ASTM F2135-01(2022)

Standard Specification for Molded Drain, Waste, and Vent (DWV) Short-Pattern Plastic Fittings

ABSTRACT
This specification covers standard fitting geometries for molded short-pattern plastic fittings intended for use in drain, waste, and vent applications. Fittings meeting the requirements of this specification are designed for use with outside-diameter controlled pipe. The body inside diameter can vary significantly as the wall thickness and outside diameter varies, and therefore, is not suitable for use as a fitting socket. Compliance to the specified centerline radius of curvature of short-pattern ¼ bends and the side branch of short-pattern sanitary tees shall be tested.
SCOPE
1.1 This specification covers standard fitting geometries for molded short-pattern plastic fittings intended for use in drain, waste, and vent applications.  
1.2 Fittings meeting the requirements of this specification are designed for use with outside-diameter controlled pipe. The body inside diameter can vary significantly as the wall thickness and outside diameter varies, and therefore, is not suitable for use as a fitting socket.  
1.3 Fittings meeting the requirements of this specification shall be tested in accordance with the applicable requirements of Specifications D2661 or D2665.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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 F2135-01(2022) is the globally recognized standard specification for molded drain, waste, and vent (DWV) short-pattern plastic fittings. Developed by ASTM International, this specification defines the requirements for plastic fittings intended for use in DWV systems. These fittings are designed for use with outside-diameter controlled pipe and are integral to proper piping installation and function in residential, commercial, and industrial plumbing systems.

Key Topics

• Short-Pattern Fitting Geometries: Specifies the dimensional requirements for common DWV fittings such as quarter bends, sanitary tees, wyes, and vent tees.
• Material Compatibility: Fittings are designed for outside-diameter controlled piping and are intended for use with thermoplastic pipes.
• Fitting Dimensional Tolerances:
  • Ensures geometric conformity for bends and tees, particularly concerning centerline radius of curvature.
  • Internal diameters may vary significantly; body inside diameter is unsuitable as a fitting socket.
• Testing and Compliance:
  • Fittings must be tested according to ASTM D2661 or ASTM D2665, which cover ABS and PVC DWV pipes and fittings.
  • Measurement of specific radii and alignment of branches is required to verify compliance with the standard.
• Threaded Fittings: Any short-pattern fittings with tapered threads must comply with ASTM F1498.
• Safety and Regulatory Considerations: Users are responsible for applying appropriate safety, health, and environmental practices, as well as ensuring compliance with regulatory limitations.

Applications

ASTM F2135-01(2022) is primarily used in the fabrication and installation of plastic piping systems for:

• Residential and Commercial Plumbing: Ensures compatibility and reliable function of DWV plastic fittings in bathrooms, kitchens, laundry facilities, and broader building infrastructure.
• Industrial Drainage Systems: Suitable for process waste and venting applications in non-pressurized piping circuits where reliable conveyance of waste fluids and gases is required.
• Drainage and Ventilation Upgrades: Assists plumbers, contractors, and manufacturers in selecting fittings that conform to standardized geometries, facilitating correct installation and system maintenance.
• Quality Control and Manufacturing: Provides manufacturers with a specification to standardize the production and inspection of DWV plastic fittings, ensuring consistent quality and performance.

Related Standards

For effective implementation, ASTM F2135-01(2022) references and aligns with several other important ASTM standards:

• ASTM D2661: Specification for Acrylonitrile-Butadiene-Styrene (ABS) Schedule 40 Plastic Drain, Waste, and Vent Pipe and Fittings.
• ASTM D2665: Specification for Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings.
• ASTM D2122: Test Method for Determining Dimensions of Thermoplastic Pipe and Fittings.
• ASTM D2749: Symbols for Dimensions of Plastic Pipe Fittings.
• ASTM F1498: Specification for Taper Pipe Threads 60° for Thermoplastic Pipe and Fittings.

Practical Value

By standardizing the geometries, testing methods, and material compatibility for short-pattern DWV plastic fittings, ASTM F2135-01(2022) enables:

• Interchangeability among fittings from different manufacturers.
• System reliability and safety in waste and vent piping.
• Streamlined installation for plumbing professionals.
• Regulatory compliance for code officials and inspectors.
• Consistent product quality for manufacturers and suppliers.

For stakeholders involved in plumbing system design, installation, and inspection, conforming to ASTM F2135 ensures compatibility, durability, and efficiency in drain, waste, and vent applications using plastic pipe fittings.
