AAMI ST15883-3 pdf free download.Washer-disinfectors- Part 3: Requirements and tests for washer-disinfectors employing thermal disinfection for human waste containers.
4.3.2 When the container(s) are to be emptied automatically the emptying system shall ensure that there is no spillage of the container contents or discharge of aerosols of the contents of containers during automatic emptying.
Check for compliance in accordance with 6.5.1.
4.3.3 When the container(s) are to be emptied manually into the WD the door aperture and load support system shall be designed to enable the container to be emptied and then located in the load carrier without spillage or splashing.
Check for compliance in accordance with 6.5.2.
4.4 Cleaning
4.4.1 Flushing
The containers shall be flushed with sufficient water to remove the gross soiling.
NOTE The water used to flush the containers can be discharged without recirculation or be recirculated during a single flushing stage within one process cycle.
4.4.2 Washing
The containers shall be washed on both their inner and outer surfaces.
NOTE The water used to wash the containers can be discharged without recirculation or be recirculated during a single washing stage within one process cycle.
4.4.3 Test requirements
The cleaning process shall meet the requirements of the test specified in 6.6.
4.5 Disinfecting
4.5.1 Thermal disinfection shall be deemed to have been attained when all surfaces to be disinfected have been subjected to a process that has been demonstrated to provide the disinfection level claimed by the manufacturer. providing an A0 of at Iea6t 60.
4.5.2 When tested by the method specified in ISO 15883-1 ANSI/AAMI ST15883-1, 6.8.2, 6.8.3 and
6.8.4, the surface temperatures and times shall provide the specified A0 values. the appropriate disinfection level.
5.3 Venting, draining and purging
5.3.1 For free standing and single door WDs the drainage outlet shall be placed towards the rear of the
WD.
This should be done in such a manner that it is possible to make connection with a drainage outlet in any position within a horizontal angle of 1800.
5.3.2 When tested in accordance with 6.2, the water seal in the trap between the chamber and the drain shall not be broken during five consecutive operating cycles.
NOTE When it is not practicable to vent to the outside atmosphere, a condenser can be used for indirect venting. This can produce a backpressure which, if excessive, will break the water seal between the chamber and the drain. The test is intended to verify that this does not occur.
5.3.3 After the completion of the washing stage of the operating cycle, the trap shall be clear of soil and waste.
Compliance shall be tested in accordance with 6.3 and 6.4.
After each of five tests carried out in accordance with 6.3 there shall be no test spheres retained within the chamber or trap.
After each of five tests carried out in accordance with 6.4 there shall be no toilet tissues retained within the chamber and the trap shall be clear.
5.4 Water quality
The tests required by ISO ANSI/AAMI ST15883-1, 5.23.3 (see also ISO 15883 1 ANSI/AAMI ST15883-1, 6.4.2.2) shall be limited to determination of hardness (expressed as millimole per liter (mmol/l) of CaCO3) when the water is from a potable supply.
6 Testing for conformity
6.1 General
Testing for conformity shall be carried out in accordance with ISO 15883 1 ANSI/AAMI ST15883-1 Clause 6.
NOTE Annex A includes a summary of test programs for WDs for human waste containers in addition to those recommended in ISO 15883-1 ANSI/AAMI STI 5883-I, Annex A.
6.2 Test for drain seal integrity
Fit a transparent test trap of the same type and dimensions as that normally fitted to the WD in place of the normal trap and connect it to a suitable outlet.AAMI ST15883-3 pdf download.
