Final answer:
Electric toys must comply with safety standards that can vary by country, such as limits on hazardous materials like cadmium in batteries and regulations on voltage and amperage for safe operation.
Step-by-step explanation:
Electric toys must meet specific safety standards and regulations which can vary based on international trade rules and regional directives. For example, the European Union's Directive 2006/66/EC limits the cadmium content in batteries to improve environmental performance. However, it's important to note that the World Trade Organization (WTO) allows countries to set their own standards based on scientific evidence without unjustifiably discriminating between countries.
While these consumer safety standards may differ across nations, they commonly include regulations on electrical potential, amperage, and material composition to ensure safe operation and minimize environmental impact. Electric toys are often powered by batteries and must operate within specified voltage and amperage parameters to prevent malfunctions. Replacing or recharging batteries is typically necessary after a certain period, depending on the toy's usage.
