GOST 14363.3-84 PDF

Full title and description

GOST 14363.3-84 — "Pulp and wood pulp. Determination of dirts and shives." This Soviet / CIS national standard specifies a laboratory method for estimating visible non-fibrous contaminants (dirts) and shives in pulp and wood-pulp samples. The document is available in Russian and English translations and is published as a 7‑page technical standard.

Abstract

GOST 14363.3-84 defines a standardized procedure for preparing pulp samples and inspecting them in transmitted light to count and classify specks (dirts) and shives by area class, then reporting the result relative to the dry mass of the pulp. The method is intended for routine quality control and acceptance testing in pulp production and processing.

Scope

This standard applies to pulp and wood-pulp and establishes a method for determining the "sorostnost" (dirt/shive content) by inspection in transmitted light. The procedure covers sample preparation (wet or cast samples), visual inspection to detect specks visible to the unaided eye, classification of specks by area using a template, and calculation of dirt/shive content expressed relative to a reference dry-mass basis. Use is primarily for laboratory quality-control and acceptance testing of pulp lots.

Key topics and requirements

• Definitions and terminology for "dirt" (non-fibrous inclusions) and "shive" (wood slivers or fiber bundles) with minimum detectable sizes and area thresholds.
• Sample collection and preparation rules (wetting, casting or laboratory-sheet preparation) to ensure representative inspection.
• Inspection method in transmitted light: counting visible specks on prepared samples and classifying them by area classes using a reference template.
• Calculation and reporting: convert counts and classified areas to a standard result expressed per unit of absolutely dry pulp mass.
• Requirements for illumination, viewing device or viewer, and basic handling to avoid contamination during inspection.
• References and alignment with international practices for dirt/shive estimation (methods in the ISO 5350 series are conceptually similar — transmitted- and reflected-light inspection variants).

Key method elements and classification approach align with established international test practice for pulp dirt/shive estimation. Where ISO counterparts exist (ISO 5350 series), they describe comparable transmitted- and reflected‑light inspection techniques and classification by area.

Typical use and users

Primary users are pulp mills, pulp quality laboratories, paper mills that receive pulps, independent testing laboratories, procurement and acceptance inspectors, and research groups working on pulp cleanliness and recycling. Typical uses include incoming pulp acceptance tests, process control (screening, cleaning, repulping performance), troubleshooting contamination sources, and specification compliance checks between suppliers and buyers.

Related standards

Relevant and related documents include earlier national versions replaced by this edition (GOST 14363.3-70), other parts of the GOST 14363 series, and international standards dealing with dirt and shive estimation such as the ISO 5350 series (Parts 1–3 covering transmitted and reflected light inspection of laboratory and mill sheets). National terminology standards for pulp and paper (e.g., later GOST/GOST‑R terminology standards) are also commonly referenced alongside this method.

FAQ

Q: What is this standard?

A: GOST 14363.3-84 is a national standard that specifies a laboratory method for determining the amount of visible dirts and shives in pulp and wood‑pulp samples. It is a focused test-method document used in the pulp and paper industry for cleanliness assessment.

Q: What does it cover?

A: It covers sample preparation (wetting or casting of samples), inspection in transmitted light to detect specks visible to the naked eye, classification of specks by area using a template, and calculation/reporting of dirt and shive content referenced to dry pulp mass. The method is intended for routine laboratory QC and acceptance testing.

Q: Who typically uses it?

A: Pulp mills, paper mills that evaluate incoming pulps, quality-control and analytical laboratories, standards bodies, and procurement/inspection personnel use this standard to quantify and communicate pulp cleanliness. Independent testing houses and research labs working on pulp contamination or recycling also apply this method.

Q: Is it current or superseded?

A: The standard is listed in national catalogs as active (действующий). It replaced an earlier version (GOST 14363.3-70) and has recorded amendments and reprints; catalog entries show reissue/updates and at least one amendment documented in the national information system. Users should consult the current national registry or the published text to confirm the present legal/applicability status for contractual use.

Q: Is it part of a series?

A: Yes — it is one part of the broader GOST 14363 group of standards addressing pulp and related test methods; it also has conceptual kinship with the ISO 5350 series (pulps — estimation of dirt and shives), which covers complementary inspection methods (transmitted and reflected light).

Q: What are the key keywords?

A: Pulp, wood pulp, dirt, shive, sorostnost, transmitted light inspection, laboratory sheet, pulp quality, pulp testing, GOST 14363.3-84.
