This document includes safety requirements for the design and installation of equipment that is intended for storage, handling and transportation of flat glass outside the factory. It applies to machinery within in the scope of EU Directives as well as to equipment that is covered by non-harmonized documents.

1.2     This document specifies safety requirements for the following equipment for storage (see 3.2.1), handling (see 3.2.2) and transportation (see 3.2.3) of flat glass outside the factory (see 3.1.1):

—    vehicle-mounted frails with motorized adjustment of the angle of lean for loading and unloading, which are used for road transport;

—    inloader vehicles for road transport outside the factory, where loading and unloading is only made on virtually horizontal and sufficiently stable grounds that are free of significant irregularities;

—    specific self-propelled equipment for securing the glass (inloader load-securing systems);

—    equipment for picking up single glass plates, firmly-attached glass plates or glass packs for transportation between different locations where the retention force or lifting force is generated by engine power.

1.3     This document specifies additional requirements for the following equipment that is not covered by EU Directives:

—    vehicle-mounted frails without an adjustable angle of lean for loading and unloading, which are used for road transport;

—    movable storage equipment designed to transport the glass outside the factory (e.g. inloader stillages, see Figure C.6);

—    glass-securing devices or systems for transport stillages (e.g. spring tensioning rods, stanchions).

NOTE         Specific hazards due to the use inside the factory are dealt with in EN 13035‑1.

1.4     This document deals with road transport as wells as rail transport.

1.5     This document only deals with equipment which is in direct contact with the glass. This document does not apply to manual handling equipment such as carrying straps and manual vacuum lifting devices and to all packaging for glass which always opened and closed in the factory (see EN 13035‑1). Tractors, cranes, hoists and forklift trucks as well as elements of self-propelled vehicles, which are not in contact with the glass, are out of the scope. This document does not apply to the transport of glazed windows/frames, neither does it apply to equipment for different transportation than on road or on rail, e.g. by ships.

1.6     This document deals with all significant hazards, hazardous situations and hazardous events, which are relevant to equipment for storage, handling and transportation of flat glass, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex B). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during commissioning, operation and maintenance. Noise hazards have not been considered significant for any type of equipment within the scope of this document.

1.7     This document does not apply to equipment for storage, handling and transportation of flat glass outside the factory, which is manufactured before the date of publication of this document as EN.

            This document includes safety requirements for the design and installation of equipment that is intended for storage, handling and transportation of flat glass inside the factory. It also applies to equipment within the scope of EU Directives as well as to equipment that is covered by non-harmonized documents. Annex E gives an overview of the differentiation.

1.2     This document specifies safety requirements for the following equipment:

—    equipment for storage provided with elements that are propelled by a drive system other than directly applied human or animal power (engine power) in order to store or retrieve glass in or from storage shelves or frames (see 3.2.2);

NOTE          Additional requirements covering specific hazards that are resulting from the use outside the factory are dealt with in EN 13035‑2.

1.4     This document only deals with equipment which is in direct contact with the glass, with the exception of wooden packaging. Tractors, cranes, hoists and forklift trucks as well as elements of self-propelled vehicles, which are not in contact with the glass (see 3.4.1), are out of the scope. This document does not apply to equipment for picking up single plates, such as manual vacuum lifting devices, lifting straps or other manual devices. This document does not cover automatic loading or unloading of storage and transportation equipment. This is covered in EN 13035‑5.

1.5     This document deals with all significant hazards, hazardous situations and hazardous events, which are relevant to equipment for storage, handling and transportation of flat glass, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex D). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during commissioning, operation and maintenance. Noise hazards have not been considered significant for any type of equipment within the scope of this document.

1.6     This document is not applicable to equipment for storage, handling and transportation of flat glass inside the factory, which is manufactured before the date of publication of this document by CEN.

This part of ISO 13849 specifies a methodology and provides related guidance for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. This document specifies the characteristics needed to determine the performance level required of safety functions. This document applies to SRP/CS for high demand and continuous mode including their subsystems, regardless of the type of technology and energy (e.g. electrical, hydraulic, pneumatic, mechanical), for many kinds of machinery. The standard does not apply to low demand mode.

This document does not specify the safety functions or required performance levels that are to be used in particular applications.

This document does not give specific requirements for the design of products that are parts of SRP/CS.

This document does not provide specific measures for security (e.g. physical, IT-security, cyber security) aspects.

NOTE 1   This document specifies a methodology for SRP/CS design without considering if certain machinery (e.g. mobile machinery) requires specific requirements. These specific requirements can be considered in a Type‑C standard.

NOTE 2   See IEC 61508 for low demand mode.

NOTE 3   See also ISO/TR 22100‑4 for IT-security aspects and IEC/TR 63074 for security aspects.

This part of ISO 16890 specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.

It is intended for use in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4.

The test method described in this part of ISO 16890 is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24,0 inch × 24,0 inch).

ISO 16890 (all parts) refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within ISO 16890 (all parts).

NOTE          The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it will be very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.

Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods, (see ISO 29463 (all parts)).

Filter elements used in portable room-air cleaners are excluded from the scope.

The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.
