GOST R 55227-2012 PDF

Full title and description

GOST R 55227-2012 — "Вода. Методы определения содержания формальдегида" (English: "Water. Methods for determination of formaldehyde content"). The standard specifies laboratory methods for determining formaldehyde mass concentration in drinking, surface, groundwater and wastewater samples.

Abstract

GOST R 55227-2012 defines three analytical procedures (photometric, HPLC, and fluorimetric) with specified measurement ranges, sampling and preservation requirements, calibration and quality-control practices, and rules for choosing the arbitration method depending on concentration and sample type. It is intended to provide reproducible, traceable methods for formaldehyde determination in various water matrices.

Scope

The standard applies to drinking water (including bottled water), natural surface and groundwater, and wastewater (including treated effluents). It establishes three validated analytical methods for formaldehyde determination and sets rules for sampling, sample preservation, calibration and quality control, and selection of the arbitration method depending on concentration and sample type.

Key topics and requirements

• Photometric method (Method A) — applicable ranges: approx. 0.025–25 mg/dm3 for drinking/natural waters and 0.05–400 mg/dm3 for wastewater samples; intended for routine determinations.
• High-performance liquid chromatography (HPLC) method (Method B) — higher-sensitivity chromatographic procedure for approx. 0.002–10 mg/dm3 (used as arbitration for low concentrations in potable and natural waters).
• Fluorimetric method (Method C) — applicable range approx. 0.02–50 mg/dm3 for potable, natural and wastewater samples; used as arbitration at higher concentrations for some sample types.
• Sampling and preservation — glass containers recommended; avoid phenol‑formaldehyde resin caps; if analysis >12 hours after sampling, acidify/preserve and refrigerate according to the method instructions.
• Calibration and QA — linear calibration characteristics required (correlation coefficient not less than 0.98 for HPLC calibration), routine checks of calibration stability, column/instrument checks, and criteria for acceptance of results.
• Method selection rules — the standard specifies which method is arbitration for particular concentration ranges and sample types to harmonize reporting and dispute resolution.

Typical use and users

Analytical and environmental testing laboratories, water utilities and treatment facilities, regulatory bodies, manufacturers and developers of analytical instrumentation and reagents, and organizations conducting compliance testing for drinking water and wastewater quality. The methods are used for routine monitoring, research and regulatory compliance testing.
