This document specifies the requirements and test methods applicable to factory applied external polyurethane based coatings for heavy duty (see EN 545:2010, Clause D.3) corrosion protection of buried ductile iron pipes in accordance with EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C. This document is not applicable to ductile iron pipes protected with zinc with a finishing layer of polyurethane. This document is not applicable to special activities on site such as tapping, clamping, etc., which could affect the corrosion protection properties of the polyurethane coating. NOTE These operations are usually specified in the laying instructions supplied by manufacturers of clamps, house connection saddles, etc. and any relevant user procedures.

This document defines terms relating to data quality. These terms are used by the parts in the ISO 8000 series.

This document specifies machinery safety requirements. This document is applicable to thermal and catalytic cleaning systems with regenerative or recuperative preheating for exhaust gas loaded with flammable substances from surface treatment equipment. This document deals with all significant hazards, hazardous situations or hazardous events relevant to thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment, when these are used as intended and under conditions of misuse which are reasonably foreseeable. See Annex A for significant hazards. The specific significant risks related to the use of this machinery with exhaust gases from sources other than surface treatment equipment (e.g. from chemical production, tank farms, cremation, wastewater treatment) are not dealt with in this document. Limits of thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment are specified by the interfaces given in Figure 1. Figure 1 - Limits of the machinery This document is not applicable to - cleaning systems without preheating of input gas; - cleaning systems for input gas with a concentration of flammable substances higher than those specified in 4.8; - cleaning systems for input gas containing H2 or pyrolysis gases; - cleaning systems for input gas with a O2/N2 ratio higher than in air; - absorptive and adsorptive exhaust gas cleaning systems; - membrane separators; - UV exhaust gas cleaning systems; - filter systems; - plasma exhaust gas cleaning systems; - biological exhaust gas cleaning systems. This document is not applicable to the machinery or machinery components manufactured before the date of its publication.
