Standard Specification for Vitrified Clay Liner Plates
ABSTRACT
This specification establishes the criteria for the acceptance of vitrified clay liner plates used to protectively line or face pipe, culverts, abutments, structures, or appurtenances. Linear plates manufactured shall be known as curved linear plates or flat liner plates. These plates shall be manufactured from fire clay, shale, surface clay, or a combination of these materials that, when formed into liner plates and fired to suitable temperatures, yield a product that is strong, durable, serviceable, and free of objectionable defects. The absorption of liner plates shall not exceed 6%. The liner plates shall be subjected to acid resistance test. These liner plates shall be uniformly vitrified throughout their thickness and have a homogeneous structural texture.
SCOPE
1.1 This specification establishes the criteria for the acceptance of vitrified clay liner plates used to protectively line or face pipe, culverts, abutments, structures, or appurtenances.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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 C479-04(2022) is the internationally recognized standard specification for vitrified clay liner plates. Developed by ASTM International, this standard establishes the essential criteria for the acceptance and use of vitrified clay liner plates in infrastructure and construction projects. These plates serve as protective linings or facings for pipes, culverts, abutments, and various structural appurtenances, helping to extend the lifespan and improve the durability of these components. The specification covers both curved and flat liner plate designs, and mandates requirements for materials, performance, dimensional tolerances, and workmanship.
Key Topics
- Material Requirements: Liner plates must be manufactured from fire clay, shale, surface clay, or a suitable blend. The firing process must yield a strong, durable, and defect-free product.
- Types of Liner Plates: The standard covers curved liner plates and flat liner plates, addressing their usage according to structural demands.
- Absorption Rate: The water absorption of vitrified clay liner plates must not exceed 6%, ensuring durability and consistent performance.
- Acid Resistance: Plates are tested for resistance to acid exposure. The acid-soluble matter from the plates must not exceed 0.25% if such testing is specified.
- Uniform Vitrification: Plates must be homogeneously vitrified throughout their entire thickness to guarantee structural integrity.
- Dimensional Tolerances: The standard specifies strict dimensions and permissible variations for length, width, thickness, and the design of the tenon ribs.
- Workmanship: Plates must be free of significant defects such as cracks, chips beyond set limits, and blisters. A high-quality finish and consistent appearance are required for all products.
Applications
Vitrified clay liner plates covered by ASTM C479-04(2022) are widely used in a range of civil engineering and construction applications where chemical resistance, durability, and serviceability are imperative. Key applications include:
- Pipeline Protection: Lining for sewer pipes, culverts, and stormwater conduits to enhance chemical and abrasion resistance.
- Structural Lining: Protective facing for abutments and structural supports in bridges, tunnels, and retaining walls.
- Industrial Infrastructure: Used in areas where exposure to acids or other chemicals is probable, boosting longevity in harsh environments.
- Appurtenances: Lining or facing for tanks, chambers, and ancillary structural components to prevent corrosion and ensure a durable, low-maintenance solution.
By meeting ASTM’s stringent requirements, vitrified clay liner plates ensure consistent performance, supporting safe and sustainable infrastructure across public works, transportation, and industry sectors.
Related Standards
Organizations and professionals specifying or handling vitrified clay products can benefit from understanding related ASTM standards, including:
- ASTM C301 - Test Methods for Vitrified Clay Pipe: Provides methods for testing the material and performance characteristics of vitrified clay.
- ASTM C43 (Withdrawn 2009) - Terminology of Structural Clay Products: Offers definitions relevant to the types of clays and products used in these applications.
Many projects in the construction and civil infrastructure fields refer to these and other ASTM standards to ensure regulatory compliance, safety, and optimal product performance.
