ASTM D6713-21 PDF

Overview

ASTM D6713-21 is the internationally recognized standard specification for extruded and compression molded shapes made from Poly(Vinylidene Fluoride) (PVDF). Developed by ASTM International, this standard sets forth the requirements for the material, dimensional tolerances, workmanship, and physical property performance of extruded sheet, rod, and tubular bar manufactured from PVDF. Products are categorized by type, class, and grade based on resin and filler composition, ensuring suitability for a variety of industrial applications.

Key Topics

• Product Scope and Classification

  • Covers requirements for extruded and compression molded PVDF shapes including sheets, rods, and tubular bars
  • Classification system distinguishes products by type, grade (e.g., unmodified, general purpose, recycled), and class

• Material and Dimensional Properties

  • Establishes criteria for tensile strength, elongation, tensile modulus, dimensional stability, flexural modulus, and Izod impact resistance
  • Defines dimensional properties: diameter tolerance, roundness, camber, thickness tolerance, length camber, and width bow

• Testing and Quality Assurance

  • Specifies standardized testing methods and minimum property values
  • Sampling guidelines ensure adequate inspection of each production lot
  • Certification requirements for product compliance and recycled content, if applicable

• Workmanship and Appearance

  • Products must be free from surface defects, voids, and foreign materials larger than specified tolerances
  • Uniform color and quality finish are required unless otherwise agreed upon in the purchase order

Applications

PVDF shapes produced according to ASTM D6713-21 are widely used in industries where excellent chemical resistance, mechanical strength, and dimensional stability are critical. Typical applications include:

• Chemical Processing Equipment

  • Components such as piping, tanks, and fittings benefit from PVDF's resistance to acids, bases, and solvents

• Semiconductor Manufacturing

  • Use in ultra-pure water systems and corrosion-resistant parts

• Water Treatment and Environmental Systems

  • Reliable performance in harsh and corrosive environments

• Food and Pharmaceutical Industries

  • Applications requiring high purity and ease of cleaning due to PVDF's low extractables

• Electrical and Electronics

  • Insulating components and supports due to PVDF's dielectric properties

The standard enables manufacturers and end-users to specify PVDF products that uniquely fit their needs, including the use of recycled materials when sustainability is a priority.
