(1) An appliance shall be in such a condition that when it is in normal use–
(a) all its gas-carrying components are sufficiently sound to prevent any likelihood of death or personal injury arising from the escape of gas;
(b) the door of any oven comprised in the appliance is sealed in such a manner as to prevent the escape of the products of combustion in such quantity as to give rise to any likelihood of death or personal injury;
(c) any device forming part of the appliance designed to ignite any burner operates so as to ensure the prompt ignition of the burner;
(d) the ignition of any burner by an automatic or manual device results in the cross-lighting to all flame ports in the burner;
(e) the stability of the flame from any burner after a period of more than one minute after ignition is such as to ensure that the base of the flame does not move away, either in whole or in part, from the burner port and the flame does not return inside the body of the burner;
(f) the quantity of carbon monoxide in the products of combustion is not such as to give rise to any likelihood of death or personal injury;
(g) any device which is designed to shut off the supply of gas to any burner when the flame is unintentionally extinguished, operates to ensure that the supply of gas intended to be controlled by the device is promptly and safely shut off;
(h) in the case of an appliance fitted with a burner the ignition of which can take place in a closed compartment with the door closed, the gas rate to any such burner which is not controlled by a flame supervision device does not exceed 600 watts;
(i) in the case of an appliance fitted with a shut down lid, any device which is designed to shut off automatically the supply of gas to every burner comprised in the hot-plate when the lid is shut down operates to ensure that the supply of gas intended to be controlled by the device is promptly and safely shut off;
(j) the surface temperature of any parts of the appliance other than working surfaces and any part of a surface which is adjacent to–
(i) any part of any hob unit; or
(ii) a working surface of the appliance or the periphery of any oven vent or any other aperture necessary for the functioning of the appliance,
is not such as to give rise to any likelihood of death or personal injury through incidental contact with any part of the appliance or through contact with those parts of the appliance intended to be touched when it is in normal use.
(k) the heat emitted by the appliance is not such as to cause any adjacent walls, floors or materials to reach a temperature giving rise to any likelihood of a fire hazard or personal injury;
(l) in the case of an appliance fitted with any lids, oven doors, splash-backs or other components comprised wholly or partly of glass, the type of glass employed, its thickness and its size are such as to prevent the breakage of the glass giving rise to any likelihood of death or personal injury;
(m) all accessible parts of the appliance are free from sharp edges;
(n) in the case of an appliance designed to stand unsecured on a floor, table or other level surface, the appliance is stable when the oven doors and grill doors are open and when a load of 15 kg is placed at the centre of the oven door where an oven drop door is fitted or is placed at the centre of the top edge of the door where an oven door with a vertical axis is fitted;
(o) any pan support comprised in the appliance is such as to ensure the stability of any cooking vessels designed to be placed upon it;
(p) any tap handle of the appliance is so designed as to ensure that it is not liable to be turned on accidentally and is otherwise capable of easy operation; and
(q) any variation which might reasonably be expected in the rate, pressure or composition of the gas supply or a failure of, or any subsequent restoration of, any electrical or other source of energy which is auxiliary to the gas supply is not such as to give rise to any likelihood of death or personal injury.
(2) An appliance shall be in such a condition that the characteristics of the appliance required to comply with paragraph (1) above will not be altered in the course of the normal use of the appliance, whether through the distortion or deterioration of any materials used in its construction or through the accidental displacement of any components comprised in the appliance.
