7、ionThis British Standard supersedes BS 5682:1998, which is withdrawn.Information about this documentThis is a full revision of the standard, which takes account of productdevelopment and changes in products since the last edition. Its principal changesare:a) introduction of dimensions for probes and

8、 terminal outlets forhelium/oxygen mixtures;b) specifications for the dimensions of the terminal outlets for all specifiedmedical gases.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are expressed in sentences in which the princi

9、pal auxiliary verb is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Requirements in this standard are drafted in accordance with Rules for thestructure and drafting of UK standards, subclause J.1.1, whi

10、ch states,“Requirements should be expressed using wording such as: When tested asdescribed in Annex A, the product shall .”. This means that only those productsthat are capable of passing the specified test will be deemed to conform to thisstandard.Contractual and legal considerationsThis publicatio

Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligationsBS 5682:2015 BRITISH STANDARD1 ScopeThis British Standard specifies dimensions for probes and term

12、inal units for thesupply of medical gases (including vacuum).It is applicable to probes and terminal units for the following medical gases: oxygen; nitrous oxide; oxygen/nitrous oxide mixture; medical air 400 kPa; medical air 700 kPa and above; helium/oxygen mixture; and vacuum.This standard does no

13、t include specifications for probes and terminal units for: nitrogen for driving surgical tools; carbon dioxide; or oxygen 93.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdocument and are indispensable for its application.

19、0-1:2008, 3.154 General requirementsThe safety, materials, design and construction of the probes and terminal unitsshall be in accordance with BS EN ISO 9170-1.5 Probes5.1 The probes shall conform to the dimensions detailed in Figure 1, and Table1. The shoulder of the probe-indexing collar shall hav

20、e a diameter no greaterthan diameter A and shall not extend beyond 46 mm from the tip of the probe.NOTE The restriction on the distance from the tip of the probe to the shoulderof the probe indexing collar is to allow access to the mechanism for releasing theprobe from the terminal unit when install

21、ed.5.2 Remote probes shall be provided with a probe insert to suit the appropriatehose as specified in BS EN ISO 5359.5.3 Direct probes shall be either an integral part of a medical device, notintended to be dismantled by the user, or shall incorporate the body of theappropriate non-interchangeable

22、screw-threaded (NIST) connector as specified inBS EN ISO 18082.5.4 The coupling between a direct probe and a medical device shall permitaccess to the probe release mechanism on the terminal units.NOTE See note to 5.1.5.5 With the exception of the locating slot, the gas-specific indexing collar ofthe

23、 Probe shall be a fully formed annulus.5.6 The gas-specific indexing collar and probe shall be machined or formed froma single piece in order to maintain the concentricity of the component, i.e. thecollar shall not be comprised of a separately manufactured component.5.7 The material used for probes

24、shall have a minimum hardness value of 120HBW 2.5/62.5 when tested in accordance with BS EN ISO 6506-1.NOTE 1 The mechanical properties of the probes are specified to minimize the riskof cross-connection in conditions of normal use and reasonably foreseeable misuse.NOTE 2 Hardness equivalence tables

25、 are provided in BS EN ISO 6506-4.NOTE 3 Stainless steels and nickel or chromium plated brasses are consideredsuitable hardwearing materials for probes.BRITISH STANDARDBS 5682:20152 The British Standards Institution 2015Figure 1 Probe dimensionsNOTE 1 All dimensions in millimetresNOTE 2 Surface fini

32、vices fitted with a directprobe shall include a non-removable anti-swivel device to locate the probelocating slot and maintain the vertical orientation of the device directly attachedto the probe.

34、orporate a direct probe, which has a locating slot that corresponds witha locating pin in the terminal unit to prevent the device from rotating. This meansof preventing rotation is unnecessary in terminal outlets for any gases that do notrequire a flow device or that are not mounted vertically, as i

Hence the option to not install thepins.6.6 The terminal unit indexing annulus shall be manufactured from a materialwith mechanical properties to meet the requirements of the force test (see 6.2).6.7 The probe retaining mechanism sha
