DIN EN ISO 11114-3-2011 气瓶.气瓶和瓶阀材料与盛装气体的相容性.第3部分:氧气环境中非金属材料的自燃试验(ISO 11114-3-2010);德文版本EN ISO 11114-3-2010
Gas cylinders - Compatibility of cylinder and valve materials with gas contents - Part 3: Autogenous ignition test for non-metallic materials in oxygen atmosphere (ISO 11114-3:2010); German version EN ISO 11114-3:2010
This part of ISO 11114 specifies a test method to determine the autogenous ignition temperature of non metallic materials in pressurized gaseous oxygen.
The autogenous ignition temperature is one of the criteria for ranking materials, and can be used to assist with the choice of materials used in the presence of gaseous oxygen.
It is intended that this part of ISO 11114 be used for the selection of non-metallic materials for gas cylinders and accessories, for example to select the materials in order to meet the requirement for type testing for oxygen compatibility of all cylinder valves for highly oxidizing gases as specified in ISO 10297.
