CLAUSE 20 REQUIREMENTS Add the following variation: This clause is made VOID. In Australia and New Zealand tests of resistance of fire are carried out according to 21. REMARKS VERDICT P 21 21.1 After 20 add the following variation: 21 Resistance to Fire Parts of non-metallic material shall be resistant to ignition and spread of fire. This requirement does not apply to decorative trims, knobs and other parts unlikely to be ignited or to propagate flames originating from inside the apparatus, or the following: (a) Components that are contained in an enclosure having a flammability category of FV-0 according to AS/NZS 4695.707 and having openings only for the connecting wires filling the openings completely, and for ventilation not exceeding 1mm in width regardless of length. Small mechanical parts, the mass of which does not exceed 4g, such as mounting parts, gears, cams, belts and bearings; Small electrical components, such as capacitors with a volume not exceeding 1 750mm3, integrated circuits, transistors and optocoupler packages, if these components are mounted on material of flammability Category FV-1 or better according to AS/NZS 4695.707. P 1. Fire enclosure used. 2. No fire enclosure. P N (b) The following parts which would contribute negligible fuel to a fire: - - P NOTE: In considering how to minimize propagation of fire and what \"small parts\" are, account should be taken of the cumulative effect of small parts adjacent to each other for the possible effect of propagating fire from one part to another. Compliance is checked by tests of 21.1.1 and 21.1.2. For the base material of PRINTED BOARDS compliance is checked by the test of 21.1.3 The tests are carried out on parts of non-metallic material which have been removed from the apparatus. When the glow-wire test is carried out, they are placed in the same orientation as they would be in normal use. These tests are not carried out on internal wiring 1. Not tested (V-1 min). 2.

Parts tested at 750C. VERDICT N P P N Parts for which the glow-wire test cannot be carried out, such as those made of soft or foamy material, shall meet the requirements specified in ISO 9772 for Category FH-3 material. The glow-wire test is not carried out on parts of material classified at least FH-3 according to ISO 9772 provided that the sample tested was not thicker than the relevant part. N P N 21.1.2 Part of insulating material supporting POTENTIAL IGNITION SOURCES are subject to the glow-wire test of AS/NZS 4695.2.11 which is carried out at 750°C. The test is also carried out on other parts of insulating material which are within a distance of 3mm of the connection. NOTE: Contacts in components such as switch contacts are considered to be connections. The test is not applicable to parts supporting welded connections N P 1. No parts inside 20 by 50mm cylinder. 2. No flaming on 750°C test. The needle-flame test is made in accordance with AS/NZS 4695.2.2 with 3. Parts tested with needle flame ______ the following modifications: 4. Parts inside cylinder 5 Severities rated V-1/_____mm. Replacements: For parts which withstand the glow-wire test but produce a flame, other parts above the connection within the envelope of a vertical cylinder having a diameter of 20mm and a height of 50mm are subjected to the needle-flame test. However, parts shielded by a barrier which meets the needle-flame test are not tested. The duration of application of the test flame is 30s  1s. 8 Test Procedure 8.2 Modification: The specimen is arranged so that the flame can be applied to a vertical or horizontal edge as shown in the examples of figure 1. 8.4 Modification: The fist paragraph does not apply. Addition: If possible, the flame is applied at least 10mm from a corner 8.5 Replacement: The test is made on one specimen. If the specimen does not withstand the test, the test may be repeated on two further specimens, both of which shall then withstand the test. N N P P P

CLAUSE 21.1.2 (Cont'd) REQUIREMENTS 10 Evaluation of test results The duration of burning (tb) shall not exceed 30s. however, for PRINTED BOARDS, it hall not exceed 15s. The needle-flame test is not carried out on parts of material classified as V-0 or V-1 according to IEC 60695-11-10 provided that the sample tested was not thicker than the relevant part. If parts, other than enclosures, do not withstand the glow wire tests of 21.1.2, by failure to extinguish within 30s after the removal of the glow-wire tip, the needle-flame test detailed in 21.1.2 is made on all parts of non-metallic material which are within a distance of 50mm or which are likely to be impinged upon by flame during the tests of 21.1.2. parts shielded by a separate barrier which meets the needle-flame test are not tested. NOTE: If the enclosure does not withstand the glow-wire test the appliance is considered to have failed to meet the requirement of Clause 21 without the need for consequential testing. NOTE: if other parts do not withstand the glow-wire test due to ignition of the tissue paper and if this indicates that burning or glowing particles can fall onto an external surface underneath the apparatus, the apparatus is considered to have failed to meet the requirement of Clause 21 without the need for consequential testing. NOTE: Parts likely to be impinged upon by the flame are considered to be those within the envelope of a vertical cylinder having a radius of 10mm and a height equal to the height of the flame, positioned above the point of the material supporting in contact with or in close proximity to connections.

Barrier used, rated V-1/_____mm N N P P 21.2 The base material of PRINTED BOARDS is subjected to the needle-flame test of Clause 21.1.2. the flame is applied to the edge of the board where the heat sink effect is lowest when the board is positioned as normal use. The flame shall not be applied to an edge consisting of broken perforations, unless the edge is less than 3mm from a POTENTIAL IGNITION SOURCE. The test is not carried out if the: - - PRINTED BOARD does not carry any POTENTIAL IGNITION SOURCE.
