IPC-A-610D里的Class 2指的应该是产品级别分类，具体为专用服务类电子产品，
稽核无非是文件与现场，合同，程序，办法，规范，标准等等，以你的说法，
感觉重点会在厂内产品检验规范是否符合IPC Class 2, 引一下摘录供参考，建议
楼主还是抓紧温习一下。
1.4.1 Classification
The customer (user) has the ultimate responsibility for
identifying the class to which the assembly is evaluated.
Documentation that specifies the applicable class for the
assembly under inspection needs to be provided to the
inspector.
Accept and/or reject decisions needs to be based on applicable
documentation such as contracts, drawings, specifications,
standards and reference documents. Criteria defined in
this document reflect three classes, which are as follows:
Class 1 — General Electronic Products
Includes products suitable for applications where the major
requirement is function of the completed assembly.
Class 2 — Dedicated Service Electronic Products
Includes products where continued performance and
extended life is required, and for which uninterrupted service
is desired but not critical. Typically the end-use environment
would not cause failures.
Class 3 — High Performance Electronic Products
Includes products where continued high performance or
performance-on-demand is critical, equipment downtime cannot
be tolerated, end-use environment may be uncommonly
harsh, and the equipment must function when required, such
as life support or other critical systems.
