Provides producers and users of building poles with requirements for the visual grading of such timbers intended for use in structures.

This Standard sets out the minimum requirements for visually graded timber building poles with or without full-length preservative treatment, intended primarily for use in the framework (internal or external) of a building. These minimum requirements apply at the time of grading.This Standard does not cover requirements for strength and dimensions.NOTE: Requirements for strength and dimensions should be specified separately.
