Full title and description

GOST 12026-76 — Laboratory filter paper. Specifications (Russian: Бумага фильтровальная лабораторная. Технические условия). This Soviet-era standard specifies technical requirements, grades and sizes, test methods, acceptance rules, marking, packaging, transportation and storage for laboratory filter paper used in qualitative and quantitative analyses.

Abstract

GOST 12026-76 defines the characteristics and quality requirements for laboratory filter papers (including ashless grades intended for quantitative analysis), prescribes methods of testing filtration and separation performance, and sets rules for acceptance, marking and packaging. It was prepared under the USSR national standards system and contains short-form technical and inspection provisions for laboratory-grade filter papers.

General information

• Status: Sources vary: some databases list the standard as active/in-force, while others record it as withdrawn or superseded in national registries (historical GOST from the USSR). Users should check their national standards body for current national adoption.
• Publication date: Designated 12026-76 (adopted 1976); official introduction/implementation date shown as 01 January 1978 in several catalogs.
• Publisher: Developed under the USSR State Committee for Standards (Gosstandart) / prepared by the Ministry of the Forest Industry of the USSR; originally published by the Standards Publishing House.
• ICS / categories: 85.060 — Paper and board (laboratory filter paper classification).
• Edition / version: GOST 12026-76 (original 1976 text) with subsequent text amendments/changes recorded (noted amendments/errata in 1978, 1981, 1987, 1989 in catalogues).
• Number of pages: 7 pages (typical commercial/registry listings show a short 7-page technical specification).

Scope

The standard applies to laboratory filter paper intended for general laboratory work and for both qualitative and quantitative chemical analyses. It covers ashless papers specifically intended for preparing circular, ashless filters for quantitative determinations and broader filter-paper grades for routine clarification of waters, solutions and oils. The document sets out required physical and chemical properties, test methods for filtration and separation behaviour, inspection and acceptance criteria, and rules for marking, packing, transport and storage.

Key topics and requirements

• Definition of grades and nominal sizes of laboratory filter paper (including ashless "quantitative" grades).
• Technical requirements: allowed ash content (for ashless grades), tensile strength, thickness, filtration and separation characteristics, and purity criteria for laboratory use.
• Methods of sampling and test methods for determining filtering and separating ability and ash content.
• Acceptance rules: inspection procedures, criteria for lot acceptance or rejection.
• Marking, packaging, transportation and storage requirements appropriate for laboratory consumables.
• References and normative links to related test and materials standards (methods for ash determination and other referenced GOSTs).

Typical use and users

Used by chemical, environmental and industrial laboratories, academic research labs, water and wastewater testing facilities, oil and petroleum testing labs, and manufacturers of laboratory consumables and filter papers. Quality-control and production laboratories in paper mills consult the standard when producing and certifying laboratory-grade filter papers.

Related standards

References and related documents cited in registries include earlier and related GOSTs such as the predecessor GOST 12026-66, GOST 7629 (methods for ash determination and related test methods), and other GOSTs on paper and testing methods. National or regional catalogues may list additional normative links depending on adoption.

A: GOST 12026-76 is a Soviet technical standard titled "Laboratory filter paper. Specifications" that defines requirements, test methods and handling rules for laboratory filter papers.

Q: What does it cover?

A: It covers grades and sizes of laboratory filter paper (including ashless grades for quantitative analysis), technical and chemical requirements (e.g., ash content for ashless paper), filtration and separation test methods, acceptance rules, and marking/packaging/transport/storage requirements.

Q: Who typically uses it?

A: Chemical and environmental labs, academic and industrial testing laboratories, filter-paper manufacturers and QC departments use this standard as a specification for producing or selecting laboratory-grade filter paper.

Q: Is it current or superseded?

A: Catalogues and registries are inconsistent: some databases list GOST 12026-76 as active/in-force in their collections, while others mark it as withdrawn or replaced in national registries. Users should verify the current legal or normative status with their national standards body or standards distributor for their country and application.
