Test body is arranged to cladding material surface down, under the condition of 250 DEG C, leaves standstill 10 minutes, by visually observing coming off and offset thus carry out evaluating (carbonize thermal insulation layer formed before) of cladding material.
Evaluation criterion is as follows respectively.Result is as shown in table 1-1 ~ 1-3.
A: without coming off
B: a top layer part comes off
C: all come off
The cold and hot Cycle Assessment of test example 4()
Carry out, in the cladding material of test example 3, the evaluation of test example 3 being judged to be to the cladding material of A, carried out test example 4.
Acrylic-based adhesives is used to be attached by target coverage material to being bent on the base material of L font, as each test body by hot rolled steel plate (150mm × 75mm × 1.6mm).
With (3 hours) under the condition of (3 hours) under the condition of 50 DEG C →-30 DEG C for one-period carries out the repeatedly cold and hot of 10 cycles to test body, then by visually observing the state of cladding material thus evaluating.
Evaluation criterion is as follows respectively.Result is as shown in table 1-1 ~ 1-3.
A: without exception
B: top layer slightly cracks
C: marginal portion cracks
