AS 4024-1 Safeguarding of Machinery

• Brief summary of detail:

– EN 1070 Terminology– Definitions – Common tri-lingual terms

– ISO 12100.1 Basic terminology and methodology

– Description of Hazard and Risk and Risk Control Principles – Hierarchical structure.

– ISO 12100.2 Technical principles– Descriptive design application of Part 1

AS 4024-1 Safeguarding of Machinery

– ISO 14121 Principles for Risk Assessment

– Development of the risk assessment principles introduced in ISO 12100 – 1

– EN 626.1 Reduction of risks from hazardous substances emitted by machinery

– Expansion of principles from ISO 12100 – 1

– EN 614.1 Ergonomic design principles.– General principles related to MSD and broader

ergonomics e.g. displays & signals, actuators

AS 4024-1 Safeguarding of Machinery

– ISO 13849.1 Safety related parts of control systems – design

– Selection of categories– Fault consideration, fault exclusion– Validation – validation plan and report– Maintenance

– ISO 13849.2 Safety related parts of control systems – validation

– Validation by analysis – FTA, ETA, FMEA, – Validation by testing– Validation tools – informative tables of faults and principles for

fault exclusion.

AS 4024-1 Safeguarding of Machinery

AS 4024-1 Safeguarding of Machinery

– ISO 14120 Design and const. of fixed and moveable guards

– ISO 14119 Selection of interlocking devices– ISO 14118 Prevention of unexpected start-up– ISO 13850 Emergency stops

– Generally in line with the current standard. ISO 14118 is a little more extensive and the specific detail in the current standard relating to lanyard E-stop devices is not included in ISO 13850

AS 4024-1 Safeguarding of Machinery

– ISO 7250 Basic human body measurements

– EN 547.1 Dimensions required for whole body access into machinery

– EN 547.2 Dimensions for access openings– EN 547.3 Anthropometric data

• All new material related to the need to access machinery, plant and equipment as opposed to the following section which deals with prevention of access.

AS 4024-1 Safeguarding of Machinery

– ISO 13852 Safety distances – upper limbs

– ISO 13853 Safety distances – lower limbs– ISO 13854 Minimum gaps to prevent

crushing

– Virtually identical material to current standard. Minor variations in safety distances – conservative. Safety distances based on Anglo/Saxon (middle European) data, lower end uses 5th percentile 14 yr old female.

AS 4024-1 Safeguarding of Machinery

– EN 894.1 Displays and control actuators –principles for human interaction

– New material covering ergonomic principles

– ISO 9355.2 Displays – design– New material – visual, digital, analogue and tactile

displays – use of scales, pointers, perception, discrimination

– EN 894.3 Control actuators – design– New material – design and shape of manually

operated actuators relative to shape, transmission of force, posture

AS 4024-1 Safeguarding of Machinery

– IEC 61310.1 Req’ts for visual, auditory and tactile signals

– IEC 61310.2 Visual, auditory and tactile signals -marking

– IEC 61310.3 Location and operation of actuators

– ISO 11429 Auditory and visual danger and information signals.

– New material covering ergonomic principles – brightness, contrast, colour, symbols, marking e.g specification plates, rated values, correlation between actuation and final effect, quality and distinction for purpose in auditory and visual signals

AS 4024-1 Safeguarding of Machinery

• Potential Impacts

– Incorporation of ISO 13849.1 & 2 – Fault exclusion, Functional Spec. & Validation

– Emphasis on displays, control actuators, and visual, auditory and tactile signals.

– Users familiar with current standard will need to spend some time in reorientation regards content and expression
