Such water is to be compared to the water originally conveyed by the system to see if there is a significant difference in quality, as described in DVGW W April Number of pages: This standard does not cover corrosion which leads to component damage, nor does it deal with the assessment of the suitability of lined steel water heaters with or without internal cathodic protection.

Table 2 lists the limit values specified in the Trinkwasserverordnung for various components and materials.

There are no limitations for the use of unalloyed steel, hot-dip galvanized steel, stainless steel, copper and copper alloys for water heaters, due to the low B values of the heaters, as long as they are operated as intended i. This standard describes the influence of material characteristics, water-related parameters and operating conditions on the quality of drinking water in contact with metallic materials used in water supply systems, particularly where corrosion products are relevant to water quality, and where limit values are specified in the Trinkwasserverordnung.

Criteria are also given here for assessing the suitability of metallic materials for use in water supply systems; these criteria are based on investigations and practical experience.

DIN series is not to be used to prepare food. July Number of pages: For undated references, the latest edition of the publication referred to applies.

Guidance on social responsibility. Classification of low corrosivity of indoor atmospheres. Determination of corrosion attack in indoor atmospheres. These values relate to samples representative of the average water consumption over the period of a week.

When assessing water whose composition changes over time, time series data are more significant than maximum and minimum values.

The parameters listed in table 1 are to be known when evaluating their influence on changes in drinking water quality due to the presence of corrosion 5090, particularly as regards the suitability of the water for human consumption. Changes due to corrosion are largely determined by the length of time the water stagnates and the age of the installation. The results of the analysis are to be checked for plausibility. Don water parameters which promote surface corrosion also affect the water quality.

Vitrified clay pipes systems for drain and sewers – Part 6: To ensure this, there should be continuous flow in the system, and the flow should be laminar or turbulent. As the effect of metallic materials on the quality of drinking water is not covered by these standards, DIN has been introduced at the national level.

Unlike corrosion damage to components, corrosion damage to the water itself cannot generally be rectified 59030 making alterations to operating conditions or changing waterrelated parameters.

When this happens, however, corrosion products in dissolved or solid form are released into the drinking water. Where phosphorus and silicon compounds are fed centrally, the phosphorus and silicon contents are to be stated separately.

B values for various components and materials B Sanitary valves and pipe fittings including compression couplings of Cu-Sn-Zn alloys or Cu-Zn alloys, in systems of any material Adaptors and connectors of Cu-Sn-Zn alloys or Cu-Zn alloys in systems where other elements are made of the same material Pipe fittings, adaptors and connectors of Cu-Sn-Zn alloys or Cu-Zn alloys for use in service lines of plastics Pipe fittings, adaptors and connectors of Cu-Sn-Zn alloys or Cu-Zn alloys for use in systems e.

For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. These changes are due to microbiotic processes, as well as to the materials with which the water is in contact. The mean value represents the corrosion loading of the drinking water under the given test conditions, and is the basis for assessing the suitability of a material, component or water treatment method in terms of fulfilment of the requirements specified in the Trinkwasserverordnung.

Assessments may be made either on the basis of the information given in clause 8 or on the basis of data obtained in measurements carried out as specified in DIN Certification of persons Do recognize your skills, register online to become certified.

There are no limitations for the use of small pipe and valve components e. Register online at inter and intra-company training, and certifying diplomas, seminars, distance learning. Protective measures may, however, be taken to prevent damage due to ineffective water treatment or the use of unsuitable materials.
