Quality Classifications (current extract from IPC-A-610)
Accept and/or reject decisions shall 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/Harsh Environment 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.
The customer (user) has the ultimate responsibility for identifying the class to which the assembly is evaluated. If the user and manufacturer do not establish and document the acceptance class, the manufacturer may do so. When IPC-A-610 is cited or required by contract as a stand-alone document for inspection and/or acceptance, the requirements of IPC J-STD-001 “Requirements for Soldered Electrical and Electronic Assemblies” do not apply unless separately and specifically required. In the event of conflict, the following order of precedence applies:
- Procurement as agreed and documented between customer and supplier.
- Master drawing or master assembly drawing reflecting the customer’s detailed requirements.
- When invoked by the customer or per contractual agreement, IPC-A-610.
When documents other than IPC-A-610 are cited, the order of precedence shall be defined in the procurement documents.
