摘要：为了探讨GB/T 1941—2009《木材硬度试验方法》的修订依据,分析布氏(Brinell)硬度、金氏(Janka)硬度、硬度模量方法、表面硬度、Monnin硬度等试验方法的优缺点,并比较国内外木材硬度试验方法标准。其中金氏硬度方法以其方法简单、准确、高效,为ISO和各国广泛应用。针对GB/T 1941—2009的修订,建议增加生材硬度测试方法,同时为人造板(厚度>3 mm)和易裂木材补充硬度模量测试方法。
In order to provide evidences for revising the national standard of GB/T 1941—2009 Method of testing in hardness of wood,the authors analyzed the advantages and disadvantages of various wood hardness test methods such as the Brinell hardness method,the Janka hardness method,the hardness modulus method,surface hardness method,and the Monnin hardness method,etc.The standards on test methods of wood hardness in China and abroad were compared.Among these test methods,Janka hardness is the most widely adopted by ISO and many countries because it is very simple,accurate and efficient.GB/T 1941—2009 does not specify a hardness test method for green wood,therefore it is recommended to add in.The hardness modulus test method is proposed for the purpose of measuring the wood-based panel with a thickness greater than 3 mm and wood susceptible to crack.
