and to justify or verify method implementation and QC criteria for D6733 analyses.

Q: Is it current or superseded?

A: The research report itself documents the 1999 interlaboratory study and remains the supporting precision record for that study. The D6733 test method has been maintained and revised since its original adoption; the D6733 series has later reapprovals and revisions (including 2016 reapprovals and a more recent D6733‑24 revision). Users should consult the current D6733 standard edition for the active method text and note that the RR documents the original interlaboratory precision data.

Q: Is it part of a series?

A: Yes — RR:D02‑1601 is one of the ASTM Research Reports produced by Committee D02 (Petroleum Products, Liquid Fuels and Lubricants) that document interlaboratory studies used to establish precision and bias statements for many D02 test methods; it specifically supports D6733. Other related RRs and later precision studies for similar GC/DHA methods exist within the D02 research report series.

Q: What are the key keywords?

A: Detailed hydrocarbon analysis (DHA), gasoline speciation, 50‑metre capillary, high‑resolution gas chromatography, interlaboratory study, precision statement, repeatability, reproducibility, ASTM D6733, RR:D02‑1601.
