35、tandard regarding the product quality of enamelled valves and pressure pipe fittings for untreated and potable water supply take into account the real stress conditions to which a component can be subjected in the course of its operating life. Typical types of stress are: during storage: climate, UV
36、 radiation, mechanical stress; during transportation: mechanical stress e.g. at certain points (impact), laterally (friction); during preparation for installation: cleaning agents, mechanical stress e.g. at certain points (impact), laterally (friction); during installation: mechanical stress; during
37、 operation: abrasion caused by the carried medium, corrosion from surrounding medium, mechanical stress from shifting ground loads, UV radiation with valves built in above ground.EN ISO 11177:2016 (E) DIN EN ISO 11177:2016-105 1 ScopeThis International Standard specifies the requirements for product
