Full title and description

ASTM Research Report RR:D02-1733 (2011) — Intralaboratory study to establish a repeatability statement for ASTM D6743-11, "Standard Test Method for Thermal Stability of Organic Heat Transfer Fluids". This report documents the study design, test data, and statistical treatment used to derive the repeatability (r) for D6743-11.

Abstract

This research report summarizes an intralaboratory study performed to support a precision (repeatability) statement for ASTM Test Method D6743 (edition 2011). The study was carried out by a single laboratory which tested two representative heat‑transfer fluid samples; results, data processing and the derived repeatability statement are presented. The report is intended to provide the evidence base for the precision clause of D6743-11.

General information

• Status: Research report — published and available (ASTM research report RR:D02-1733, 2011).
• Publication date: Edition / approved date: December 1, 2011.

Scope

The report documents an intralaboratory (single‑laboratory) precision study performed to support the precision statement in ASTM D6743-11. It covers the samples tested, test conditions and procedures used under D6743, the raw and processed data, and the statistical analysis used to calculate repeatability metrics. Because the study involved only one laboratory and a small sample set, the report addresses repeatability (r) rather than inter‑laboratory reproducibility (R).

Key topics and requirements

• Overview of ASTM D6743 test method for thermal stability of organic heat transfer fluids and its application conditions.
• Study design for intralaboratory precision (sample selection, test repeats, controls).
• Data collection and reporting templates consistent with ASTM research‑report practice.
• Statistical treatment to derive repeatability (r) and statement of limits/uncertainty associated with r.
• Discussion of limitations due to single‑laboratory scope and small number of samples.

Typical use and users

Primary users are testing laboratories, heat‑transfer fluid manufacturers, quality assurance engineers, standards committees and product developers who need the precision statement for D6743 when reporting or comparing thermal‑stability test results. The report is used to interpret D6743 test results in the context of the method’s repeatability.

Related standards

This research report supports ASTM D6743 (thermal stability of organic heat transfer fluids), specifically the 2011 edition (D6743-11). Users should also consult other editions of D6743 and related D02 committee standards on non‑lubricating process fluids and heat‑transfer fluid testing for full context; more recent revisions of D6743 exist (for example D6743-20).

FAQ

Q: What is this standard?

A: This item is an ASTM Research Report (RR:D02-1733) — not a full consensus standard — that documents an intralaboratory study performed to establish the repeatability statement used in ASTM D6743-11, the test method for thermal stability of organic heat transfer fluids.

Q: What does it cover?

A: It covers the study design, samples tested, raw and processed data, and the statistical analysis used to derive the repeatability metric for D6743-11. The scope is limited to intralaboratory precision (single‑laboratory testing of two samples) and therefore addresses repeatability rather than full interlaboratory reproducibility.

Q: Who typically uses it?

A: Testing laboratories, manufacturers of heat‑transfer fluids, product qualification and QA teams, and members of ASTM Committee D02 who need to reference the empirical basis for the precision statement in D6743.

Q: Is it current or superseded?

A: The research report was published/approved in 2011 to support D6743-11. Research reports are archival records of a particular study; the underlying test method D6743 has had later revisions (for example D6743-20). Users should confirm and apply the latest edition of D6743 for testing and normative requirements.

Q: Is it part of a series?

A: It is one of a series of ASTM research reports produced by Committee D02 to provide precision/accuracy statements for specific test methods; its stock number is RR:D02-1733 and it specifically supports the D6743 test method.

Q: What are the key keywords?

A: Thermal stability; heat transfer fluids; D6743; repeatability; intralaboratory study; precision statement; ASTM research report RR:D02-1733.
