Why safety in packaging / printing?

PROCESS RELIABILITY

• access causes immediate stopof related machine parts

- safety position switches- safety switches- safety sensors

• access prevented while processin progress

- solenoid door interlocks

External disturbance of (packaging) processes may cause failures up to fatal line breakdowns

- Partial damages

- Maintenance invest

- Production losses

- Poor output quality due toimproper working machine

Usage of safety components ensuressafe processes in order to keep costsat a minimum

Requirements on Safety of Machinery

• Subject of national law with different requirements, may bein form, may be in content

• Different requirements in e.g. China, USA, European Community etc.

• Requirements can be addressed to machine manufacturesor to machine users or to both of the parties

• E.g. European Community: Addressed (first of all) to machinemanufacturers by so-called EC’s Council Directive

• Although meanwhile there is a lot of International Standardization

Safety basics

08.08.2008 - VE/JSCH

• Contribution to a mutual (global) understanding of the contentsof requirements (Global Regulatory Product Compliance)

• But – may be – there are still additional dissent national requirements

• Further: Formalities of bringing into circulation may be still different, e.g. mandatory and non-mandatory product certifications

Function of International Standardization

Safety basics

International Standardization

• Made by ISO (International Standardization Organization);standards of basics, safety aspects, safeguards of machinery

• Made by IEC (International Electrical Committee);standards of safety-related electrical matters

• Replacing more and more (but not yet completely) other(national or regional) standards (e.g. CEN, CENELEC etc.)

Type B1Safety aspects

Type B2Product specificsafety equipment

Type C

Type A Contain basic terms, design principles and general aspects which apply to all machines, linked machines, parts of machines and safety components due to the field of applicationmentioned in the Machine Directive.

Type B1 Contain definite statements and possible solutions to general level safety aspects dealt within the basic standard, e.g. safety distances, surface temperature, noise, safety relatedcontrol systems.

Type B2 Contain definite statements or possible solutions to safety-related fixtures, e.g. two-hand-controls, interlocking devices, and separating guard devices.

Type C Contain definite requirements or protective maesures for typical hazards which arise with a machine or group of machines, e.g. machine tools, rubber and plastic processing machines, packaging machines, machines for foodstuffs, woodworking machines, constructionmachines.

(Harmonised) Norms Reference for Schmersal products

EC Directives

Implementationin national law

• Machinery Directive

• Low Voltage Directive

• Electromagnetical Compliance

• EN 954-1 Safety of machinery - Safety-related parts of control sy stems

• EN 1088 Safety of machinery - Interlocking devices associated wi th guards

• IEC 60947 Low-voltage switchgear and controlgear

The intention of the hamonisation concept is that EC Directivesand their annexes should only contain essential safety require-ments. The binding, but normally very general essential safetyRequirements, should be supplemented by harmonised, non-binding European standards.

Risk assessment to ISO EN 13 849-1:2006

Safety basics

RequirementsThe safety-related parts of control systems and/or their protective equipment and their components must be so arranged, built, selected, assembled and combined in accordance with the applicable standards that they are able to withstand the influences to be anticipated.

System behaviourThe occurrence of a fault can lead to the loss of the safety function.

Principles to achieve safetyMainly characterised by the selection ofcomponents

Safety basics

Risk assessment ISO EN 13 849-1

RequirementsThe requirements of B must be fulfilled. Proved components and safety principles must be applied.

System behaviourThe occurrence of a fault can lead to the loss of the safety function. The probability of a fault occurring is lower than in Category B.

RequirementsThe requirements of B and the application of proved safety principles must be fulfilled. The safety function must be tested by the machine control system at suitable intervals.

System behaviourThe occurrence of a fault can lead to loss of the safety function in the interval between tests. The loss of the safety function is detected by the test.

Safety basics

Risk assessment ISO EN 13 849-1

RequirementsThe requirements of B and the application of proved safety principles must be fulfilled. Safety-related parts must be arranged such that: A single fault in each of these parts does not lead to loss of the safety function and: Whenever this can be carried out in an appropriate manner, the individual fault should be detected.

System behaviourIf an individual fault occurs, the safety function is always maintained. Some but not all faults are detected. An accu-mulation of undetected faults can lead to loss of the safety function.

RequirementsThe requirements of B and the application of proved safety principles must be fulfilled. Safety-related parts must be arranged such that: A single fault in each of these parts does not lead to loss of the safety function and: The individual fault is detected on or before the next requirement of the safety function. If this is not possible, an accumulation of faults must not lead to loss of the safety function.

System behaviourIf faults occur, the safety function is always maintained. The faults are detected in time to prevent a loss of the safety function.
