Vinyl chloride 0.50 g/l µ B Parameter need not be parsed, but is to be calculated if the risk mapping in section 6 shows that the parameter can be relevant. The maximum amount of monomers is calculated from what the specifications say about polymerens transfer to the drinking water on contact.

Schedule 2 Action limits Action-limit Device Try-group analysis-method analysis-uncertainty (percent of the action-limit) Note Aluminum 0.2 mg/l A or B 25 is in the trial Group A in cases where aluminum is used as a water treatment chemical. Is otherwise in the trial Group B.

Ammonium 0.50 mg/l A or B 40 is in the trial Group A in those cases where kloramin is used. Is otherwise in the trial Group B.

Clostridium perfringens (including spores) 0 number/100 ml B ISO 14189 Clostridium perfringens is only compulsory to analyze if the raw water is surface water, or is influenced by surface water. If the action limit is exceeded, to examine whether the owner vannverks pathogenic micro-organisms or parasites such as Cryptosporidium, are present.
Analysis method approved in accordance with regulation 12. April 2001 No. 1372 about water supply and drinking water may be used up to 30. June 2017.

Color No abnormal change A Norwegian food safety authority recommends that color the number does not exceed 20 mg/l Pt. See also annex 1.

Iron 0.2 mg/l A or B 30 is only in the trial Group A in cases where the iron is being used as a water treatment chemical. Is otherwise in the trial Group B.

Kim number 22 ° C 100 and no abnormal change quantity/ml A NS-EN ISO 6222 Chloride 250 mg/l B 15 water should not be corrosive.

Coliform bacteria 0 quantity/100 ml A NS-EN ISO 9308-1 or ISO 9308-2 analysis method approved in accordance with regulation 12. April 2001 No. 1372 about water supply and drinking water may be used up to 30. June 2017.

Conductivity 250 mS/m at 20 ° C A 20 water should not be corrosive.

Smell No abnormal change A see also Appendix 1.

Manganese 0.05 mg/l B 30 Sodium 200 mg/l B 15 pH 6.5-9.5 A 0.2 Analysis uncertainty is not in percentage of pH, but in pH units. The water should not be corrosive.

Taste No abnormal change A see also Appendix 1.

Sulfate 250 mg/l B 15 water should not be corrosive.

Total organic carbon (TOC) no abnormal change B CEN 1484 30 measurement of uncertainty analysis shall be estimated at 3 mg/l of the TOC.

Turbidity No abnormal change A NS-EN ISO 7027 30 Norwegian food safety authority recommends that turbiditeten out from the water treatment plant does not exceed 1 NTU by water supply systems that use surface water. The poll of analysis uncertainty is estimated at 1 NTU. See also Appendix 1.

Appendix 3 application for approval of water treatment chemicals should contain the following documentation: a) information about the applicant contact information b) product's trade name c) name of manufacturer information d) and highest dosage e) information about the chemical composition that involves a complete list of all components with CAS-number and percent amount in the product to 100 percent and f) certificate of analysis for all of the components.
