according to IEC 60335-1 / 2006-09 § 11.2 and § 11.3
S t a n d a r d O u t f i t :
1 plywood board, 20 -2 mm thick, with frame on all sides and with covering board at the lower
side, together approx. 150 mm thick, with 4 feet, size and layout to allow the completition to a
test corner,
1 set of measuring points, consisting of:
copper disks, diameter 15 mm, 1 mm
thick, embedded at distances of 50
mm x 50 mm in the plywood board,
their front flush with the surface of the
plywood board,
and fine-wire thermocouples nickelchromium-
nickel (NiCr-Ni), soldered to
the back of the copper disks, thermoelectric
wires with a diameter of 0,3 -0,1
mm, insulated with glass-silk or similar
temperature resistant material,
1 set of change-over switches to select the lines resp. rows of the copper disks, to connect the
selected copper disk with the socket-outlet and the temperature indicating instrument,
1 socket-outlet, two-pole, almost without thermoelectric voltage, plug with cable of nickelchromium-
nickel, length 1.5 m, for the connection of a external measuring instrument,
1 temperature indicating instrument, supplied by battery, and switch to select instrument or
socket-outlet.
Des ign: plywood board, frame and copper disks
painted dull black, copper disk lines and rows
marked.
Most PTL Temperature Measuring Boards are tailormade,
the following Article Nos are examples.
