ASTM RR-E05-0001 1994 PDF

Full title and description

St ASTM RR-E05-0001 1994 — ASTM Research Report RR:E05-0001 (associated with ASTM E399: "Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness of Metallic Materials"). The report documents an interlaboratory study used to establish the precision (and related statistical statements) for the ASTM E399 test method.

Abstract

This research report (RR:E05-0001) compiles the protocol, participating-laboratory data, raw measurements, and statistical analyses from an interlaboratory round-robin on fracture-toughness testing to produce an ASTM precision and bias statement for the E399 test method. The study described tests by multiple laboratories on several reference materials (interlaboratory summary: nine laboratories testing four materials is reported on the ASTM product page). The report is intended as a supporting document to E399 and to inform users of expected repeatability and reproducibility for K_Ic measurements under the specified test conditions.

• Edition / version: Marketed/cataloged as RR:E05-0001 (1994 listed by some vendors); see ASTM for the authoritative edition/approval metadata.
• Number of pages: Approx. 20–50 pages (varies by formatting/print or PDF distribution). (Approximate — consult ASTM product listing for the delivered format.)

Scope

The report provides the interlaboratory data, laboratory instructions, specimen descriptions, apparatus information, raw test records, and statistical summaries used to develop or support the precision and bias statement for ASTM E399 (linear‑elastic plane‑strain fracture toughness testing of metallic materials). It covers the experimental design, specimen geometries used (typical E399 specimen types such as C(T) and SE(B) are referenced), fatigue precracking practice used in the study, and the methods used to calculate and interpret K_Ic and related parameters.

Key topics and requirements

• Purpose and rationale for the interlaboratory study (precision and bias determination for E399).
• Description of participating laboratories, test instructions, and quality‑control measures used in the round‑robin.
• Specimen types and preparation (common E399 geometries such as compact tension and single‑edge bend specimens), fatigue precracking procedures and acceptance criteria.
• Data collection formats: load vs. displacement records, crack size measurement, and reporting templates.
• Statistical analysis methods used to compute repeatability, reproducibility, and precision/bias statements for fracture‑toughness results.
• Discussion of validity criteria and common sources of variability (e.g., residual stress, specimen machining, precrack quality).

Typical use and users

Used by fracture‑mechanics laboratories, materials testing facilities, metallurgical researchers, quality/control engineers, standards committees, and organizations that specify or verify K_Ic values for metallic components. Typical uses include method validation, round‑robin performance benchmarking, and informing acceptance criteria or uncertainty estimates for fracture toughness testing in research and industrial settings.

FAQ

Q: What is this standard?

A: It is an ASTM research report (RR:E05-0001) that documents an interlaboratory study used to establish precision and bias information for the ASTM E399 test method (linear‑elastic plane‑strain fracture toughness of metallic materials).

Q: What does it cover?

A: The report covers laboratory instructions, specimen descriptions, raw test data, statistical summaries, and the calculations used to derive repeatability/reproducibility statements for K_Ic testing under the protocol associated with E399. It is a supporting document, not the normative text of E399 itself.

Q: Who typically uses it?

A: Fracture mechanics and materials testing laboratories, standards developers, quality engineers, and researchers who need validated precision estimates or who are comparing lab performance for E399 testing.

Q: Is it current or superseded?

A: There is some cataloging ambiguity in third‑party listings that show "1994" for RR‑E05‑0001; however, the ASTM product/catalog records for RR:E05-0001 and for the E399 standard should be treated as authoritative. ASTM’s E399 has been revised (current ASTM E399-24 as cataloged by ASTM) and the research report entry is available in ASTM’s research‑report catalog — consult the ASTM Digital Library or ASTM customer service for the definitive approval/publication metadata.

Q: Is it part of a series?

A: Yes — RR:E05-0001 is one of the ASTM Research Reports produced to support E‑section test methods; it is listed with other E05/E08 series research reports that document interlaboratory studies for fracture and fire standards. The RR:E05 series items are cataloged under committee E08 (Fatigue and Fracture) / E05 listings in ASTM’s research‑report catalog.

Q: What are the key keywords?

A: Fracture toughness, K_Ic, plane‑strain, interlaboratory study, precision, reproducibility, ASTM E399, metallic materials, research report, RR:E05-0001.
