Treatment of swimming and bathing pool water
Commentary on DIN 19643

(Please note that this publication is only available in German.)

Perfectly hygienic water quality in swimming pools is enormously important and is of great significance for the protection of bathers and employees. DIN 19643 summarizes the requirements that must be met in order to achieve this goal. This standard is extremely widely used: Almost all public and commercial pools work on the basis of DIN 19643; its importance is emphasized by the German Federal Environment Agency.

DIN Media provides this practical commentary on the standard in order to optimize the implementation of the specifications and instructions contained in DIN 19643. It is intended to provide valuable assistance in the application of the five-part standard and has been compiled by recognized experts in the field, whose theoretical knowledge and practical expertise have been incorporated into this commentary.

In “Treatment of swimming and bathing pool water” you will find:

• Text of the DIN 19643 standard commented in detail clause by clause
• illustrative practical examples
• Background knowledge and information, e.g. on microbiological and chemical quality requirements
   

Expert knowledge for the practical application of standards

The DIN 19643 series  is of particular importance because it bridges a regulatory gap that has arisen due to the current lack of a valid legal regulation for swimming and bathing pool water. It is intended to provide those with responsibilities in swimming and bathing establishments as well as inspectors and institutions with the necessary guidance for ensuring water quality. The sensible and correct implementation of these standards in practice protects people and businesses, and this commentary contributes to this with the following:

• Clear structure
  The commentary is provided in the standard clauses themselves. The notes and explanations, practical tips and background information are presented in clearly separated chapters.
   
• Great practical relevance
  The commentary was written by experts who have many years of experience in practical work in hygiene, swimming pool operation and water quality, as well as theoretical and standardisation knowledge. It therefore addresses exactly what operators really need commentary on and clarifies the specific questions that arise in practice.
   
• Valuable background knowledge
  The team of authors is largely involved in the DIN standardization processes through standards and working committees; expert knowledge and pool consulting activities also mean that this commentary contains both theoretical principles and important background information for practical operation.

“Treatment of swimming and bathing pool water” is a well-founded, comprehensive commentary that serves as a guide for perfectly hygienic operation and takes scientific, normative and practical aspects into account in equal measure.
