arranged forward in proper order; there is no specific reference content;

the deletion does not affect the understanding and use of the standard;

-- Modify the terms and definitions of "batch" to conform to industry habits

and for convenience of use (see 2.1);

when the batch size is 1, which is convenient for operation (see Table 1);

custom (see Chapter 4).

For convenience of use, this Standard makes the following editorial changes:
