Legal Definitions - assay

Definition: Assay is a process of testing the purity of metals, especially gold and silver, through chemical experiments. It can also refer to an examination of weights and measures.

Examples:

• A goldsmith performs an assay on a piece of gold to determine its purity.
• A government agency conducts an assay on a batch of weights and measures to ensure they are accurate.

The first example illustrates how assay is used to test the purity of metals. A goldsmith may use various chemical tests to determine the amount of gold in a piece of jewelry or other object. This is important for determining its value and ensuring that it meets certain standards.

The second example shows how assay can also refer to an examination of weights and measures. This is important for ensuring that products are sold in accurate quantities and that consumers are not being cheated. Government agencies may conduct regular assays on various types of measuring devices to ensure they are accurate.
