GOST 10898.2-74 PDF

Full title and description

GOST 10898.2-74 — "Ion-exchange resins. Determination of bulk density" (Russian: "Иониты. Метод определения насыпной массы"). The standard specifies a laboratory method for determining the bulk (apparent) density of ion‑exchange resins used in industrial and analytical applications.

Abstract

This standard defines the scope, sampling, apparatus and procedural steps required to measure the bulk (packed) density of ion‑exchange resins. It is intended to provide a reproducible test for quality control, specification verification and reporting of bulk density values for both wet and dry resin samples where applicable. The document is part of the GOST series on ion‑exchange resins (series 10898).

General information

• Status: Active / in force (document listed as действующий in current GOST catalogs and vendors' databases).
• Publication date: Designation year 1974 (suffix -74). Introduction / effective date reported as 1 July 1975 in official catalogues; some vendor records show early‑1975 adoption dates (sources vary).
• Publisher / developer: Developed under the USSR chemical industry authorities; issued under the authority of the State Committee for Standards of the USSR (Gosstandart) / relevant Soviet standards bodies.
• ICS / categories: Classified to chemical products / products of the chemical industry — catalogue listings show classification code 71.100 (OKS / category for chemical industry products).
• Edition / version: Original GOST designation 10898.2-74; later collections and consolidated publications group it with related 10898 series standards (see related standards). Amendments/changes have been recorded in vendor metadata (e.g., amendment references).
• Number of pages: Records differ between vendors and catalogues — single‑page core text is reported by some providers, while multi‑page compilations (6–8 pages) appear when bundled with other 10898-series documents. See notes below for details.

Scope

Applies to ion‑exchange resins (ionites) and specifies a laboratory procedure for determining their bulk (apparent, packed) density. The method is intended for use in production quality control, acceptance testing and technical specification verification for both industrial and laboratory samples of ion‑exchange resins. It does not replace methods for true density, porosity or specific surface determinations, which are covered in related parts of the 10898 series.

Key topics and requirements

• Definition of bulk (packed) density for ion‑exchange resins and its reporting conventions.
• Sampling and sample preparation rules to obtain representative material for the test (avoiding segregation, proper draining/conditioning for wet resins).
• Required apparatus (measuring container of specified internal dimensions or calibrated cylinder, balance with stated accuracy, timing and filling tools) and environmental/temperature conditions for the measurement.
• Step‑by‑step procedure for filling the measuring vessel, leveling/striking off the resin, reading mass/volume and calculating bulk density (mass divided by occupied volume), with instructions for repeat measurements and averaging.
• Reporting requirements: test conditions, sample state (wet/dry), measured bulk density (units), and any deviations or corrections applied.

Typical use and users

Used by chemical manufacturers of ion‑exchange resins, quality control and analytical laboratories, procurement and inspection agencies, and end‑users who specify resin performance (water treatment, separation, catalysis, chromatography). The test supports batch acceptance, specification compliance and packing/transport considerations where bulk density affects process design and handling.

FAQ

Q: What is this standard?

A: GOST 10898.2‑74 is a Soviet (GOST) test method titled "Ion‑exchange resins. Determination of bulk density" that specifies how to measure the bulk (packed) density of ion‑exchange resins for quality and specification purposes.

Q: What does it cover?

A: It covers sampling considerations, required apparatus, procedural steps for filling and reading a calibrated vessel, calculation of bulk density (mass/volume) and reporting of results for ion‑exchange resins. It is focused on apparent/bulk density rather than true skeletal density or surface/porosity metrics.

Q: Who typically uses it?

A: Resin manufacturers, incoming inspection and QC laboratories, chemical process engineers, and purchasers or specifiers of ion‑exchange resins who need reproducible packed‑density data for process design, packing calculations and acceptance testing.

Q: Is it current or superseded?

A: Multiple catalogues and standards vendors list GOST 10898.2‑74 as active (действует) and available; however, presentation, bundling and editorial updates differ among providers. Users should verify whether a national adoption, amendment or a newer national standard has superseded the GOST text for their jurisdiction before use in regulatory or contractual settings. The original GOST designation is -74 with introduction reported in 1975.

Q: Is it part of a series?

A: Yes — it belongs to the 10898 series of standards on ion‑exchange resins (for example 10898.1‑84, 10898.4‑84, 10898.5‑84), which jointly cover moisture, bulk and specific volume, surface, granulometry and related physico‑chemical test methods.

Q: What are the key keywords?

A: Ion‑exchange resins; ionites; bulk density; packed density; nasypnaya massa; test method; GOST; quality control.

Note on bibliographic discrepancies: public vendor/catalog records vary on small bibliographic points (exact introduction date shown as 07.01.1975 on some listings and 01.07.1975 on others; page counts appear as 1 page in some vendor files and 6–8 pages when bundled with other 10898 documents). If you need the precise official printed text, edition or amendment status for certification or regulatory use, request the official scanned cover page or retrieve the standard from the national standards body or an authorized standards provider to confirm the exact edition and any amendments.
