ASTM C1466: Ceramic Foodware Lead Cadmium Gfaas Testing Services
ASTM C1466 is used to determine the amount of lead and cadmium extracted by acetic acid at room temperature from the food-contact surface of foodware. This test method uses graphite furnace atomic absorption spectroscopy (GFAAS).

What Is ASTM C1466 Ceramic Foodware Lead Cadmium Gfaas?
ASTM C1466 describes a standard procedure for determining the lead (Pb) and cadmium (Cd) extracted from the surfaces of ceramic and glass that contact food. These toxic heavy metals can migrate into any food or beverage when ceramic bodies or glazes are incorrectly formulated or fired.
The test procedure uses GFAAS, one of the most sensitive analytical techniques for detecting trace levels of Pb and Cd, as required by global food safety regulations. ASTM C1466, therefore, plays a vital role in consumer safety and the validation of ceramic foodware for consumer use.
Applications and Benefits of ASTM C1466 Ceramic Foodware Lead Cadmium Gfaas Testing
Scope
ASTM C1466 outlines procedures for determining the leaching of lead and cadmium from glazed ceramic and glass surfaces intended for food contact.
It evaluates:
- Release of Pb and Cd from food-contact surfaces
- Compliance with regulatory safety limits (FDA, CPSIA, and similar standards)
- Effect of acidic food simulants on metal migration
- Consistency and quality of ceramic glazes and coatings
The method simulates real food-use conditions through controlled acidic extraction.
Applications
- Testing plates, bowls, cups, mugs, and serving ware
- Evaluation of ceramic cookware and bakeware
- Quality control of decorative and glazed tableware
- Safety assessment of glass and crystal food-contact products
- Regulatory compliance and product certification
Benefits
- Ensures consumer safety by detecting toxic metal leaching
- Supports compliance with international food safety regulations
- Provides high-sensitivity measurement at ppb levels
- Identifies glaze formulation or firing issues
- Enhances product quality and brand reliability
Our ASTM C1466 Testing Procedure
Specimen Preparation
Ceramic foodware is inspected, cleaned, and prepared with intact glaze surfaces to ensure accurate extraction behavior.
1Leaching Solution Exposure
A 4% acetic acid solution is applied to food-contact areas to simulate acidic food conditions.
2Controlled Incubation
Samples are held at specified temperature and time conditions to allow potential migration of Pb and Cd into the solution.
3Analysis & Reporting
Extracted solutions are analyzed using GFAAS, and results are compared against regulatory safety limits.
