Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Inspection results shall be reported on equipment files and drawings.
5.3.2.2 Category I
This category involves observing the equipment during operation for indications of inadequate performance.
When in use, equipment shall be visually inspected on a daily basis for cracks, loose fits or connections,
elongation of parts, and other signs of wear, corrosion or overloading. Any equipment found to show cracks,
excessive wear, etc., shall be removed from service for further examination.
The equipment shall be visually inspected by a person knowledgeable in that equipment and its function.
5.3.2.3 Category II
This is Category I inspection plus further inspection for corrosion, deformation, loose or missing components,
deterioration, proper lubrication, visible external cracks, and adjustment.
5.3.2.4 Category III
This is Category II inspection plus further inspection, which should include NDT of critical areas and may
involve some disassembly to access specific components and to identify wear that exceeds the
manufacturer's allowable tolerances.
5.3.2.5 Category IV
This is Category III inspection plus further inspection for which the equipment is disassembled to the extent
necessary to conduct NDT of all primary load carrying components as defined by manufacturer.
Equipment shall be:
⎯ disassembled in a suitably equipped facility to the extent necessary to permit full inspection of all primary
load carrying components and other components that are critical to the equipment;
⎯ inspected for excessive wear, cracks, flaws and deformations.
Corrections shall be made in accordance with the manufacturer's recommendations.
Prior to Category III and Category IV inspections, all foreign material such as dirt, paint, grease, oil, scale, etc.
shall be removed from the concerned parts by a suitable method (e.g. paint stripping, steam cleaning, grit
blasting).
5.3.3 Frequency
5.3.3.1 Periodic inspection
The user/owner of the equipment should develop schedules of inspection based on experience, the
manufacturer's recommendations, and one or more of the following factors:

5.3.4 Inspection of remanufactured components
5.3.4.1 Unless specific and more stringent recommendations apply, welds of primary load carrying
components shall be inspected as follows:
a) immediately after grinding;
b) after welding, but no sooner than 24 h after the part has reached ambient temperature;
c) in service, after a period of time to be specified in the user/owner/manufacturer's procedures except
(unless otherwise recommended by the manufacturer) for non accessible inner parts remanufactured
under the full guarantee of the manufacturer.
5.3.4.2 The same NDT methods and procedures that detected the initial defects shall be used after
remanufacture. In the event of remanufacture of primary load carrying components by welding, at least two of
the most appropriate of the following methods shall apply with regard to 5.3.4.1 (b):
a) MT, for ferromagnetic materials, or PT, for non-ferromagnetic materials, to detect possible surface
defects;
b) UT to detect possible defects below the surface, or RT may be used as an alternative to UT if shown to
be at least as effective as UT on the same configuration;
c) proof load test in accordance with 8.3, followed by surface NDT of the tested component(s).
Other NDT techniques applied to hoisting and drilling equipment shall be submitted for the specific approval of
both user/owner and manufacturer.
5.3.5 Results of inspections
5.3.5.1 Acceptance criteria
Acceptance criteria shall be established based on experience and manufacturer's recommendations. Worn
equipment that does not meet the acceptance criteria shall not be accepted for operation.
5.3.5.2 Rejected equipment
Rejected equipment shall be marked and removed from service.
5.3.5.3 Surface indications
Surface indications identified by NDT may be allowable or non-allowable depending on their size, shape and
location, as defined by the manufacturer.
5.3.5.4 Allowable surface indications
Allowable surface indications are surface indications of such a size, shape and location that they need not be
removed.
5.3.5.5 Non-allowable surface indications
Non-allowable surface indications shall be classified as follows.
a) Minor surface indications – Minor surface indications may be removed by filing or grinding if this can be
achieved within the limits specified by the manufacturer, otherwise they shall be classified as major
surface indications. Caution should be exercised to prevent heating to an extent that could change the
mechanical properties, including toughness, of the material.
ISO/DIS 13534
b) Major surface indications – Major surface indications, which require material removal beyond the limits
specified by the manufacturer, should be corrected by remanufacture.
5.3.6 Inspection and maintenance (lubrication) of wire rope
Inspection and maintenance (lubrication) of wire rope used in hoisting shall be carried out on a regular basis.
API RP 9B may be consulted for further information on inspection and maintenance of wire rope.
6 Repair
6.1 Procedures
Manufacturers should provide adequate information to allow the equipment user/owner to identify the nature
of repairs that may be required. Repairs shall be performed using methods or procedures established in
accordance with 4.1.
6.2 Bearings
Anti-friction bearings play an important part in the serviceability of equipment. The most likely causes of the
need for bearing replacement are very loose or bent cages (rolling element retainers), corrosion, abrasion,
inadequate (or improper) lubrication and spalling due to fatigue. Excessive clearance may indicate improper
adjustment or assembly and should be corrected. Repair of anti-friction bearings should not be attempted by
field or shop personnel. The equipment manufacturer should be consulted in the event of unexplained or
repeated bearing failure.
6.3 Replacement parts
All replacement primary load carrying components shall meet or exceed the original manufacturer's criteria
and the following requirements:
a) the primary load carrying components shall be subject to the same minimum requirements and standards
as the original equipment components;
b) the documentation and traceability requirements shall be the same as for the original equipment
components.
7 Remanufacture
7.1 Procedures
Remanufacture of equipment shall be performed using methods and procedures developed in accordance
with 4.1. The material used for the remanufacture shall be qualified to the manufacturer's requirements for
mechanical properties, ductility and toughness. The equipment rating resulting from remanufacture should be
in accordance with the equipment manufacturer's recommendations. Equipment that cannot be
remanufactured shall be destroyed.
If welding is necessary, it shall be performed in accordance with a written procedure that has been qualified in
accordance with a recognized standard.
7.2 Verification
Following remanufacture, verification shall be performed in accordance with 5.3.4.

ISO/DIS 13534
8 Load testing
8.1 General
Two types of load test are described in this International Standard, as follows in 8.2 and 8.3.
8.2 Performance load test
A performance load test may be used to verify the function of the equipment and/or its ability to perform under
specific conditions or in conjunction with other equipment or materials (e.g. it may be used to determine the
effects of gripping a specific pipe with a given elevator). A performance test may consist of any number of
cycles (as needed) of loads up to, but not exceeding, the rated load of the equipment under test.
8.3 Proof load test
A proof load test is performed by applying a load equal to 1,5 times the rated load of the equipment for a
period of not less than 5 min. Proof load tests should not consist of more than one cycle and shall not be used
in lieu of performance load tests. Hoisting equipment and drilling equipment (as applicable) should be proof
load tested only once following manufacture or remanufacture, since loads above the rated load may cause
cumulative (fatigue) damage. A proof load test shall be followed by surface NDT. Materials that are prone to
delayed cracking should be subjected to surface NDT no earlier than 24 h after proof load testing.
9 Documentation and records
9.1 General
The user/owner shall maintain an equipment file containing pertinent information regarding the equipment.
The equipment file should include the following:
a) documentation delivered by the manufacturer;
b) documentation established by the user/owner during the life of the equipment.
9.2 User/owner equipment file
