ISO 3129-2012 pdf free download.Wood – Sampling methods and general requirements for physical and mechanical testing of small clear wood specimens. ISO 3129 specifies methods for the extensive and limited sampling of wood, conditioning and preparation of test pieces. It also specifies the general requirements for physical and mechanical testing of small clear wood specimens. The sampling guidance provided in this International Standard can be applied for timber taken from either trees, logs, or pieces of ungraded/graded/presorted sawn timber for non-stwctural applications, such as furniture, windows, doors. etc., only. 2 Normative references The following referenced documents are indispensable for the application of this document.
