The term "normal damage" is not a commonly used phrase in everyday language. However, it could refer to any type of damage that is considered typical or expected for a particular situation or object. For example, if you were discussing insurance claims for car accidents, the phrase might be used to describe minor damages such as scratches or dents that are not severe enough to constitute "major" or "catastrophic" damage. In this context, it would imply that while there may be some level of damage, it is considered within acceptable limits and does not require extensive repairs or compensation.
