Full title and description

DIN EN 12396-2:1998-12 — Non-fatty foods — Determination of dithiocarbamate and thiuram disulfide residues — Part 2: Gas chromatographic method. This document is the German (DIN) adoption of the CEN/EN method specifying a gas‑chromatographic procedure to quantify residues of dithiocarbamates and thiuram disulfides in non‑fatty foods; the method measures the total residue as carbon disulfide released under the prescribed conditions rather than identifying individual active ingredients.

Abstract

This standard defines a laboratory method using gas chromatography (GC) to determine total residues of dithiocarbamate and thiuram‑disulfide pesticides (e.g., mancozeb, maneb, propineb, thiram, zineb) in and on fruits, some vegetables, cereals and other plant‑origin, non‑fatty foodstuffs. It covers principle, reagents, apparatus, sampling, sample preparation, procedure, expression of results, precision and confirmatory tests; results are usually reported as carbon disulfide (CS2) equivalents.

Scope

The standard specifies a gas‑chromatographic analytical procedure for determining residues of dithiocarbamate and thiuram‑disulfide pesticide groups that liberate carbon disulfide under the method conditions. It is applicable to residues in or on fruits, selected vegetables, cereals and other foods of plant origin that are non‑fatty. The method quantifies the entire group as CS2 equivalents; it does not provide unambiguous identification of individual active substances. Normative references and confirmatory/precision requirements are included to support laboratory implementation.

Key topics and requirements

• Gas chromatography (GC) measurement of carbon disulfide released from treated samples.
• Sample collection and preparation procedures tailored for non‑fatty food matrices.
• Required reagents, apparatus and GC operating conditions (including informative annex with suggested GC settings).
• Calibration and expression of results as CS2 equivalents (group quantification rather than compound‑specific identification).
• Precision, repeatability and reproducibility statements and recommended confirmatory tests.

Typical use and users

Analytical and commercial testing laboratories, food safety/regulatory authorities, research institutions studying pesticide residues, quality‑assurance teams in food production and import/export control labs use this standard to check compliance with maximum residue limits (MRLs) and to monitor group residues of dithiocarbamates/thiurams in non‑fatty food matrices.

Related standards

Part of a family of CEN methods and multiresidue procedures. Commonly referenced related standards include: EN 12396-1 (Part 1 — Spectrometric method for the same residue group), EN 12393-1 (multiresidue GC — general considerations), EN 12393-3 (later multiresidue/confirmatory approaches for plant origin foods). Laboratories should consult these and any later CEN or national updates when implementing methods.

FAQ

Q: What is this standard?

A: DIN EN 12396-2:1998-12 is the German national adoption of the CEN method EN 12396-2:1998 titled "Non‑fatty foods — Determination of dithiocarbamate and thiuram disulfide residues — Part 2: Gas chromatographic method." It defines a GC procedure to quantify these groups of residues in non‑fatty foods.

Q: What does it cover?

A: The standard covers principle, reagents, apparatus, sampling, sample preparation, analytical procedure, expression of results (reported as CS2 equivalents), precision and confirmatory tests for dithiocarbamate and thiuram residues in plant‑origin, non‑fatty food matrices. It quantifies the group as a whole rather than identifying individual active ingredients.

Q: Who typically uses it?

A: Food testing laboratories, regulatory laboratories and agencies, food producers performing internal quality checks, and research labs engaged in pesticide residue monitoring and method validation.

Q: Is it current or superseded?

A: EN 12396-2:1998 is the cited EN document and has been adopted nationally by several bodies (e.g., DIN EN 12396-2:1998-12). National catalogues list it as the implemented text; however, users should always confirm in their national standards catalogue or with their national standards body whether a more recent revision or replacement exists for their country before use.

Q: Is it part of a series?

A: Yes — it is Part 2 of the EN 12396 series dealing with dithiocarbamate/thiuram residues (Part 1 covers a spectrometric method). It also sits alongside CEN multiresidue standards such as EN 12393 series for broader GC/LC multiresidue methods and confirmatory testing.

Q: What are the key keywords?

A: dithiocarbamates, thiurams, carbon disulfide (CS2), gas chromatography, pesticide residues, non‑fatty foods, EN 12396-2, DIN EN.
