Product description
Product Name: Black Transparent Electromagnetic Oven panel
Guangdong Kedi Glass-ceramic Industrial Co., Ltd.
1 Scope of Application
This manual applies to black transparent glass ceramics panel.
2 Reference Standard
Guangdong Province Industry Standard, Q/PKT 02-2007
Broad Black Transparent Glass-ceramic Plate.
3 Material
Black
transparent
glass
ceramics
are
used
to
meet
the
special
requirements of electromagnetic oven
Standard features which are to be described respectively, fit the RoHS
rules.
3.1 Characteristics of glass ceramics
3.1.1 Maximum Service Temperature:
The
original
color
of
the
plate
will
change
at
the
temperature
of
780 ℃.

3.1.2 Temperature of Thermal Shock
780
℃
(thermal
shock
resistance test: after
heating
the
electric
furnace and keeping the temperature at 780
℃
, place the plate in it for 30
minutes,
the
characteristics
of
the
plate
keeps
stable
when
it
is
immediately thrown into the water).
4 Specifications
4.1 The size and shape of the electromagnetic stove panel are subject to
the requirement diagram.
4.2
Dimensions
and
test
method
of
the
product
are
measured
in
accordance with the design and the Vernier caliper.

4.3 The amount of deformation is within 1.0mm (in the process of testing,
the product should be placed on the horizontal platform, and measured
by a plug gauge coordinated a standard ruler. Only ruler is allowed to be
place on the plate.)
4.4 The allowance error of thickness is within
±
0.5mm.
4.5 The allowance error of the straight edge is within
±
0.5mm. The arc
edge is smooth, without broken and flanging edge.
4.6 The R angle of product is within
±
0.3mm. The perpendicularity and
parallelism is presented in Figure 1.

a or a
’ should be within 1mm:

b or
b’ should be within 1mm:

Edge c should be alongside with the right angle.

5 The Specification of Shape
5.1 Panel: bright and uniform color without apparent sand inclusion,
scratch, blot or edge broken.
5.2 Screen-printing: the pattern and color are in accordance with the
design for the customer.
