Показать описание
Fold endurance measures the durability of paper when repeatedly folded under constant load; determining how many times the paper can be folded until it breaks. The folding strength is quoted as the number of double folds and the folding endurance is the log10 of the number of double folds.

The test is primarily used for testing papers that are frequently handled such as currency (bank note) papers, maps and wrapping papers. The ageing characteristics of a paper can be assessed by measuring fold endurance before and after accelerated environmental ageing.
