R48

R48 is an alphanumeric designation used in several different domains, and its meaning depends on the context. There is no single, universal definition for the term, so it functions as a label in various systems rather than as a standalone concept.

In transportation, R prefixes are commonly used to denote regional or secondary roads in certain countries. R48 can refer to a specific regional highway within such a road network. The exact route and its features vary by country, and the designation is tied to local routing schemes rather than to a global standard.

In chemical hazard labeling, R-phrases were used in older classification systems to describe health and environmental risks. R48, in that context, indicated that prolonged exposure to a substance could be harmful to health. Modern labeling practices have largely replaced R-phrases with more standardized hazard statements, though historical references to R48 may still appear in older documentation or literature.

R48 is also used as a model or part number in various products, including electronics, machinery, and consumer goods. As a product identifier, it conveys no inherent meaning about the item beyond its designation within a particular catalog or manufacturer’s system.

Because R48 spans multiple domains, it is important to determine the relevant field and source when interpreting the term. Without context, the designation remains ambiguous and could refer to a road, a hazard phrase from older labeling schemes, or an item code in a product lineup.
