Full title and description

ASTM D2187-17 — Standard Test Methods and Practices for Evaluating Physical and Chemical Properties of Particulate Ion‑Exchange Resins. This standard compiles test practices and methods used to characterize particulate ion‑exchange resins (both cation and anion types) used for water treatment and related applications, including pretreatment, capacity, regeneration, particle size, density and common contaminant determinations.

Abstract

ASTM D2187-17 provides a collection of thirteen coordinated test methods and practices (designated A through M) that define laboratory procedures for determining key physical and chemical properties of particulate ion‑exchange resins. The standard is intended to support quality control, acceptance testing, comparative evaluation of new and used resins, and routine laboratory characterization used by manufacturers, utilities and independent test laboratories. It specifies sample pretreatment, water retention, density, particle‑size distribution, capacity measurements (total, salt‑splitting), regeneration assessments, and determinations of chloride, carbonate and sulfate content.

Scope

The standard covers laboratory test methods for determining the physical and chemical properties of particulate ion‑exchange resins when used for water treatment. It is applicable to both new and used resins and provides standardized procedures for pretreatment (conversion to a defined ionic form), measurement of water retention capacity, backwashed and settled density, particle‑size distribution, cation and anion exchange capacities (including salt‑splitting and total capacity), percent regeneration procedures, and for quantifying common anionic contaminants (chloride, carbonate, sulfate). SI units are primary; inch‑pound units are provided for information only. Safety and handling recommendations are noted where applicable.

Key topics and requirements

• Test Practice A — Pretreatment: convert resins to defined ionic forms (e.g., Na+ for cation, Cl− for anion) for uniform testing.
• Test Method B — Water Retention Capacity: determine equilibrium water content of resins.
• Test Method C — Backwashed and Settled Density: measure resin bed densities after backwashing and settling.
• Test Method D — Particle Size Distribution: wet‑sieve procedure for particle size fractions.
• Test Method E — Salt‑Splitting Capacity (cation resins): measurement of specific splitting behavior.
• Test Method F — Total Capacity of Cation‑Exchange Resins: determine total exchange capacity.
• Test Method G — Percent Regeneration of Hydrogen‑Form Cation Resins: quantify regeneration effectiveness.
• Test Method H — Total and Salt‑Splitting Capacity of Anion‑Exchange Resins: analogous capacity measurements for anion resins.
• Test Practice I — Percent Regeneration of Anion Resins: regeneration performance for anion types.
• Test Practice J — Ionic Chloride Content of Anion‑Exchange Resins: determine chloride contamination/content.
• Test Method K — Carbonate Content of Anion‑Exchange Resins: carbonate determination procedures.
• Test Method L — Sulfate Content of Anion‑Exchange Resins: sulfate determination procedures.
• Test Practice M — Total Anion Capacity: measure overall anion exchange capacity.
• General requirements: use of reagent‑grade chemicals, specified sample sizes and conditioning, reporting ionic form used, and adherence to SI units as the standard.

Typical use and users

Laboratories performing resin quality control and acceptance testing; manufacturers of ion‑exchange resins; water and wastewater treatment utilities; power plants and high‑purity water producers (e.g., boiler feedwater, ultrapure water systems); procurement/specification engineers; independent test houses and research organizations assessing resin condition, performance or degradation.

Related standards

Related ASTM standards and practices used alongside or for supplementary measurements include, but are not limited to: ASTM D6302 (evaluating kinetic behavior of ion‑exchange resins), ASTM D4266 (precoat capacity of powdered ion‑exchange resins), ASTM D4456 (physical and chemical properties of powdered ion exchange resins), ASTM D5627 (water‑extractable residue from particulate ion‑exchange resins). Earlier editions of D2187 (for example D2187‑94 and its reapprovals) are superseded by D2187‑17 and remain useful for historical comparison.
