1 Основные отклонения а и b не предусмотрены для размеров менее 1 мм.
2 Для полей допусков от js7 до js 11 нечетные числовые значения IT могут быть округлены до ближайшего меньшего четного числа, чтобы предельные отклонения были выражены целым числом микрометров.
3 Специальный случай: поле допуска m 7 предусмотрено лишь для размеров свыше 3 мм.
