ASTM Deviations to ISO 10079-1: 1999 2 Normative refere
8、nces (Add the following) CGA Z168.11-94, Vacuum Devices Used for Suction and Drainage Rationale for ASTM deviation: CGA Z168.11-94 has requirements for intermittent and interrupted regulators that are not part of ISO 10079-1. 3 Terms and Definitions (Add the following) interrupted suction suction in
9、 which the negative pressure is automatically and periodically relieved to a lower negative pressure (for example, from -50 kPa to -5 kPa). single-fault condition condition in which a single means of protection against a hazard in equipment is defective or a single external abnormal condition is pre
10、sent Rationale for ASTM deviation: These definitions are needed because the terms are used in the documents. 6 Identification, marking and documents (Add the following to 6.8.2) 16) The manufacturer shall disclose whether or not the suction equipment is suitable for use in a magnetic resonance imagi
11、ng (MRI) unit. Rationale for ASTM deviation: This knowledge is necessary for safe use. 16.3 Components and general assembly (Make changes to the following subclauses) 56.5 (Add the following) 3) An intermittent regulator shall cycle through its off-time and on-time in accordance with the manufacture
12、rs specifications. Compliance shall be checked with the following test: Connect the regulator to a vacuum source as recommended by the manufacturer. Set the regulator to the intermittent mode and occlude the intermittent tubing. Set the vacuum to a level in the middle third of the gauge range during
13、 the on cycle. Record the on time and off time during five full cycles. 4) An intermittent regulator shall return to atmospheric pressure during the off-time for at least 3 s before commencing the next on-cycle. Compliance shall be checked with the following test: Connect the regulator to a vacuum s
14、ource as recommended by the manufacturer. Connect the patient side of the regulator to the vacuum end of a 2-L collection container. Occlude the patient side of the collection container with a pressure indicator having a range similar to that of the intermittent regulator. Set the intermittent regul
15、ator to the intermittent mode, occlude the intermediate tubing between the intermittent regulator and the collection container, and adjust the vacuum on the regulator to a level in the middle third of the gauge range. Release the occlusion on the intermittent tubing, ensure that the intermittent reg
16、ulator is cycling normally, and record the amount of time that the vacuum indicator indicates 0 kPa during the off cycle. 5) An interrupted regulator shall cycle between the set vacuum and a less negative vacuum in accordance with the manufacturers specifications. Compliance shall be checked with th
17、e following tests: a) Fixed vacuum relief Connect the regulator to a vacuum source as recommended by the manufacturer. Adjust the regulator to a vacuum 2.7 kPa more negative than the vacuum relief pressure. Allow the regulator to cycle through five full cycles and record the maximum and minimum pres
18、sures shown on the gauge and the times that these pressures are maintained. b) Adjustable vacuum relief Connect the regulator to a vacuum source as recommended by the manufacturer. Adjust the regulator to a vacuum 2.7 kPa more negative than the minimum vacuum relief pressure. Allow the regulator to
19、cycle through five full cycles and record the maximum and minimum pressures shown on the gauge and the times these pressures are maintained. Adjust the regulator to a vacuum of 2.7 kPa more negative than the maximum vacuum relief pressure. Allow the regulator to cycle through five full cycles and re
20、cord the maximum and minimum pressures on the gauge and the times these pressures are maintained. 6) An interrupted regulator shall return to a lower vacuum level before returning to the vacuum relief valve set point. Compliance shall be checked with the following tests: a) Fixed vacuum relief valve
21、s Connect the regulator to a vacuum source as recommended by the manufacturer. Connect the patient side of the interrupted regulator to the vacuum side of a 2-L collection container. The patient side of the collection container shall have a vacuum indicator having a range similar to that of the regu
22、lator. Adjust the regulator static set point to 2.7 0.2 kPa (20 mmHg) above the vacuum relief valve set point. Allow the vacuum relief valve to cycle and record the minimum vacuum level on the 2-L collection container. b) Adjustable vacuum relief valves Connect the regulator to a vacuum source as re
23、commended by the manufacturer. Connect the patient side of the interrupted regulator to the vacuum side of a 2-L collection container. The patient side of the collection container shall have a vacuum indicator having a range similar to that of the regulator. Adjust the regulator static set point to
24、2.7 0.2 kPa (20 mmHg) above the minimum vacuum relief valve set point. Allow the vacuum relief valve to cycle and record the minimum vacuum level on the 2-L collection container. Repeat for the maximum vacuum relief set point. Rationale for ASTM deviations: Above requirements can be found in CGA Z16
25、8.11-94 but not ISO 10079-1 56.12 Inlet port of collection container (Remove the following note) Note 1 Suction performance may be markedly affected by the length and diameter of the suction tubing. An indication of the magnitude of this affect is in Annex P. Rationale for ASTM deviation: Note 1 in
26、the ISO standard relates to suction tubing, not the collection container and the annex is incorrectly identified. 56.13 Suction tubing (Add the following at the beginning) The internal diameter of the suction tubing shall not be less than 6 mm. Rationale for ASTM deviation: Since suction performance
27、 may be affected by the diameter of the tubing, that diameter should be specified. This is the minimum diameter specified in ISO 10079-3. (Add the following) Note: Suction performance may be markedly affected by the length and diameter of the suction tubing. An indication of the magnitude of this ef
28、fect is given in Annex O. Rationale for ASTM deviation: This note, which is part of 56.12 in the ISO 10079-1 standard, belongs here.

34、nternational Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee ha
35、s been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical sta
36、ndardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard requires approval by at leas
37、t 75 % of the member bodies casting a vote.International Standard ISO 10079-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic andrespiratory equipment, Subcommittee SC 8, Suction devices for hospital and emergency care use.This second edition cancels and replaces the first edition (ISO 1
38、0079-1:1991), which has been technically revised.ISO 10079 consists of the following parts, under the general title Medical suction equipment: Part 1: Electrically powered suction equipment Safety requirements Part 2: Manually powered suction equipment Part 3: Suction equipment powered from vacuum o
