ASTM F1470-24

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

SIGNIFICANCE AND USE
4.1 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 multi-container lots.  
4.2 The purchaser should be aware of the supplier's quality assurance system. This can be accomplished by auditing the supplier's quality system, if qualified auditors are available, or by third-party assessment certification, such as provided by IATF 16949, or ISO 9001.
SCOPE
1.1 This practice 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 practice is for mechanical properties, physical properties, performance 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 practice provides for two sampling plans: one designated the “detection process,” as described in Terminology F1789, and one designated the “prevention process,” as described in Terminology F1789.  
1.4 This practice is intended to be used as either a Final Inspection Plan for manufacturers, or as a Receiving Inspection Plan for purchasers/users. It is not valid for third-party qualification testing.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1470-24: Standard Practice for Fastener Sampling for Specified Mechanical Properties and Performance Inspection is an international standard developed by ASTM Committee F16. This practice outlines procedures for sampling fasteners in order to determine the acceptability or disposition of a lot based on their mechanical, physical, performance properties, and coating requirements. It supports manufacturers, purchasers, and users in achieving consistent fastener quality through both detection and prevention sampling processes.

ASTM F1470-24 is intended for use in final inspection plans by manufacturers and receiving inspection plans by purchasers or users. It is not valid for third-party qualification testing. The standard emphasizes random selection of samples to avoid bias, ensuring that all items in a lot have an equal chance of selection.

Key Topics

• Random Sampling Requirements

  • All fastener samples must be selected randomly from the entire lot to ensure unbiased inspection.
  • Avoid localized sampling from only the top or from a single container of a multi-container lot.

• Sampling Plans

  • Detection Process: Uses inspection as the primary quality control method, including in-process and final inspections.
  • Prevention Process: Focuses on advanced quality planning, integrating methods such as statistical process control to prevent defects and achieve continuous improvement.

• Quality Assurance Systems

  • Purchasers are encouraged to verify supplier quality systems. Acceptable verification methods include audits by qualified personnel or third-party certifications like ISO 9001 or IATF 16949.

• Sample Size Determination

  • The standard provides specific guidelines for determining sample sizes based on lot size and fastener characteristics.

• Acceptance Criteria

  • Lots are accepted if zero nonconforming parts are found in the sample; a single defect results in rejection.

• Disposition of Nonconforming Lots

  • Options include scrapping, sorting and reworking, concession procedures, or downgrading for alternate applications, always with traceable documentation.

• Control of Measuring and Test Equipment

  • All measurement and test equipment must be properly controlled and maintained per established quality management standards.

Applications

Manufacturing

• Final Inspection Plans: Manufacturers apply ASTM F1470-24 to confirm each lot meets the required mechanical and performance properties before shipment.
• Quality Control: Supports implementation of robust detection and prevention quality processes, leading to improved overall product reliability.

Procurement and Receiving

• Receiving Inspection Plans: Purchasers use this standard to inspect incoming fastener lots, ensuring compliance and reducing the risk of nonconforming products entering use.
• Supplier Assessment: Enables purchasers to audit or request third-party certification of supplier quality systems.

Industry Sectors

• Automotive, Aerospace, Construction: Ensures critical fastener performance and safety through consistent sampling and inspection practices.
• Distribution: Distributors use the standard to manage the quality and disposition of fasteners within their inventory and supply chain.

INTRODUCTION
Throughout this practice 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 practice.
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, to achieve process stability and improve the capability
by reducing the variability.
ISO 9001 and IATF 16949 quality system standards, or a combination thereof, are models that may
be used in establishing a prevention-based quality system.
