GOST 1625-89
Name in Russian:
ГОСТ 1625-89
Formalin for industrial use. Specifications
Full title and description
GOST 1625-89 — "Formalin for industrial use. Specifications" (ГОСТ 1625-89, Формалин технический. Технические условия). A state (interstate) standard that defines grades, composition, quality requirements, testing, packaging, storage and safety/transport provisions for technical formalin (aqueous methanol-stabilized solutions of formaldehyde) used in industry and for export.
Abstract
This standard specifies technical requirements and test methods for industrial formalin (aqueous solutions of formaldehyde stabilized with methanol). It covers permitted concentrations, limits for impurities (for example formic acid, iron and non‑volatile residue), physical and chemical properties, sampling and laboratory control, marking, packaging, storage and transportation rules, and safety/occupational hygiene references. GOST 1625-89 was later superseded by a 2016 revision (GOST 1625-2016).
General information

- Publication date: Designation year 1989; effective date (introduction) 01 January 1991; withdrawal/expiry noted 01 July 2017.
- Publisher: State Standard (Gosstandart) — originally USSR / interstate standard; later maintained in Russian national collections.
- ICS / categories: ICS 71.080.80 (Aldehydes and ketones) — chemical products; OKS/industry code often listed as 71.080.80.
- Edition / version: GOST 1625-89 (1989 edition); replaced by GOST 1625-2016.
- Number of pages: Approximately 18 pages (text and tables depending on publication).
Scope
Applies to technical formalin — aqueous solutions of formaldehyde intended for industrial uses and export. The standard sets requirements for composition and quality (including formaldehyde mass fraction, allowable methanol stabilizer ranges, impurity limits and physical properties), prescribes sampling and analytical methods for laboratory control, and specifies packaging, marking, storage and transport rules as well as cross-references to safety and occupational standards.
Key topics and requirements
- Definitions and classification of technical formalin grades (typical nominal formaldehyde content such as ~37% by mass).
- Permitted ranges for stabilizer (methanol) and limits for impurities (formic acid, iron, non‑volatile residue, etc.).
- Physical and chemical property requirements (appearance, density, freezing/boiling behavior, odor).
- Sampling procedures and required test methods for determining formaldehyde content and impurity levels.
- Requirements for packaging, marking and storage conditions to ensure product stability and safety.
- Transport and handling precautions and cross-references to relevant occupational safety and environmental GOSTs/standards.
Typical use and users
Used by chemical manufacturers and suppliers of formalin, quality control and analytical laboratories, product purchasers in industries such as resin and polymer production (urea‑ and phenol‑formaldehyde resins), textiles, leather/tanning, paper and pulp, agriculture (disinfection), embalming and anatomical laboratories, and regulatory/standards bodies overseeing chemical product compliance and trade.
Related standards
Key related documents include the previous version GOST 1625-75 and the replacing standard GOST 1625-2016. The standard references several occupational safety and testing standards (for example standards on chemical safety and analytical methods used for impurity and content determination) and is related by ICS to other chemical-product standards in the 71.080 series (aldehydes and ketones).

FAQ
Q: What is this standard?
A: GOST 1625-89 is a state/interstate specification for technical formalin (aqueous formaldehyde solutions) that sets composition, quality, testing, packaging and handling requirements for industrial use.
Q: What does it cover?
A: It covers grades and nominal composition (formaldehyde content), limits for impurities and stabilizers, required physical and chemical properties, sampling and test methods, marking, packaging, storage and transport, plus links to safety/occupational rules.
Q: Who typically uses it?
A: Chemical producers, distributors, laboratories performing quality control, downstream users in resin/adhesive, textile, leather, paper and agricultural sectors, and regulatory/standards organizations involved in conformity assessment and trade.
Q: Is it current or superseded?
A: GOST 1625-89 has been superseded — it was replaced by a revised standard (GOST 1625-2016). The 1989 text remains of historical or transitional interest but the 2016 version is the current normative reference for formalin requirements.
Q: Is it part of a series?
A: Yes — it belongs to chemical-product standards in the 71.080 ICS subgroup (organic chemicals — specifically aldehydes and ketones). It also follows earlier national versions (e.g., GOST 1625-75) and is linked to subsequent updates (GOST 1625-2016).
Q: What are the key keywords?
A: Formalin; formaldehyde; technical formalin; methanol; specification; quality control; GOST 1625-89; aldehydes and ketones; industrial chemical.
