This Specification covers a statistical sampling plan for lot inspection by attributes. It verifies that the customer's specified quality level (SQL) is not being exceeded. The estimate of fraction nonconforming determined by EIA Interim Standard No. EIA-554 is used to select the optimum sample plan for verifying that a given lot meets the specified quality level (SQL).

This standard is intended to provide a uniform method of determining proportion nonconforming in finished components and to provide a standardized definition of the quality index referred to as PPM. The method used here is primarily directed at components whose production or procured volume is large enough, during some predefined sampling period, to give statistically meaningful information.

This Assessment Guide is applicable to any assessment technique that wishes to embrace the principles and concepts presented in the EIA-599 National Electronic Process Certification Standard.

This standard specifies services whose architecture can be described in the context of the physical layer architecture (1) and the data link layer architecture (2) of the ISO Open Systems Interconnection Basic Reference Model - ISO 7498.

This Standard defines a machine coordinate system and machine motion nomenclature for numerically controlled machines. This Standard applies to all numerically controlled machines. For the sake of simplicity, the majority of the text of this Standard is written in terms which are applicable to machine tools but it is nevertheless applicable to numerically controlled machines in general.

This standard is intended to provide a uniform method of calculating an estimate of the proportion nonconforming in finished components and to provide a standardized definition of the quality index referred to as Average Outgoing Quality (AOQ). The method used here is primarily directed at components whose production or procured volume is large enough, during some predefined sampling period, to give statistically meaningful information.

This document is applicable to electronic component and equipment manufacturing.

Conventional attribute sampling plans based upon nonzero acceptance numbers are no longer desirable. In addition, emphasis is now placed on the quality level that is received by the customer. This relates directly to the Lot Tolerance Percent Defective (LTPD) value or the Limiting Quality Protection of MIL-STD-105. Measuring quality levels in percent nonconforming, although not incorrect, has been replaced with quality levels measured in parts per million (PPM). As a result, this standard addresses the need for sampling plans that can augment MIL-STD-105, are based upon a zero acceptance number, and address quality (nonconformance) levels in the parts per million range. This document does not address minor nonconformances, which are defined as nonconformances that are not likely to reduce materially the usability of the unit of product for its intended purpose.

The procedure outlined in this document is applicable to any manufacturing or service process. It may be used on part of a process or and entire process or a series of sequential processes.

This standard specifies requirements for the approval and maintenance of a manufacturer's capability and the procedures for the test and release of passive electronic components manufactured under capability approval. It also includes requirements for generic specifications that invoke this standard. It applies to all passive electronic components to be released under the capability requirements of an EIA generic and/or sectional and/or detail specification.

This standard is intended to provide guidance for selecting standardized methods for estimating the proportion nonconforming expressed as PPM. These methods are contained in EIA 554-1, EIA 554-2 and EIA 591.
