ASTM C927 Standard Test Method for Ceramic Glass Decorated Lead and Cadmium Extracted from Glass Tumblers

ASTM C927 covers the measurement of lead and cadmium extracted by acetic acid from the lip and rim area of drinking glasses with ceramic glass enamels applied to the exterior for decoration. The extraction process may hasten the lead and cadmium release from the decorated area, acting as a harsh test that is unlikely to be replicated in the real-world circumstances in which such glassware is used. ASTM C927 is a lead and cadmium-specific test technique.

Introduction to ASTM C927

When ingested in excess, the heavy metals lead and cadmium are known to harm human health. Therefore, it’s crucial to gauge how much can be taken out of a section of the glass drinking vessel that comes into contact with the lip. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM C927 tests for our clients. The relative magnitude of metals extracted from one test specimen relative to another test specimen provides an effective tool for discrimination, even though the amount of lead and cadmium extracted by this test method is in no way representative of the amount of metals extracted by actual lip contact.

ASTM C927 Test Method

Lead and Cadmium extractionThe product under test’s lip and rim are leached for 24 hours at 20 to 24°C (68 to 75°F) using a 4% acetic acid solution to remove lead and cadmium. 
Atomic Absorption SpectrophotometryFor lead and cadmium, specific hollow cathode or electrodeless discharge lamps are used in atomic absorption spectrophotometry measurements. The results are expressed by using micrograms per milliliter (ppm) extracted from the glass’s internal volume. 

ASTM C927 Test Specimens

Specimen DetailAn ASTM C927 test specimen is a piece of chemically resistant borosilicate glassware. 
Specimen SizeSix identical units are taken and marked 7 mm below the rim. Each article’s internal volume is measured in milliliters by filling a graduated cylinder up to about 6 to 7 mm (1/4 in.) above the fill line.

ASTM C927 Test Result

The amount of lead and cadmium that has been eliminated from the lip and rim region of glass tumblers with ceramic glass enamels on the exterior is measured using the ASTM C927 test. This test method is unique to lead and cadmium.

ASTM C927 Related Tests

ASTM C927 is related to tests including ASTM C738 for cadmium and lead extraction from ceramic surfaces.
