42 Tests on Liquid Containers
42.1 Where the deterioration of a liquid container seal, or similar component results in a risk of fire or
injury to persons, the container seal, or similar component shall be resistant, as determined by
investigation, to deterioration from the liquid intended to be in contact with the container seal.
42.2 To determine compliance with 42.1, the component shall be investigated with respect to the material
of which the component is made, the size and shape of the component, the application in the appliance,
and other factors. Where applicable, the investigation shall include visual inspection for cracks,
deformation, and similar damage or deterioration after artificial aging, as well as comparison of hardness,
tensile strength, and elongation before and after artificial aging.
42.3 With reference to 42.1 and 42.2, a component of rubber or neoprene, when tested to compare its
tensile strength and elongation before and after artificial aging, complies when these properties are found
to be not less than the minimum values specified in Table 42.1, corresponding to the temperature on the
component during the Temperature Test, Section 37.

43 Burnout Test on Components
43.1 General
43.1.1 With reference to 6.7, an unenclosed relay, a solenoid, or similar component, including a solenoid
valve and a motor-starting relay, shall not emit flame or molten metal, other than solder, nor shall it result
in glowing or flaming of the cheesecloth or tissue paper when tested as described in 43.1.2.
43.1.2 To determine whether a device complies with the requirement in 43.1.1, the device is to be
supported on a soft wood surface covered with a double layer of white tissue paper, and is to be covered
with a double layer of white cheesecloth. The device is to be energized as specified in 32.1. The test is
to be continued for 7 hours unless burnout occurs sooner; or for a construction where the component is
positively and reliably controlled by an automatic timer, protector, or similar device so that operation of the
component is limited to a shorter interval, the test is to be terminated at the conclusion of such interval.
The supply circuit is to include a fuse of the maximum current rating that is accommodated by the
