Since its founding in 1926, one of the goals of the then water chemistry Division (now the Society of Water Chemistry). A revised and expanded edition was published in 1953 under the title "Deutsche Einheitsverfahren zur Wasseruntersuchung" (German Standard Procedures for Water Analysis). In 1960, the "Deutschen Einheitsverfahren zur Wasser-, Abwasser-, und Schlammuntersuchung" (German Standard Procedures for Water, Wastewater, and Sludge Analysis) were published as a loose-leaf collection, allowing individual regulations to be replaced with new versions as needed.

Since 1976, an agreement has existed between the Division and the DIN German Institute for Standardization (DIN), according to which the standard methods are gradually converted into DIN standards, and new standard methods are developed by the Society of Water Chemistry in cooperation with the Water Standards Committee. All DIN standards based on the standard methods are also published in this collection. In Technical Committee 147 "Water Quality" of the International Organization for Standardization (ISO), international standards on water quality are developed under German leadership. In some cases, these standards are incorporated into the German body of standards in the form of DIN-ISO standards; they are then also published in this collection. In the Comité Européen de Normalisation (CEN), European Standards (EN) for water analysis are developed under German leadership in Technical Committee 230. European standards generally replace existing DIN standards. European standards for water analysis are also included in this loose-leaf collection. By 2022, a total of 340 procedures had been standardized in one of the ways mentioned above.

A 0-4 – Estimation of relative or absolute measurement uncertainty
Created by: Dr. Michael Koch (University of Stuttgart)
Working aids for method A 0-4 "Guidelines for the estimation of measurement uncertainty from validation data" (64th edition, 2006, of the DEV), which later became the standard DIN ISO 11352. These aids provide a simple way to determine the relative or absolute measurement uncertainty of analytical results. Various validation data available in the laboratory, e.g., from control charts, can be entered. The result is the relative or absolute measurement uncertainty for the respective parameter.

A 100 – Test for limit violations
Prepared by: Dr. Michael Winterstein (WESSLING GmbH), Prof. Dr. Karl Molt (University of Duisburg-Essen)
Working aid for method A100, DIN SPEC 38402-100 German standard methods for the analysis of water, wastewater, and sludge – General information (Group A) – Part 100: Testing for limit violations taking measurement uncertainty into account using statistical and empirical methods.
