1 Scope This Standard specifies terms and definitions, classification and designation, requirements, test methods, rest rules, marking, labeling, packaging, transportation and storage of polytetrafluoroethylene bellows compensators (hereafter referred to as compensators). This Standard is applicable to the compensators using polytetrafluoroethylene as the overflowing position for the purpose of flexible compensation action for the pipelines, with nominal pressure PN not greater than 1.6 MPa, nominal dimension of DN25 mm~1000 mm, and operating temperature of -50℃~180℃, under the media of various concentrations, e.g. sulfuric acid, hydrochloric acid, hydrofluoric acid, benzene, alkali, aqua regia, organic solvent, reductant, and strongly-corrosive gas and liquid. This Standard is not applicable to the compensators under such media as fused alkali, sodium metal, potassium, chlorine trifluoride and gaseous fluorine. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, the parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards. For undated references, the latest edition of the normative document referred to applies.
