Full title and description

St ASTM RR‑D02‑1543 (2003) — Research Report supporting ASTM D613, "Standard Test Method for Cetane Number of Diesel Fuel Oil". The report records an interlaboratory study run to establish precision/bias information for the D613 cetane-number test method.

Abstract

This research report (RR‑D02‑1543, approved May 6, 2003) documents an interlaboratory study in which 23 laboratories tested six diesel fuel samples to generate a precision statement for ASTM D613 (cetane number). The report summarizes test procedures used, data analysis, repeatability and reproducibility statistics, and recommendations for applying the precision statement in conformity and laboratory comparison work.

General information

• Status: Research report (archival supporting document for ASTM D613). Listed as an approved ASTM research report.
• Publication date: Research report approved May 6, 2003 (report year 2003).
• Publisher: ASTM International (Committee D02: Petroleum Products, Liquid Fuels, and Lubricants).
• ICS / categories: Petroleum and related technologies — ICS 75 (petroleum products and fuels), including 75.160 (fuels) / 75.160.20 (liquid fuels such as diesel).
• Edition / version: Research Report RR‑D02‑1543 (2003). It specifically documents the interlaboratory work for the then-current D613 procedure.
• Number of pages: Not specified in the public summary listing; typical ASTM research reports of this type are report‑length (commonly under 20 pages). Exact page count not listed in public product snippet (see note at end).

Scope

RR‑D02‑1543 provides the experimental dataset, statistical analysis, and derived precision (repeatability and reproducibility) statements for use with ASTM D613 (the cetane‑number engine test). The report covers sample selection, laboratory procedures as executed in the study, data treatment methods, outlier handling, and the recommended precision statement to be included with the D613 test method.

Key topics and requirements

• Interlaboratory study design and conduct for cetane-number measurement (number of labs, sample matrix, test conditions).
• Statistical treatment of results: repeatability and reproducibility calculations, outlier detection, and reporting conventions.
• Guidance for laboratories on applying the precision statement when using ASTM D613 for cetane-number determinations.
• Discussion of reference fuels, calibration/check fuels, and engine test apparatus variability impacting cetane results.
• Recommendations for future interlaboratory work and limitations observed in the study.

Typical use and users

Used by fuel and testing laboratories, refinery quality control and analytical groups, standards developers, engine and equipment manufacturers, regulatory agencies that reference ASTM methods (for example in fuel specification/regulatory contexts), and organizations performing method validation or round‑robin studies. The report supplies the precision statement that labs and regulators rely on when interpreting D613 results.

Related standards

Closely associated with ASTM D613 (Cetane Number). Related/commonly referenced standards include ASTM D975 (specification for diesel fuel oils), ASTM D976 (cetane index), ASTM D86 (distillation), and complementary methods for derived cetane number (e.g., ASTM D6890 and ISO 5165). Regulatory texts (EPA/CFR) reference D613 for cetane specifications in certain diesel fuel test fuels.

FAQ

Q: What is this standard?

A: RR‑D02‑1543 is an ASTM research report (approved May 6, 2003) that documents an interlaboratory study performed to derive precision statements for ASTM D613, the cetane‑number test method for diesel fuel oils.

Q: What does it cover?

A: It covers the design and results of the round‑robin testing (23 laboratories, six samples as reported in the public summary), statistical analysis of results, and the recommended repeatability and reproducibility values to accompany D613.

Q: Who typically uses it?

A: Fuel testing laboratories, refinery QC, standards committees, regulators and anyone needing the official precision statement for interpreting or comparing cetane‑number results from ASTM D613.

Q: Is it current or superseded?

A: RR‑D02‑1543 is the specific 2003 research report documenting that interlaboratory study; research reports are archival records of the study and remain historical support for the D613 precision statement. ASTM D613 itself has been revised several times since 2003 — consult ASTM International for the current active revision of D613. The research report remains the record of the 2003 study and is not itself a live "method" that is revised; subsequent studies or new RR documents may provide updated precision statements.

Q: Is it part of a series?

A: It is one of a sequence of D02 research reports (RR:D02‑####) that document round‑robin and validation studies for various D02 test methods. RR‑D02‑1543 specifically supports D613. Other RR:D02 reports support different D02 standards.

Q: What are the key keywords?

A: Cetane, cetane number, diesel fuel, D613, interlaboratory study, precision statement, repeatability, reproducibility, ASTM D02.
