This part of ISO 12678 describes apparatus and specifies simple methods for routine measurement of corner and edge defects, as well as other surface imperfections of refractory bricks. It does not apply to the measurement of internal defects. It does not establish criteria for acceptance or rejection of bricks.
The application of these methods is limited to standard shapes in accordance with ISO 5019-1 to ISO 5019-6 and ISO 5417, unless otherwise agreed.
