What durability tests assess
BHMA explains that durability ratings consider function after repeated use and describes cycle tests simulating use through repeated opening and closing. They do not assess appearance alone.

Fields to record when reading a report
Record the test item, model configuration, test basis, cycle conditions and acceptance result. Equal counts with different actions or loads should not be ranked solely by numerical size.
- Was the complete lock tested or a component?
- Which actions does a cycle include?
- What post-test conditions determine a pass?
Why cycles cannot be converted to life
Actual environments, installation conditions and operation differ. Dividing cycle count by daily uses gives only an arithmetic estimate, not a product-life or warranty promise.
