ASTM F1470 – Standard Practice for Fastener Sampling for Specified Mechanical Properties and Performance Inspection

Scope

ASTM F1470 is a standard practice that outlines methods for determining the appropriate sample size of fasteners for mechanical property and performance testing. This standard ensures a statistically valid evaluation of a fastener lot, helping determine if the fasteners meet the specified quality requirements.

The standard acknowledges two primary quality control systems: detection and prevention. Detection relies on inspection to identify defects after production. Prevention emphasizes proactive measures throughout the manufacturing process to minimize defects. ASTM F1470 focuses on sampling plans for both approaches.

The standard clarifies that it addresses sampling for mechanical properties, physical properties, performance characteristics, coating requirements, and other quality criteria defined by ASTM Committee F16 standards. For dimensional and thread criteria, separate sampling plans under ASME Committees B18 are recommended.

A crucial aspect of ASTM F1470 is ensuring random sampling. This means each fastener in the lot has an equal chance of being selected for testing. The standard discourages practices like selecting fasteners only from the container top or from a single container in a multi-container lot.

When applying ASTM F1470, the purchaser (typically the engineer or builder) should consider the supplier’s quality assurance system. This can be achieved through audits or by verifying third-party certifications like ISO/TS 16949 or ISO 9001, which indicate robust quality management.
