ASTM RR-D02-1320 1994 PDF

Full title and description

ASTM Research Report RR:D02-1320 (1994) — Research report providing interlaboratory supporting data and a precision statement for the 1M‑PC single‑cylinder diesel engine test procedure (used in evaluation of engine oils). This report documents the test program, participating laboratories, test samples and the statistical analysis used to establish precision for the referenced test method.

Abstract

This research report (RR:D02‑1320), approved March 8, 1994, summarizes an interlaboratory study carried out to establish a precision statement for the ASTM single‑cylinder 1M‑PC engine test procedure used to evaluate diesel engine oils. The study describes the test engine configuration, sample preparation, test protocol followed by participating laboratories, results and the statistical treatment used to derive repeatability and reproducibility estimates.

Scope

Provides supporting interlaboratory data and the precision statement for the ASTM 1M‑PC single‑cylinder diesel engine test method used to evaluate engine oils. The report covers test hardware and instrumentation, sample handling, test procedures followed by participating laboratories, raw results, and the statistical methods used to compute repeatability and reproducibility for the test. It is intended to document the reliability of the 1M‑PC procedure when used across multiple laboratories.

Key topics and requirements

• Interlaboratory study design and scope (number of laboratories, test samples, test matrix).
• Description of the 1M‑PC single‑cylinder diesel engine test apparatus and essential instrumentation.
• Detailed test procedure and sample conditioning/handling requirements used by participating labs.
• Statistical analysis methods applied to derive repeatability and reproducibility (precision statement) for the referenced test method.
• Recommendations and limitations for use of the precision statement in method validation and performance specifications.

Typical use and users

Used by test laboratories, lubricant formulators, engine OEMs, qualification and certification bodies, and standards committees that reference engine oil performance testing. The report is primarily a reference document for laboratories implementing the 1M‑PC test and for spec writers who need documented precision for that test method.

Related standards

Directly supports the ASTM test procedure for evaluation of engine oils in the 1M‑PC single‑cylinder engine (standard D6618 and related method entries). It is also cited in engine oil performance specifications and compilations that list required test procedures (for example, tables in engine‑oil performance specifications that reference research reports used to establish test precision). Users should consult the current editions of D6618 and relevant ASTM performance specifications for cross‑references.

FAQ

Q: What is this standard?

A: This is an ASTM research report (RR:D02‑1320) published in 1994 that documents an interlaboratory program and provides the precision statement for the 1M‑PC single‑cylinder engine test method used in evaluation of diesel engine oils. It is a supporting document rather than a standalone test method.

Q: What does it cover?

A: It covers the experimental design, participating laboratories, test procedure as executed in the study, raw and processed results, and the statistical analysis used to derive repeatability and reproducibility estimates for the referenced 1M‑PC engine test.

Q: Who typically uses it?

A: Accredited and commercial test laboratories, lubricant manufacturers and formulators, engine OEMs, quality assurance and specification writers, and ASTM committee members use the report to understand the expected variability of the 1M‑PC test and to interpret test results in a regulatory or specification context.

Q: Is it current or superseded?

A: The report itself was approved March 8, 1994 and remains the published supporting research report RR:D02‑1320 for the referenced test method. Because research reports are supporting documentation, users should verify the current status of the associated test standard (for example D6618 or any standard that references RR:D02‑1320) with ASTM International to confirm whether the method or its precision statement has been updated or superseded.

Q: Is it part of a series?

A: Yes — RR:D02‑1320 is one of many ASTM Research Reports produced by Committee D02 (RR:D02 series) that document interlaboratory studies and precision statements for petroleum, lubricant and engine‑test methods. Other RR:D02 reports document precision for additional test methods and engines.

Q: What are the key keywords?

A: Key keywords include RR:D02‑1320, 1M‑PC, D6618, engine oil, interlaboratory study, precision statement, ASTM Research Report, diesel single‑cylinder test.
