ASTM RR-D32-1017 1986 PDF

Full title and description

St ASTM RR-D32-1017 1986 — Research Report RR:D32-1017 (ASTM). This report documents an interlaboratory study conducted to support and establish the precision statement for ASTM Test Method D4164, "Test Method for Mechanically Tapped Packing Density of Formed Catalyst and Catalyst Carriers."

Abstract

The report (approved Feb 25, 1986) summarizes an interlaboratory program in which three participating laboratories measured mechanically tapped packing density on two reference materials. The document contains laboratory instructions, raw and reduced data, and the statistical analysis used to derive precision (repeatability and reproducibility) and bias information intended to support Test Method D4164.

General information

• Status: Approved ASTM Research Report (RR:D32-1017) supporting Test Method D4164; archival supporting data for the test method.
• Publication date: February 25, 1986.
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: Testing and measurement of catalyst materials; chemical/processing industry test methods; materials testing.
• Edition / version: Research Report RR:D32-1017 (1986) — corresponds to the D4164 test method precision support.
• Number of pages: About 21 pages (report length as listed in standard catalogs).

Scope

This research report provides the experimental details and statistical analyses from an interlaboratory study intended to produce the precision and bias statement for ASTM D4164. It documents participating laboratories, test samples and preparation, apparatus and procedures used for mechanically tapped packing density measurements, the raw data returned from each lab, and the statistical treatment (practice and methods used to calculate repeatability and reproducibility). The supporting data are filed at ASTM International and may be obtained from ASTM by request.

Key topics and requirements

• Mechanically tapped packing density measurement procedures for formed catalyst particles and catalyst carriers (extrudates, spheres, pellets).
• Interlaboratory study design and execution (three laboratories; two test materials).
• Data collection templates, apparatus descriptions, and laboratory instructions used during the round-robin.
• Statistical analysis to derive repeatability and reproducibility (precision) and evaluation of bias per ASTM interlaboratory practice.
• Supporting evidence used to justify the precision statement published in Test Method D4164.

Typical use and users

Primary users of this research report are standards developers and technical committees (ASTM Committee D32 and subcommittees), analytical and quality-control laboratories at catalyst manufacturers and carriers, process engineers in refining and petrochemical industries, and laboratories performing acceptance or comparative testing of formed catalyst materials. The report is most often consulted when interpreting the precision statement of D4164 or when reproducing the interlaboratory procedures.

Related standards

This research report directly supports ASTM D4164 (Test Method for Mechanically Tapped Packing Density of Formed Catalyst and Catalyst Carriers). It is related to other D32 committee test methods on catalyst properties and packing density such as D4180 (vibratory packing density), D4699 (vibratory packing density of larger formed catalyst particles), and later bulk-strength/abrasion methods (for example D7084 and related RR documents).

FAQ

Q: What is this standard?

A: This item is an ASTM Research Report (RR:D32-1017) published in 1986 that documents an interlaboratory study used to establish the precision statement for ASTM Test Method D4164 (mechanically tapped packing density of formed catalyst and catalyst carriers).

Q: What does it cover?

A: It covers the round‑robin test plan, laboratory instructions, apparatus descriptions, raw data, and statistical analysis used to produce repeatability and reproducibility values (the precision statement) for the D4164 test procedure. Supporting data are held by ASTM and may be requested.

Q: Who typically uses it?

A: Standards committees (ASTM D32), QA/QC and analytical labs at catalyst manufacturers, refiners and petrochemical companies, and researchers who need the interlaboratory background or precision data for D4164.

Q: Is it current or superseded?

A: The research report itself is a historical supporting document issued in 1986. The D4164 test method it supports has been maintained and revised over time (D4164 includes later revisions; for example recent versions of D4164 exist). The research report remains the archived interlaboratory record for the precision statement it established; for the latest normative text of D4164 consult the current ASTM D4164 edition.

Q: Is it part of a series?

A: Yes — it is one of a sequence of ASTM Research Reports produced by Committee D32 (catalogued as RR:D32-####) that support precision and bias statements for numerous catalyst test methods.

Q: What are the key keywords?

A: Mechanically tapped packing density; catalyst; catalyst carrier; packing density; interlaboratory study; precision; repeatability; reproducibility; ASTM D4164.
