Full title and description

Chemicals used for treatment of water intended for human consumption — Aluminium-based coagulants — Analytical methods. This document is the British adoption (BS EN) of EN 1302:2024 and specifies analytical and sampling methods, expressions of results and quality control procedures for aluminium-based coagulants used in drinking-water treatment.

Abstract

EN 1302:2024 defines laboratory analytical methods for aluminium-based coagulants (for example aluminium sulphate, sodium aluminate and polyaluminium products) used to treat water intended for human consumption. The standard covers sampling, determination of aluminium content and other relevant chemical parameters, presentation of results and references the product standards in which the coagulants are specified. It is intended to support manufacturers, laboratories and regulators in demonstrating conformity and monitoring product quality.

Scope

This standard is applicable to aluminium-based coagulants used for the treatment of water intended for human consumption. It specifies analytical methods to be used for products described in EN 878, EN 882, EN 885, EN 886, EN 887, EN 935 and EN 17034 and provides guidance on sampling, sample preparation, test procedures and how to express and report results for quality control and conformity assessment.

Key topics and requirements

• Defined analytical procedures for determination of aluminium content (primary assay methods and alternatives).
• Methods for key chemical parameters and impurities relevant to coagulant quality (for example chloride, sulphate and other specified constituents where applicable).
• Sampling and sample preparation rules to ensure representative testing and repeatability.
• Instructions on expression of results, units, calculation of uncertainties and reporting for conformity and quality control.
• Normative and informative annexes listing detailed test procedures and possible alternative techniques (complexometric titrations, spectrometric or other validated methods where indicated).

Typical use and users

Laboratories performing product testing, manufacturers of aluminium-based coagulants, water utilities and treatment plant operators, regulatory bodies and conformity assessment bodies use this standard to ensure analytical results are consistent, comparable and suitable for product specification, regulatory compliance and quality control.

Related standards

This standard is directly linked to product standards and test-method families for water-treatment chemicals, notably EN 878, EN 882, EN 885, EN 886, EN 887, EN 935 and EN 17034; it replaces or updates earlier editions of EN 1302 (1999 family) and is part of the suite of standards for chemicals used in drinking-water treatment.

FAQ

Q: What is this standard?

A: BS EN 1302:2024 is the British-adopted version of the European standard EN 1302:2024 specifying analytical methods for aluminium-based coagulants used in the treatment of water intended for human consumption.

Q: What does it cover?

A: It covers sampling, laboratory test procedures, methods for determining aluminium content and other relevant chemical parameters, how to express and report results, and references to the product standards that define the coagulants.

Q: Who typically uses it?

A: Manufacturers, testing laboratories, water utilities, regulators and conformity assessment bodies concerned with the quality and specification of aluminium-based coagulants for drinking-water treatment.

Q: Is it current or superseded?

A: EN 1302:2024 is the current edition (published December 2024) and replaces the earlier EN 1302:1999 (with corrigendum). National adoptions such as BS EN 1302:2024 reflect this update.

Q: Is it part of a series?

A: Yes — it is part of the family of European standards for chemicals used in the treatment of water intended for human consumption and is specifically linked to product standards EN 878, EN 882, EN 885, EN 886, EN 887, EN 935 and EN 17034 which define the products to which these analytical methods apply.
