(1) classification of machinery
1. Functions: packaging machinery, printing machinery, textile machinery, plastic machinery, engineering machinery, machine tool processing machinery, etc
2. From the CE point of view, there is an important classification: dangerous machinery, non-hazardous machinery.
3. To explain the dangerous machinery and non-hazardous machinery.
4. The distinction between risk and non-risk is the difference in the way of authentication.
(2) the instructions involved in mechanical CE
1. Original mechanical instruction: Directive 98/37/EC effective date: August 12, 1998; Expiry date: 28 December 2009; Now machine instructions: Directive 2006/42 / EC effective time: on December 28, 2009. The machine under the instruction of standards: EN60204 - "on June 1, 97 in 2009 to terminate, at the same time be EN60204 1:20 06 version of the Safety of machinery - Electrical equipment of those - Part1: General requirements (IEC60204-1:05 (modified)) substitution, the new version valid time: on January 6, 2009
2. 2006/42/EC MD - mechanical instructions
3. 2006/95/EC LVD- low voltage instruction
4. 95/16/EC Lift (manned)
5. 90/396/EEC gas directive (with internal combustion engine)
6. 97/23 / EC Pressure Equipment Directive. PED
7. Pressure equipment: refers to containers, pipes, safety accessories, pressure accessories. 0.5*105 Pa pressure equipment
8. 94/9/EC anti-explosion instructions, etc
(3) standard of mechanical CE
? class A standards, basic standards, common standards
? annex 1, 98/37 / EC, EN iso12100-1-2 (mechanical security basic concept and design principles of the first part: the basic terminology and methods ), the second part: the technology principle, EN1050 (mechanical risk assessment) is LVD EN60204-1 mechanical electrical evaluation criteria At the same time with MD evaluation part.
? class B standard, product specific matters.
? EN811:1997 mechanical safety ─ prevent lower limbs stretch and hazardous area safety distance
? EN294 machinery safety ─ prevent the safe distance of upper limbs stretch and dangerous areas
? EN349 machinery safe ─ from each part of the human body squeezed minimum clearance
? EN418 stop device
? C standard, specific product standards (food machinery, packaging machinery, machine tool)
(4) the process of applying for mechanical CE
(5) test items for mechanical CE:
? the grounding continuity test: 10 a 50/60 hz see PE at the ends of the voltage drop
? leakage current test
? testing insulation resistance: 500 VDC > 1 megohm
? loop test
? withstand voltage test: 1000 v / 1 s insulation breakdown
? residual voltage test: below 60 v or within 5 s
? functional test: electrical equipment of electric function, particularly with safety related functions
? retest, devices and circuit has modified for a retest
