Start of application The st
5、art of application of this standard is 1 June 2011. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 148 “Continuous handling equipment and systems Safety” (Secretariat: AFNOR, France). The responsible German body involved in
6、 its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-22-31 AA Stetigfrderer of Section Frdertechnik. Representatives of manufacturers and users of continuous handling equipment, and of the employers liability insurance associati
7、ons contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serve
8、s to facilitate proof of compliance with the essential requirements of the directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Mac
9、hinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO Sta
10、ndards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 741:2000-03 as follows: a) the standard has been revised and brought in line with the new Machinery Directive 2006/42/EC; b) Annex ZA (informative) “Relationship between this European
11、 Standard and the Essential Requirements of the EU Directive 2006/42/EC” has been modified in accordance with the new Machinery Directive 2006/42/EC.

DIN EN 741:2011-06 3EN 741:2000+A1:2010 (E) Introduction This European standard is a type C standard as defin
29、ed in !EN ISO 12100-1“. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for systems and components that have been designed and built accordin
30、g to the provisions of this type C standard. While producing this standard it was assumed that: - only trained persons operate the machine; - parts without specific requirements are: a) designed in accordance with the usual engineering practice and calculation codes, including all failures modes; b)
31、 of sound mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality; d) made of materials free of defects; - harmful materials, such as asbestos are not used as part of the system and components; - components and system are kept in good repair and wo
32、rking order, so that the required characteristics remain despite wear; - by design of the load bearing elements, a safe operation of the system and components is assured for loading ranging from zero to 100 % of the rated possibilities and during the tests; - the ambient air temperature is maintaine
33、d between - 15 C and + 40 C; - the relative humidity is kept between limits which do not impede the safe working of the system and components; - the components (see clause 3.4) are not exposed to external vibration; !deleted text“ - a negotiation takes place between the user / installer and the manu
34、facturer concerning the particular conditions for the use and places of use of the machinery; - the working area is adequately lit; - the places of installation allow a safe use of the system; - safety data sheets on the bulk materials to be conveyed are provided by the user / installer and are part
35、 of the design criteria. EN 617, EN 618 and EN 620 may need to be considered for a complete continuous handling system (machine). DIN EN 741:2011-06 4EN 741:2000+A1:2010 (E) 1 Scope 1.1 This standard specifies the special safety requirements for those types of fixed pneumatic handling systems and co
36、mponents as defined in clause 3, which are designed for conveying bulk materials on a continuous or an intermittent basis (batch conveying system) from the loading point(s) to the unloading point(s). 1.2 This European standard deals with the technical requirements to minimise the hazards listed in c
37、lause 4 which can arise during the operation and the maintenance of the pneumatic conveying system. when carried out in accordance with the specifications given by the manufacturer or his authorised representative. Annex A gives a list of hazards according to !EN ISO 12100-1“. and the safety require
38、ments and/or measures are specified in the same order as they are given in Annex A. 1.3 This standard applies to design, on site assembly, and commissioning stages. 1.4 This standard applies also to the built-in actuators and parts of the systems, which control the components. 1.5 Exclusions This st
39、andard does not specify the requirements for any elements used as a link between a fixed part(s) of the system and any other part mounted on mobile/movable supports (e.g.: ship, unloaders, .). This standard does not take into account the risks of burns and scalds by the radiation of heat sources or
40、by contact with hot gases. This standard does not take into account the risk generated by ionising materials used in measuring equipment (e.g. level indicators). This standard does not specify the requirements for handling specific hazardous materials, such as radiating material, explosives, explosi
41、ve gases, . This standard does not specify the requirements for hazards due to electrostatic charges of pipes and equipment made of non-metallic materials. The safety requirements for the transportation including loading and unloading of the components are not covered by this standard. This standard
42、 does not apply to pneumatic conveying systems used underground, for mining and in public areas. This European standard does not establish the additional requirements for: freezer applications, high temperatures, corrosive environments, strong magnetic fields, potentially explosive atmospheres, radi
43、oactive environment, operation on ships and earthquake effects, hazards during decommissioning. !This standard does not specify the requirements for hazards due to noise.“ 2 Normative references !The following referenced documents are indispensable for the application of this document.
