EN 739:1998 BSI 16 October 2002 3 Introduction This European Standard has been prepared in response to the need for a safe method of connecting medical equipment to a fixed medical gas pipeline system or other medical gas supply system suc
34、h that hose assemblies carrying different gases, or the same gas at different pressures, cannot be interchanged. Fixed medical gas pipelines once installed are rarely disturbed and are subjected to commissioning procedures to avoid the possibility of cross-connections or contamination of the medical
35、 gas conveyed. However, hose assemblies are subjected to physical wear and tear, misuse and abuse throughout their relatively short service life and are frequently connected to, and disconnected from, the medical equipment and the fixed pipeline. While recognizing that no system is absolutely safe,
36、this standard includes those requirements considered necessary to prevent foreseeable hazards arising from the use of hose assemblies. Operators should be continually alert to the possibility of damage being caused by external factors and it is therefore essential that regular inspection and repair
37、is undertaken to ensure that hose assemblies continue to meet the requirements of this European Standard. This European standard pays particular attention to: suitability of materials; gas-specificity; cleanliness; testing; identification; information supplied. Rationales for some of the requirement
38、s of this European Standard are given in Annex B. Such requirements are indicated by the letter R after the clause number. 1 Scope 1.1 This European Standard specifies requirements for low-pressure hose assemblies intended for use with the following medical gases: oxygen; nitrous oxide; air for brea
39、thing; helium; carbon dioxide; xenon; ? NO/N2 mixtures (NO ? 1 000 ?l/l);? specified mixtures of the gases listed above; air for driving surgical tools; nitrogen for driving surgical tools; vacuum. It is intended especially to ensure gas-specificity and to prevent cross-connection between different
40、gases. These hose assemblies are intended to be used in the pressure range between 300 kPa and 1 400 kPa for compressed medical gases and between 10 kPa and 100 kPa absolute pressure for vacuum. 1.2 This European Standard does not specify the intended uses of hose assemblies. Some examples of the in
41、tended uses specified in other standards are as follows: a) between a terminal unit and medical equipment (see EN 737-1, prEN 740, EN 794-1); b) between the fixed pipeline system and a terminal unit of that system (prEN 737-3, EN 793); c) between a terminal unit and a second terminal unit (see prEN
42、737-3); d) between an emergency supply and an emergency and maintenance inlet point of a pipeline system (see EN 738-1, prEN 737-3); e) between an emergency supply and medical equipment (see EN 738-1, prEN 740, EN 794-1).
