True or False: Retroactive requirements are enforceable only for devices manufactured after a code's effective date.

The statement is true because retroactive requirements, as stipulated in many regulatory frameworks and codes, typically apply only to devices that are manufactured after the effective date of the code. This means that any new requirements or changes to existing regulations generally do not retroactively apply to devices that were manufactured before the implementation of those requirements.

The rationale behind this approach is to avoid imposing new standards on products that were already made and sold according to the rules in place at the time of their manufacture. Such measures aim to provide manufacturers and users of devices some clarity and stability, ensuring that they are not held accountable for compliance with standards that were not applicable when the devices were produced.

Moreover, this principle allows manufacturers to adapt to new regulations without facing undue burden from past decisions. This clarity also helps maintain fairness in the marketplace, allowing older products, which have complied with prior codes, to remain in use without needing retroactive upgrades or modifications.
