5、方法,以便合理组织木材干操生产,科学评定木材干燥设备,改善干燥质量,提高经济效益,发展我国木材干燥事业,提高科学技术水平,特制定本标准。国外尚无此项标准,但有与本标准部分内容有关的其他标准与技术资料,如原苏联《木材窑干技术指南》介绍的关于周期式干燥室针阔叶树锯材低温及高温干燥基准,标准木料,干燥室生产t的计算,实际木料与标准木料的换算,以及在计算中需要确定的干燥时间的计算等,都作为本标准的定义及附录(附录A,附录B,附录C)加以引用,使本标准的项目检测与计算方法比较先进、完整而具体,操作性较强。本标准与LYJ118-1989《木材干燥工程设计规范》中的有关内容进行了协调(如干澡室年运行
6、时间等),对“标准木料”的条件作了修改(如树种、厚度等);并参照了《林产工业设计节能技术规定》。由于木材干燥方法与干燥设备较多,其技术性能与检测方法也较广。本标准仅就目前生产上使用较多,占有一定技术资料与经验,具有一定实践基础的项目进行立项,其他有待补充。本标准附录A,附录B,附录C都是标准的附录。本标准由原中华人民共和国林业部提出。本标准由中国木材标准化技术委员会归口。本标准由东北林业大学负责起草。本标准主要起草人:朱政贤、艾沐野、张晓峰、姜日顺、陈广元。中华人民共和国国家标准锯材干燥设备性能检测方法GB/T17661-1999Detectionmethodofdryingequip
7、mentsperformanceofsawntimber范围本标准规定了锯材于燥设备的技术性能及其检测方法。本标准适用于锯材常规干燥、除湿干燥、真空干燥及太阳能干燥的干燥生产、干燥工程设计及科学研究等。2引用标准下列标准所包含的条文,通过在本标准中引用而构成为本标准的条文。本标准出版时.所示版本均为有效。所有标准都会被修订,使用本标准的各方应探讨使用下列标准最新版本的可能性。GB/T153-1995针叶树锯材GB/T4817-1995阔叶树锯材
