About This Item
ASTM C738 is the ASTM standard titled Standard Test Method for Lead and Cadmium Extracted from Glazed Ceramic Surfaces. It provides a technical basis for evaluating how much lead and cadmium may be released from glazed ceramic surfaces under defined test conditions. That makes it useful for manufacturers, laboratories, and quality teams that need a consistent way to assess product performance, support compliance efforts, and compare glazed ceramic items with greater confidence.
Overview of ASTM C738
This standard focuses on a test method for extracting lead and cadmium from glazed ceramic surfaces, helping users measure potential release in a controlled and repeatable way. ASTM C738 is commonly used as part of product evaluation and quality control when glazed ceramic materials must be checked against applicable requirements or internal acceptance criteria. As a technical document, it supports more consistent testing practices and clearer comparison of results across different glazed ceramic products.
Common use cases of ASTM C738
ASTM C738 is commonly referenced when testing glazed ceramic items that may come into contact with food or other contents where extracted metals are a concern. It is useful in laboratory testing workflows, incoming product review, and ongoing production checks for glazed ceramic surfaces. The standard may also support supplier qualification and documentation when a buyer or manufacturer needs a recognized method for evaluating lead and cadmium extraction performance.
Benefits of using ASTM C738
Using ASTM C738 can help improve consistency in test results and reduce uncertainty when evaluating glazed ceramic surfaces. It gives procurement teams, manufacturers, and laboratories a shared method for assessing lead and cadmium extraction, which supports compliance-minded decision-making and product comparison. ASTM C738 also helps strengthen quality control by providing a repeatable approach that can be used in routine testing, verification, and risk reduction activities.
