What is the maximum error percentage allowed for timer intervals in tanning equipment?

The maximum error percentage allowed for timer intervals in tanning equipment is set at 10%. This standard is important because it ensures that consumers receive consistent and safe tanning sessions. If timers were allowed to have a larger error margin, there could be an increased risk of overexposure to ultraviolet (UV) radiation, which can lead to skin damage or increased chances of skin cancer. By maintaining a stricter limit, safety standards are upheld, ensuring that users don’t exceed the recommended tanning time. This limit helps to regulate the industry and protect public health by promoting safe tanning practices.
