The technical differences between this standard and ISO 28764.2015 and their reasons are as follows.

---5.1.1 The shape and size requirements of the special sample are increased. "Other test methods are specified for the sample. Other sizes or

The shape of the model" to meet the shape and size requirements of the specific specifications specified in the specific inspection items in China's enamel field standards.

This standard has made the following editorial changes.
