ASTM D1214-10 (2020) PDF

Full title and description

ASTM D1214-10(2020) — Standard Test Method for Sieve Analysis of Glass Spheres. This test method specifies procedures for performing sieve analysis on glass spheres (beads) used primarily in retroreflective pavement markings and other industrial applications to determine size distribution and conformance to product specifications.

Abstract

This standard defines the sample preparation, selection of test sieves, sieving procedure, calculation and reporting of size distribution for glass spheres. The information is used to quantify bead gradation as a measurable attribute affecting retroreflective performance and to verify compliance with contractual or specification limits. The method is compact (five pages) and includes normative references to general ASTM practices for sieves and precision statements.

Scope

The scope covers sieve analysis of glass spheres used for retroreflective pavement markings and other industrial uses. It establishes SI units as normative, notes any safety responsibilities of the user, and points to related ASTM practices for sieves and precision reporting. The method is intended for measuring bead size/gradation as an aspect of performance and specification compliance.

Key topics and requirements

• Sample preparation and representative sampling procedures for glass spheres.
• Selection and use of test sieves (normative reference to ASTM E11 for sieve specifications).
• Sieving procedure, mass retention by sieve, and calculation of percent retained/passing to produce size distribution curves or tables.
• Reporting requirements: units (SI normative), method identification, and any deviations from the prescribed procedure.
• Precision and bias considerations; an interlaboratory research report (RR:D01-1150) establishes precision characteristics for the method.
• Notes on significance for retroreflective performance and use outside pavement-marking applications where appropriate.

Typical use and users

Used by materials laboratories, pavement-marking manufacturers and suppliers, quality control / QA personnel, transportation agencies, and testing laboratories responsible for verifying bead gradation for retroreflective pavement marking materials and related industrial bead applications. It is commonly used when bead size distribution is a specified acceptance criterion.

Related standards

Commonly referenced standards include ASTM E11 (Specification for Woven Wire Test Sieve Cloth and Test Sieves) and ASTM E177 (Practice for Use of the Terms Precision and Bias), plus related traffic/retroreflective specifications (for example ASTM sign or sheeting specifications used by agencies). The method’s document history also cross-references prior D1214 editions and editorial amendments.

FAQ

Q: What is this standard?

A: ASTM D1214-10(2020) is the ASTM Standard Test Method for Sieve Analysis of Glass Spheres, a short procedural standard for measuring the particle-size distribution of glass beads used primarily in retroreflective pavement markings.

Q: What does it cover?

A: It covers sample preparation, selection and use of sieves, sieving procedure, calculation of percent retained/passing, and reporting of bead size distribution. SI units are normative and users are reminded to follow applicable safety and environmental practices.

Q: Who typically uses it?

A: Manufacturers of glass beads and pavement-marking materials, third‑party testing labs, state and municipal transportation agencies, and QA/QC teams that need to verify bead gradation against specifications.

Q: Is it current or superseded?

A: The 2010 method was reaffirmed and published as D1214-10(2020) (reaffirmation date June 1, 2020) and is listed as active/reapproved. Users should check with ASTM for any amendments or more recent revisions beyond the 2020 reaffirmation.

Q: Is it part of a series?

A: It is part of the ASTM D01 committee’s suite of standards covering paint and related coatings and materials; specifically it relates to traffic coatings and retroreflective materials and is maintained by Subcommittee D01.44 (Traffic Coatings). It also references general ASTM practices (for sieves and precision).
