This European Standard describes the health and safety requirements of fully automated plant used in the process
of tube forming, rolling and finishing (hereafter referred to as "plant"). It describes the foreseeable, significant
hazards, hazardous situations, and events arising from plants and from particular machines integrated to form the
plant; it does not describe the full health and safety requirements for each particular machine. It indicates
preventive measures for avoiding the hazards and reducing the risks. It deals not only with circumstances where
the machinery is used as intended, but also includes other conditions foreseen by the manufacturer, such as
foreseeable faults, malfunctions or misuse.
This European Standard specifies the requirements to ensure the safety of persons which are to be met during the
design, assembly, transport, commissioning, operation, maintenance and decommissioning of the equipment.
This standard assumes that installations are operated and maintained by adequately trained and competent
personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the normal use of
these machines.
This standard assumes that the machinery is used with adequate workplace lighting conforming to
!EN 12464-1" or to local regulations.
This standard applies to:
Automated plant and equipment operated for the production of metal seamless hot and cold finished tubes and
welded tubes. A list of machines which could make up different plants is shown in Annex D (informative).
This standard covers:
For seamless hot-finished tubes: from material charging downstream of the heating furnace through the rolling
process and up to, but not including any intermediate storage equipment or the downstream finishing lines.
For seamless cold-finished tubes: from material charging through the rolling process to the discharging
equipment but not including any storage equipment.
For welded tubes: from coil charging through strip preparation, forming and welding equipment up to, but not
including any intermediate storage equipment or the downstream finishing lines.
For the tube finishing line: from tube charging to the discharging equipment to the storage.
The following items are outside the scope of this standard:
? complete risk assessment of single machines which are used to form a plant
? furnaces;
? quenching equipment;
? spiral tube manufacture;
? large diameter tube welding manufacture using three-roll bending machines, U-ing and O-ing press
lines and their finishing lines;
? butt welding machinery for the manufacture of endless strips;
? irradiation units (material testing by e. g., ultrasonic and X-ray testing units);
? centrifugal casting machines;
? machine tools used for e. g., threading, chamfering, stamping and marking machines;
? storage equipment.
This standard does not establish any requirements concerning electromagnetic disturbances.
This standard is not applicable to tube rolling and forming mills and finishing line equipment, manufactured before
the date of publication of this standard by CEN.
