What categorization applies to a standard with a life expectancy over 10 years?

When evaluating standards based on their life expectancy, categorizing a standard with a life expectancy over 10 years as a permanent standard is appropriate. This classification implies that the standard is designed to remain in effect for a significantly long duration, providing stability and consistency over time. Permanent standards are typically established with the expectation that they will not require frequent updates or changes, allowing users to rely on them for an extended period.

In contrast, other categories such as temporary or semi-permanent standards indicate shorter life spans and suggest that they may be subject to revision or replacement. Temporary standards, especially, are implemented for limited durations and are meant to address specific, often immediate, needs. The concept of an initial standard typically refers to the first version or draft of a standard, rather than its longevity. Therefore, the classification of a standard with a life expectancy over 10 years as a permanent standard reflects its intended stability and long-term use.
