ASTM deviations to ISO 10079-3: 1999 2 Normative refer

8、ences (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 10079-3 5.2 Suction tubing (Add the following) Suction tubing supplied with the su

9、ction equipment shall have a minimum length of 1.3 m. Rationale for ASTM deviation: This minimum length is specified in ISO 10079-1and 10079-2 8 Performance requirements for vacuum and flow rate (Replace the following clauses and delete Subclauses 8.5 and 8.6) 8.2 Vacuum When tested in accordance wi

10、th A.12, suction equipment shall develop a vacuum of at least 40 kPa, unless either marked “low vacuum” or marked with the maximum vacuum that can be developed. 8.3 Free Air Flow When tested in accordance with A.14, the peak free air flow shall be at least 20 L/min unless marked “low flow” in which

11、case the peak air flow shall be less than 20 L/min. Equipment intended for thoracic drainage, wound drainage, and intermittent and interrupted suction shall be exempt from the requirements of this clause. Rationale for ASTM deviation: This simplifies performance categories and allows all combination

12、s of high and flow vacuum and flow but exempts application-specific apparatus such as thoracic suction equipment. 10 Regulators (Add the following) 10.3 Intermittent Regulators 10.3.1 Intermittent Regulator Function When tested in accordance with A.19, an intermittent regulator shall cycle through i

13、ts off-time according to the manufacturers published specifications. 10.3.2 Intermittent Regulator Venting When tested in accordance with A.20, an intermittent regulator shall return to atmospheric pressure (0-kPa gauge) for at least 3 s before commencing the next on-cycle. 10.4 Interrupted Regulato

14、rs 10.4.1 Interrupted Regulator Function When tested in accordance with A.21, an interrupted regulator shall cycle between the vacuum relief set point and that of a lower level according to the manufacturers published specification. 10.4.2 Interrupted Regulator Venting When tested in accordance with

15、 A.22, an interrupted regulator shall return to a lower vacuum level before returning to the vacuum relief set point. Rationale for ASTM deviations: Above requirements can be found in CGA Z16811-94 but not ISO 10079-3 12.2 Equipment on carrying case (Change title to the following) Equipment or carry

16、ing case Rationale for ASTM deviation: Typing error in ISO document. (Replace a) with the following) a) the performance category as indicated in Clause 8 or the vacuum and flow rate ranges for patient use, with the marking visible in the normal operating position; Rationale for ASTM deviation: To ma

17、ke the marking consistent with performance. 13 Information to be supplied by manufacturer (Add the following) k) whether or not the suction equipment is suitable for use in a magnetic resonance imaging (MRI) unit. Rationale for ASTM deviation: This knowledge is necessary for safe use. Annex A Test m

18、ethods A.14 Test for free air flowrate of low vacuum equipment (Change title and test as follows) A.14 Test for free air flow With the collection container(s) empty, switch on the suction equipment with the regulator adjusted to give the maximum vacuum. Open the inlet and attach a low resistance flo

19、wmeter to it. Note the mean free air flow when stable conditions are reached. Rationale for ASTM deviation: To make the test procedure consistent with performance modifications. Vacuum level is tested in A.12. Therefore A.14 only needs to test for free air flow. A.17 Test for vacuum regulator with v

20、ariable setting (Modify as follows) Commence with the vacuum source at 79 kPa below atmospheric pressure and reduce the vacuum to 53 kPa below atmospheric pressure adjust the vacuum source from 53 kPa to 80 kPa below atmospheric pressure Rationale for ASTM deviation: Source pressure of 53 kPa is nee

21、ded in order to set the regulator to 53 kPa as required in test procedure. CGA Z168.11-94 also uses a supply pressure of 53 kPa for this test. Annex A (Add the following) A.19 Test for intermittent function of intermittent regulators (See Figure A.10) Connect the regulator to a vacuum source as reco

22、mmended by the manufacturer. Set the regulator to the intermittent mode and occlude the tubing at the patient port. Set the occluded vacuum level to a point in the middle third of the gauge range during the on cycle. With the unit still occluded, record the on time and off time during five full cycl

23、es. A.20 Test for venting of intermittent regulators (See figure A.11) Connect the regulator to a vacuum source as recommended by the manufacturer. Connect the patient side of the regulator to the vacuum side of a 2-L collection container. Occlude the patient side of the regulator. Set the regulator

24、 to the intermittent mode, occlude the tubing between the regulator and the collection container, and adjust the regulator to a point in the middle third of the gauge range during the on cycle. Release the occlusion on the tubing, ensuring that the regulator is cycling normally, and record the amoun

25、t of time that the vacuum indicator is at 0-kPa gauge (atmospheric pressure) during the off cycle. A.21 Test for interrupted function of interrupted regulators (See figure A.12) A.21.1 Fixed vacuum relief valves Connect the regulator to a vacuum source as recommended by the manufacturer. Adjust the

26、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 maximum vacuum obtained. A.21.2 Adjustable vacuum relief valves Connect the regulator to a vacuum source as recommended by the manufacturer. Adjust the r

27、egulator static set point to 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 maximum vacuum obtained. Repeat for the maximum vacuum relief valve set point. A.22 Test for venting of interrupted regulators A.22.1 Fixed vacuu

28、m relief valves 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. Connect a vacuum indicator having a range similar to that of the regulator to the patient side of the c

29、ollection container. 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 for five full cycles and record the minimum vacuum level on the 2-L collection container. A.22.2 Adjustable vacuum relief valves Connect

30、 the regulator to a vacuum source as recommended by the manufacturer. Connect a vacuum indicator having a range similar to that of the regulator to the patient side of the collection container. The patient side of the collection container shall have a vacuum indicator having a range similar to that

31、of the regulator. Adjust the regulator static set point to 2.7 0.2 kPa (20 mmHg) above the minimum vacuum relief valve set point. Allow the regulator to cycle for five full cycles and record the minimum vacuum level on the 2-L collection container. Repeat for the maximum vacuum relief set point. Rat

32、ionale for ASTM deviation: The additional test methods are needed for additional requirements. Test procedures were taken from CGA Z168.11-94.
