ASTM F1890-23 PDF

Overview

ASTM F1890-23 is the internationally recognized standard test method for measuring the performance factor of softball and baseball bats. Developed by ASTM International, this standard provides a precise laboratory method for quantitatively comparing bat performance using the bat-ball coefficient of restitution (BBCOR) and Bat Performance Factor (BPF). Applicable to bats of any construction or material, ASTM F1890-23 ensures consistent and reliable results that are critical for manufacturers, regulatory bodies, and sports organizations involved in quality assurance and compliance for baseball and softball equipment.

Key Topics

• Bat-Ball Coefficient of Restitution (BBCOR): Measures the ratio of the relative speed after impact to the relative speed before impact between a bat and a ball.
• Bat Performance Factor (BPF): Derived as the ratio of BBCOR to the ball's coefficient of restitution (COR), offering a single, comparative figure for bat performance.
• Test Applicability: Suitable for all types of softball and baseball bats, regardless of material or construction method.
• Laboratory Test Equipment: Outlines requirements for test balls (tested for weight, compression, size, and COR) and precise apparatus for measuring inbound and rebound speeds of both bat and ball.
• Test Conditions: Specifies environmental controls for temperature and humidity to ensure repeatable and accurate results.
• Reporting Requirements: Details the essential data points to be recorded, such as test operator identity, calibration data, equipment used, and detailed performance results.

Applications

The ASTM F1890-23 standard test method is widely used across the following areas:

• Bat Manufacturing and Product Development: Bat manufacturers utilize this method to test and demonstrate compliance of their products with industry regulations and performance expectations.
• Certification and Quality Assurance: Organizations, leagues, and regulatory bodies use the standard to verify that bats conform to designated performance limits, such as BBCOR regulations set for competitive play.
• Research and Development: R&D teams in sporting goods companies apply the method to compare current products, innovate new designs, and analyze bat dynamic performance quantitatively.
• Comparative Analysis: Enables objective benchmarking of different bat models, aiding selection for both consumers and professional teams.
• Safety and Fairness in Sport: By standardizing bat performance testing, the method helps to maintain a level playing field and ensures equipment safety for players.

Related Standards

ASTM F1890-23 references and complements several important standards for baseball and softball equipment testing:

• ASTM F1887 - Test Method for Measuring the Coefficient of Restitution (COR) of Baseballs and Softballs: Used for determining the energy restitution properties of balls.
• ASTM F1888 - Test Method for Compression-Displacement of Baseballs and Softballs: Assesses the compression characteristics of balls for consistency and safety.
• ASTM F2398 - Test Method for Measuring Moment of Inertia and Center of Percussion of a Baseball or Softball Bat: Measures key physical properties of bats relevant to their performance.

By adhering to ASTM F1890-23 and its related standards, stakeholders in the baseball and softball industries can ensure consistency, comparability, and regulatory compliance in bat performance testing. This contributes to product quality, player safety, and fair competition in the sport.
