IEC 61439-6 also recognizes that BTS are used in diverse, often challenging, environments. The standard acknowledges that these systems can be installed in ships, on rail vehicles, or in publicly accessible areas operated by unskilled persons. When this is the case, supplementary requirements from other standards (e.g., IEC 60092 for ships or IEC 61373 for railway applications) must also be satisfied.
