Standard Guide for Fastener Sampling for Specified Mechanical Properties and Performance Inspection

SIGNIFICANCE AND USE
Sampling shall be selected in a random manner, ensuring that any unit in the lot has an equal chance of being chosen. Sampling should not be localized by selections being taken from the top of a container or from only one container of multicontainer lots.
The purchaser should be aware of the supplier’quality assurance system. This can be accomplished by auditing the supplier’ quality system, if qualified auditors are available, or by third-party assessment certification, such as provided by QS 9000, ASQ 9000, or ISO 9000.
SCOPE
1.1 This guide provides sampling methods for determining how many fasteners to include in a random sample in order to determine the acceptability or disposition of a given lot of fasteners.
1.2 This guide is for mechanical properties, physical properties, coating requirements, and other quality requirements specified in the standards of ASTM Committee F16. Dimensional and thread criteria sampling plans are the responsibility of ASME Committee B18.
1.3 This guide provides for two sampling plans: one designated the "detection process," as described in Terminology F 1789, and one designated the "prevention process," as described in Terminology F 1789.

This standard is issued under the fixed designation F 1470; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Throughout this guide the terms detection and prevention apply to quality control systems. A brief
description of both is provided to assist the purchaser in the application of this guide.
The detection system relies on inspection as the primary means of controlling the quality of
furnished material. Methods include in-process and final inspection. In-process inspection is typically
performed by the individual performing the process and generally includes a first-piece inspection by
someone other than the operator. Quality-control inspection may perform audit inspections on the
process output during the course of the production run. In addition, a final inspection is performed by
quality control inspectors according to a prescribed sample plan. The other sample plans utilize zero
defects as their acceptance criteria.
The prevention system uses advanced quality planning in addition to many of the techniques used
in the detection system. Quality planning incorporates a systems approach to quality control that
focuses on defect prevention and continual improvement. In addition, Statistical Process Control
(SPC) is usually applied to control the process, thereby reducing the variability of the output.
The ISO 9000, QS 9000, and the ASQ Q9000, quality system standards, or a combination thereof,
are models that may be used in establishing a prevention-based quality system.
