除草机又被称为草坪机,由主轴、汽车发动机、行走轮、升降机构、刀头、护栏与控制组合而成。由平行面四杆移动机构,声卡机架、上下单翼除草设备,整个设备调偏设备,驱动链转动圆锥齿轮增长速度传动装置和驱动链仿型调深设备构成;速度比人力除草提升8至10倍,伤苗率不高,除苗清理率大。
FCC认证是啥?FCC认证分为三种,Certification,Doc,Verification,可以理解为FCC针对不同商品管控水平也有不同的:
1、Certification: 具备无线通信发射系统的商品,需要做FCC Certifiction(红外感应发射系统没有在管控范畴),其做法就是FCC认可的实验室将检验报告提交FCC或TCB(Telecommunications Certification Body),由FCC或TCB审核同意后签发 ID号。
2、Doc: 比较常见的主要产品有IT商品、微波炉加热、节能灯管、电子镇流器等。DOC是合规性宣布的简称(Declaration of Conformity) ,但和CE针对出示合规性报告的内容试验室没有限制不同的是,FCC的DOC汇报应由赢得了NVLAP CODE(美国医学实 验室认证管理系统)或A2LA(国外实验室认可研究会)核可的试验室才可以出示,NVLAP CODE或A2LA必须要在DOC汇报中列明,不然汇报视为无效。一定要注意:做DOC的商品还可以申请ID,即还可以做Certification。
3、Verification:比较常见的主要产品有音视频产品。由DOC一般认可的实验室出示检验报告就可以,需要注意的是,做 Verification的商品不可以申请办理ID,便是送FCC或TCB不会被审理。此外,FCC认证对产品的区划,是依据它的功能决定的,注:FCC的DOC汇报应由赢得了NVLAP CODE或A2LA的试验室才可以出示,NALAP CODE必须要在DOC汇报中列明,不然汇报视为无效。应当是: FCC的DOC汇报应由赢得了NVLAP CODE或A2LA CODE的试验室才可以出示,NVLAP CODE或A2LA CODE必须要在DOC汇报中列明,不然汇报视为无效。
