19、RNING Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure complia
20、nce with any national regulatory conditions. 1 Scope This Technical Specification specifies the requirements for flexible thermoplastic polyurethane tubing conveying compressed air, for use in the ambient temperature range from 23 C to 60 C, in sizes from 3 mm to 12 mm outside diameter. Working pres
21、sure depends on the tube size and the service temperature (see Table 4). Tubing may be used with push on connectors which are specified in ISO 14743. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applica
22、tion. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

25、ane and shall be homogenous, and free from surface imperfections. The tubing is extruded and can be coloured to user requirements. For applications where there is moisture or water present above 40 C, polyurethane materials with good hydrolysis resistance would be required. This must be specified by
26、 the user to the supplier of the tubing. 5 Dimensions and tolerances 5.1 Outside diameters, wall thickness and tolerances The outside diameters and tolerances of tubing shall meet the requirements given in Table 1.
