Standard Practice for Sampling Forest Trees for Determination of Clear Wood Properties
N D5536
Annotation
This practice offers two alternative physical sampling procedures: cruciform sampling and random sampling. The choice of procedure will depend upon the intended use for the test results, the resources available for sampling and testing, and the availability of existing data on the mechanical properties and specific gravity of the species of interest.
A third procedure, double sampling, is included primarily by reference. This procedure applies the results of cruciform or random samples through correlation to improve or update property values.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Общепринятая практика для отбора лесных деревьев для определения ясных деревянных свойств
Эта практика предлагает две альтернативных физических процедуры выборки: крестообразная выборка и случайная выборка. Выбор процедуры будет зависеть от надлежащего использования для результатов испытаний, ресурсы, доступные для отбора и тестирования и доступности существующих данных по механическим свойствам и удельной массе разновидностей интереса.
