ASTM D2009-65 (1990) PDF

Full title and description

St ASTM D2009-65 (1990) — Practice for Collection by Filtration and Determination of Mass, Number, and Optical Sizing of Atmospheric Particulates. This ASTM practice describes procedures for collecting airborne particulate matter on filters and for subsequent determination of particulate mass, particle number concentration, and particle sizing using optical techniques and ancillary measurements.

Abstract

This practice defines a filter-based sampling and analysis workflow for atmospheric particulates, combining gravimetric (mass) determination with particle counting/number concentration and optical sizing approaches. It covers filter selection, sampling configuration, sample handling, conditioning and weighing, optical sizing instrument basics as applied to collected samples, and recommended reporting elements. The designation shown indicates original issue in 1965 with a 1990 reapproval/version notation (ASTM D2009-65 (1990)). The practice has since been withdrawn from active ASTM listings.

General information

• Status: Withdrawn (withdrawal recorded in the mid-1990s).
• Publication date: Original issue 1965; shown/reapproved designation includes 1990 (ASTM D2009-65 (1990)).
• Publisher: ASTM International (formerly American Society for Testing and Materials).
• ICS / categories: Air quality and environmental monitoring (typical ICS grouping: air and climate / environmental protection).
• Edition / version: Designation indicates 1965 original with 1990 reapproval notation — commonly cited as ASTM D2009-65 (1990).
• Number of pages: Short practice (reported length ~7 pages in standard catalog listings).

Scope

This practice applies to the collection of ambient atmospheric particulate matter by filtration onto suitable filters and to subsequent laboratory determinations of particulate mass (gravimetric), particle number (counting), and particle-size characterization using optical techniques. It is intended for routine environmental monitoring and research where filter collection is appropriate. It does not replace reference regulatory methods for specific regulated metrics (for example the current federal reference methods for PM2.5/PM10) and does not cover in-line continuous monitoring instruments when operated independently of collected filter analysis.

Key topics and requirements

• Selection and preparation of sampling filters (material, porosity, preconditioning).
• Filter-handling, contamination control, and sample transport procedures.
• Gravimetric determination: conditioning, precision balance use, blank corrections, and mass calculation.
• Particle-number determination: approaches to counting particles removed from filters or inferred from filter deposits.
• Optical sizing concepts as applied to particles collected on filters (light-scattering/optical microscopy approaches, instrument calibration and limitations).
• Quality assurance: calibration, replicate samples, method precision, and reporting conventions.
• Recommended reporting elements: sample site, flow rates, sampling duration, filter type, mass results, size/number summaries and uncertainty notes.

Typical use and users

Used historically by environmental testing laboratories, university research groups studying atmospheric aerosols, municipal and regional air quality monitoring programs, and industrial hygiene teams conducting spot or campaign sampling. Typical users include laboratory analysts, environmental scientists, instrument specialists, and regulatory program staff who need a filter-based comparative practice for mass plus sizing/number characterization.

Related standards

Related documents and standards commonly referenced alongside this practice include other ASTM D-series methods for particulate sampling and measurement, national/regulatory particulate reference methods (for example federal reference methods and federal equivalence methods for PM2.5 and PM10), and ISO standards addressing particle size terminology and measurement. Users migrating from this withdrawn practice typically consult current ASTM and ISO particulate-monitoring and aerosol-measurement standards as well as EPA reference methods for regulated particulate metrics.

FAQ

Q: What is this standard?

A: ASTM D2009-65 (1990) is a practice for collecting atmospheric particulates by filtration and determining particulate mass, number, and optical sizing characteristics. Its designation reflects an original 1965 issue with a 1990 reapproval notation.

Q: What does it cover?

A: It covers filter selection and preparation, sampling procedure and flow control, filter conditioning and gravimetric mass determination, approaches to particle counting and optical sizing of collected material, and basic quality-assurance and reporting recommendations for filter-based particulate characterization.

Q: Who typically uses it?

A: Environmental laboratories, academic aerosol researchers, air quality program staff, and industrial hygiene practitioners who perform filter-based particulate sampling and need combined mass and sizing/number characterization.

Q: Is it current or superseded?

A: The practice is recorded as withdrawn in the mid-1990s and should be treated as superseded or obsolete for current regulatory compliance. For contemporary monitoring and regulatory work, consult current ASTM, ISO, and national reference methods (for example modern PM2.5/PM10 FRM/FEM procedures) and newer ASTM aerosol/particulate standards.

Q: Is it part of a series?

A: It belongs to the broader set of ASTM D-series standards dealing with environmental and particulate testing practices. Users often reference related D-series practices and test methods when assembling a complete particulate-monitoring program.
