Standards for safety assurance of printing machinery I. domestic safety standards international standards organization voted to adopt ISO 12648 "printing technology - safety assurance system for printing machinery"

this is the first time that the international standards organization has specially formulated safety assurance standards for printing machinery. This standard integrates the American international standards organization b65.1 "safety standard system for printing machinery" and the draft standards for printing machinery formulated by Cen. It is the crystallization of several years' work by experts from Brazil, Japan, Germany, Sweden, the United Kingdom, the United States and other countries

this standard is applied to the printing machinery system. All mechanical driving equipment including auxiliary machinery are controlled by the same control system. It puts forward safety requirements for the design and manufacture of machinery, and discusses the well-known dangerous accidents in printing machinery, including mechanical protective devices, non mechanical dangerous accident protection, regulation and management devices, warning signal devices, etc

II. European safety standard

the safety of mechanical products is the primary prerequisite for its entry into the European market. Therefore, the EU has specially formulated unified European security standards

Cen divides mechanical safety standards into three types: A, B and C. In order to avoid repetition, formulate various standards in an orderly and rapid manner, and facilitate cross reference and mutual reference among various standards, the standard system wipes the steel plastic pipe zigzag testing machine as follows:

class a standard (basic standard), and gives the basic concept, design principles and general requirements for safety inspection of all machinery

class B standard (group safety standard) refers to a class of relevant safety devices that can be cross applied to a wide range of machinery in a safety field:

-- Class B1 Standard, a standard in a specific safety field (such as safety distance, surface temperature, noise)

-- class B2 Standard, relevant safety device (such as two hand control device, interlocking device, pressure sensitive device, protective device) standard

class C standard (machine safety standard) gives detailed safety requirements for a particular machine or unit

most of the class A and class B standards of European machinery safety standards are formulated by the technical committee of mechanical safety standards (cen/tc114), the technical committee of electrical standards (cenelec/tc44x), the technical committee of ergonomics standards (cen/tc122), etc. Class C product safety standards are formulated by technical committees of different professional standards

class C standards are generally formulated according to the principles specified in class a standards and the characteristics of their products. At the same time, class B standards are fully cited. In special cases, when formulating class C standards, the provisions of class B standards may not be followed, but other corresponding safety protection measures shall be specified in the standards

III. safety standard for printing machinery

when obtaining the CE mark, the manufacturer of printing machinery can directly control the design and production stages of products according to the European standard en1010 mechanical safety - machine safety in design and structure of printing machinery and paper processing machinery, so as to ensure that the products put into the European market meet the safety requirements. The standard consists of five parts:

e when installing the handsaw n. Safety of machinery - machine safety in design and construction of printing and paper processing machinery - Part 1: General requirements

en. Safety of machinery - machine safety in design and construction of printing and paper processing machinery - Part 2: printing and polishing machinery including proofing machines

en. Safety of machinery - machine safety in design and construction of printing and paper processing machinery - Part 3: paper cutting machinery

en safety of machinery - machine safety in design and construction of printing and paper processing machinery - Part 4: binding machinery - paper processing and finishing machinery

en. Safety of machinery - Safety of machinery in the design and construction of printing machinery and paper processing machinery - Part 5: energy saving products for buildings: machinery for the production and processing of corrugated board

this standard is formulated by the Technical Committee on printing and paper machinery standards (cen/tc198). The standard complies with the basic requirements of the machinery directive and the regulations of the European Free Trade Association. It is a class C standard that can be directly used to guide the design and production of machines

the safety measures for machinery hazard protection and covered hazardous areas in this standard comply with the safety requirements of ergonomics. The "definitions - technical terms - Symbols - Abbreviations" in the standard is used in conjunction with env 1070 mechanical safety terms. EN specifies the general safety rules and measures for all types of printing machinery, paper processing machinery, auxiliary equipment and machinery in the standard. The requirements of en to EN standards concerning the safety characteristics of a product shall take precedence over the corresponding provisions of en 1 according to the limit load of the test piece before the test. For printing machines not involved in en 1010 standard, relevant provisions in en standard can be adopted. However, the en standard alone cannot fully meet all the provisions of the machine. When conducting conformity assessment according to safety standards, corresponding supplements shall be made

in addition, in the absence of corresponding product safety standards for mechanical products, en mechanical safety - basic concepts, general principles of design - Part 1: basic terms, methodology, en mechanical safety - basic concepts, general principles of design - Part 2: technical principles and specifications, en 414 mechanical safety - Rules for drafting and expressing safety standards EN 1050 safety of machinery - risk assessment and other standards provide information for hazard analysis and assessment. Enterprises can analyze the possible hazards of products based on this. When taking appropriate measures, they need to pay attention to the full use of the issued Class B standards and the corresponding standards of Member States to ensure that the products meet the basic requirements specified in the regulations. If the standards issued by EU member states are used, they are only valid for the corresponding countries and can only be used for reference in other countries
