Any other downward facing combustible surface less than 600 mm
above the highest part of the hob shall be protected for the full width
and depth of the cooking surface area in accordance with Clause
5.12.1.2. However, in no case shall this clearance to any surface be
less than 450 mm.
2 Side clearances – (Measurements B & C)

vertical combustible surface, is less than 200 mm, the surface shall
be protected in accordance with Clause 5.12.1.2 to a height C of not
less than 150 mm above the hob for the full dimension (width or

NOTES
1 Requirement 3 does not apply to a freestanding or elevated
cooking appliance which is designed to prevent flames or the
cooking vessels from extending beyond the periphery of the
appliance.
2 The ‘cooking surface area’ is defined as that part of the
appliance where cooking normally takes place and does not
include those parts of the appliance containing control knobs.
3 For definition of hob, see Clause 1.4.64.
4 For definition of trivet, see Clause 1.4.109.
