Status: active
Page Count: 26
ICS Code (Heat. Calorimetry): 17.200.10
ICS Code (Surface treatment): 25.220.20
scope:

This Standard specifies the test method of cyclic heating under temperature gradi-ent1)for evaluating the thermal-barrier performance and the cyclic heat resistance of thermal-barrier coatings provided for high-temperature components such as burners, rotating blades and stationary blades of power-generation gas turbines, aircraft engines and so on.

Also, this Standard is applicable to the evaluation test for the thermal-barrier per- formance and the cyclic heat resistance of functionally gradient materials.

NOTE : The International Standard corresponding to this Standard and the sym-bol of degree of correspondence are as follows.

ISO 13123:2011 Metallic and other inorganic coatings-Test method of cyclic heating for thermal-barrier coatings under temperature gradient (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard andJIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.

Note 1) The temperature gradient in this Standard means the temperature field close to the actual environment in which a temperature gradient is inten- tionally provided by heating the surface of test piece and cooling the back- side thereof, which is different from the test method of cyclic heating under isothermal field specified inJIS H 8451.
