ASME A112.19.2 Ceramic Plumbing Fixtures

Developed by the American National Standards Institute (ANSI), the ASME A112 standards constitute a comprehensive series of more than forty plumbing standards that provide performance expectations and testing for a wide variety of plumbing products and assemblies. Some of these products include:

• bathtubs
• Bidets
• Drinking fountains
• sinks
• Shower bases
• sinks
• Urinals
• Water closets
• Flexible water connections
• Plastic, stainless steel and cast iron waste fittings

Although standards are specific to a particular product type or assembly, many of these standards have overlapping performance and durability testing requirements. For example,

• ASME A112.19.1 / CSA B45.2 Enameled cast iron and enameled steel plumbing fixtures)
• ASME A112.19.2 / CSA B45.1 Ceramic sanitary fittings
• ASME A112.19.3 / CSA B45.4 Stainless steel plumbing fixtures

standards have several overlapping test methods, such as field-installed tile flange sealing testing, overflow testing for sinks and basins, and bend testing. These standards provide requirements for product design, material durability, and overall structural performance.

It is natural for consumers to assume that the tubs and toilets they purchase and use will withstand normal use. It is reasonable to expect tubs not to crack and fixtures to last over time. ASME A112 standards define normal use through performance, material requirements, and durability testing. Products tested under ASME A112 standards must undergo rigorous testing procedures to ensure that products and assemblies will perform over the normal life of a product.

When implemented, ASME A112 standards help ensure that plumbing products and assemblies perform as intended in residential and commercial environments. Plumbing manufacturers have the responsibility to prove to local authorities and other authorities having jurisdiction that all plumbing products, components, and assemblies meet the requirements of the accepted plumbing code. Plumbing manufacturers can provide this evidence with a reliable, accredited third-party certification that their products, components, and assemblies meet the requirements of the appropriate ASME A112 standard, supported by test reports from an accredited, third-party testing laboratory.

This Standard covers vitreous and non-vitreous Chinese sanitary fittings and includes requirements for materials, construction, performance, testing and marking. The performance requirements and test procedures of this Standard apply to all types of toilets and urinals discharging into gravity drainage systems in permanent buildings and structures, regardless of occupancy.

This standard covers the following sanitary fittings: shower trays, bidets, drinking fountains, fittings for institutional applications, sinks, shower bases, bathtubs, urinals, toilets and restrooms, including: clinic sinks, kitchen sinks, laboratory sinks, laundry sinks, service sinks and utility sinks.

In short, the ASME A112.19.2 standard is designed for companies that manufacture plumbing materials and equipment to increase water conservation and comply with jurisdictional regulations, as well as government and other regulatory agencies.

The ASME A112.19.2 standard is important in the following respects:

• Ensures safety and hygiene. This standard ensures that fixtures are designed and manufactured to promote proper sanitation and hygiene. It helps prevent contamination of drinking water systems through appropriate backflow prevention design.
• Promotes uniformity and compatibility. This standard ensures consistency among products by defining dimensions and performance criteria. This uniformity facilitates installation and ensures compatibility with other installation components.
• Promotes water efficiency. Water consumption includes requirements to ensure fixtures are efficient and support water conservation efforts.
• Regulatory compliance. Frequently referenced in national plumbing codes. Compliance with ASME A112.19.2 may be a regulatory requirement for commercial and residential buildings in many jurisdictions.
• Product quality and performance. This standard includes tests for structural integrity, washdown performance and durability. It provides confidence to users, installers and inspectors by ensuring that products meet a baseline for quality and performance.
• Industry trust and recognition. ASME is a respected standards organization. Products that comply with ASME A112.19.2 standard signal reliability and quality to the marketplace.

For manufacturers, knowing whether products comply with ASME A112.19.2 can be critical for approval, inspection, and long-term performance. Some of the key test methods defined in this standard include:

• Water consumption test: Its purpose is to ensure that the fitting uses water efficiently. Using a calibrated container or flow meter, the volume of water used per flush is measured and recorded.
• Drain line carryover test: Purpose is to evaluate the ability of a toilet to carry waste through the plumbing system. Simulated waste (for example, soybean paste or toilet paper with plastic balls) is discharged through a test drain pipe approximately 30 meters. The average carryover distance is measured.
• Trap seal depth test: Its purpose is to verify the water seal in the trap (prevents sewer gases from entering). The vertical distance of the water in the trap after the flush is measured.
• Ball passability test: To check the ability of the fixture to pass solid waste. Standard synthetic test balls (5,1 inches (XNUMX cm) in diameter) are used to verify that they pass through the trap and outlet without blockage.
• Flush performance test: Its purpose is to verify that the toilet effectively flushes the bowl. Simulated waste (toilet paper and synthetic test media) is flushed multiple times. The toilet must be flushed continuously.
• Structural integrity/load testing: The purpose is to ensure that the fixture can support the expected user weight. Vertical static load is applied for a specified period of time without cracking or permanent damage.
• Glaze and surface quality: Its purpose is to ensure that the surface is smooth and easy to clean. It is visually inspected for defects (bubbles, cracks, roughness) and the surface resistance to cleaning products and abrasion is tested.
• Water tightness and leakage test: Its purpose is to confirm that tanks and traps are not leaking. The fixture is filled with water and monitored for leaks for a certain period of time.
• Backflow prevention / siphonage test: Its purpose is to ensure that contaminated water does not flow back into the drinking water. Vacuum conditions are created and it is checked whether there is siphonage or backflow from the fitting.

All of these tests are designed to ensure that fixtures are safe, durable and functional under real-world conditions.
