AS/NZS 4024.3202:2021 pdf free.Safety of machinery Part 3202: Plastics and rubber machines – Injection moulding machines – Safety requirements (ISO 20430:2020, MOD).
4 Safety requirements and/or protective/risk reduction measures
4.1 Basic requirements
4.1.1 General
Machinery shall comply with the safety requirements and/or protective/risk reduction measures of this clause. In addition, the machine shall be designed in accordance with the principles of Iso 12100:2010 for relevant but not significant hazards, which are not dealt with by this document.
Protective systems and safety-related parts of the control systems shall be in accordance with:
— Protective Type I, II and Ill as specified in Annexes B. C and D. These annexes describe minimum requirements and the calculation of the PL of the whole system achieved is not required; or
— the PLr in accordance with ISO 13849-1:2015, as specified in the relevant subclauses.
NOTE The safety level achieved when applying the PLr as specified in the relevant subclauses is at least equivalent to the safety level achieved when applying the annexes.
4.1.2 Start, stop and restart functions Start function
The start of an operation shall be possible only when all safeguards are in place and functioning (see IEC 60204-1:2016, The machine shall only be started by actuation of the start device provided for that purpose or closing a control guard in accordance with 4.2A. Stop function Normal stop
The machine shall be equipped with a control device activating a stop function in accordance with stop category 0 or 1 as described in IEC 60204-1:2016, 9.2.2. that brings the machine to a complete stop. OperatIonal stop
For operational reasons, e.g. to permit an easier and more rapid restart of the machinery, it could be necessary to provide a stop control that does not cut off the energy supply to the actuators.2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 7345, Thermal insulation — Physical quantities and definitions
ISO 13370, Thermal performance of buildings — Heat transfer via the ground — Calculation methods ISO 52000-1:2017, Energy performance of building — Overarching EPB assessment — Part 1: General framework and procedures
ISO 52010-I, Energy performance of buildings — External climatic conditions — Part 1: Conversion of climatic data for energy calculations
ISO 520 16-1, Energy performance of buildings Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads — Part 1: Calculation procedures
NOTE I Default references to EPH standards other than ISO 52000-1 are identified by the EPB module code number and given in Annex A (normative template in Table A.i) and Annex B (informative default choice in Table B.1).
EXAMPLE EPH module code number: MS—S. or M5-5,1 (if module MS—S is subdivided), or MS—S/i (if reference to a specific clause of the standard covering M5—5).
NOTE 2 In this document, there are no choices in references to other EPH standards. The sentence and note above is kept to maintain uniformity between all EPB standards.
In this case, in addition to the above normal stop function, a stop category 2 may be used for the movements in the areas which are enclosed by safeguards which are in place and functioning. When a safeguard is activated, stop category 0 or 1 shall become effective as specified in the relevant subclauses. Interruption or failure of the power supply
An interruption or a failure of the power supply shall not result in a loss of safety function and restoration of the energy supply shall not result in the automatic restarting of the machine (see ISO 12100:2010, and
4.1.3 Emergency stop
The emergency stop shall function as a category 0 or 1 stop as described in IEC 60204-1:2016, 9.2.2 ensuring the fastest stopping.
Emergency stop devices shall be in accordance with ISO 13850:2015 and IEC 60204-1:2016, 10.7. An emergency stop device shall, at a minimum, be located at each operator station.
Actuation of an emergency stop device shall stop any dangerous movement and shall discharge the hydraulic accumulators.
In addition, the actuation of emergency stop devices shall stop the supply of the following unless their continued supply is necessary to prevent further hazards such as overheating/overpressure when processing materials which can lead to degradation (e.g. PVC):
— power to the cooling/heating elements;
— gas/water.
See 6.2.2.
4.1.4 Guards Common requirements
Guards shall be designed in accordance with ISO 14120:2015.
Safety distances for distance guards, enclosing guards, and interlocking guards shall be in accordance with the following unless otherwise specified in this document:
— ISO 13857:2008, Table 1 for reaching over protective structures;
— ISO 13857:2008, Table 3 for reaching around with limitation of movement;AS/NZS 4024.3202 pdf download.
