ASTM RR-D02-1013 1975 PDF

Full title and description

ASTM Research Report RR:D02-1013 — D2624: Test Methods for Electrical Conductivity of Aviation and Distillate Fuels (research report approved September 11, 1975). The report documents an interlaboratory study undertaken to develop precision information and evaluate portable conductivity meters used with the D2624 test method.

Abstract

This research report summarizes an interlaboratory program in which five laboratories tested seven fuel samples to establish a precision statement for ASTM D2624. Measurements were made using portable conductivity meters (notably three Ethyl meters and two Maihak meters) and the report presents the resulting precision and measurement observations relevant to conducting and interpreting D2624 tests.

Scope

RR:D02-1013 documents an interlaboratory precision study carried out to support and quantify the precision characteristics of ASTM D2624 (electrical conductivity test methods for aviation and distillate fuels). The work focused on portable meter measurements taken on circulated samples to assess repeatability/reproducibility and practical measurement issues (meter types, sample stability and handling). The results were used as part of the empirical basis for later precision statements and related collaborative studies for D2624.

Key topics and requirements

• Interlaboratory precision and repeatability data for D2624 measurements.
• Comparison of portable conductivity meters (recorded use of Ethyl and Maihak meters).
• Sample handling, stability over time, and effects on measured conductivity.
• Recommendations and data used to inform precision statements in later revisions of D2624 and related RR reports.

Typical use and users

Used by petroleum/fuel testing laboratories, instrument manufacturers, refining and jet-fuel producers, aviation fuel quality assurance groups, and standards committees interested in the precision and performance of conductivity measurement methods for safety and specification compliance.

FAQ

Q: What is this standard?

A: RR:D02-1013 is an ASTM research report (approved September 11, 1975) documenting an interlaboratory study performed to develop precision information for the D2624 test methods for electrical conductivity of aviation and distillate fuels.

Q: What does it cover?

A: It covers the design and results of a collaborative test program (five laboratories, seven samples) that compared portable conductivity meter measurements, evaluated sample handling and stability issues, and provided data used to characterize the precision and reproducibility of D2624 measurements.

Q: Who typically uses it?

A: Fuel testing laboratories, quality assurance groups in refineries and airlines, instrument manufacturers, and standards developers use the report as historical precision data and as background when interpreting or revising D2624 test procedures.

Q: Is it current or superseded?

A: RR:D02-1013 is a historical research report (1975). It is a primary data source for early precision information but later collaborative reports and revisions of D2624 (and associated RR documents) expanded and updated precision statements; users should consult the current D2624 standard and later RR reports for the most recent precision/reproducibility data.
