Introduction
This European Standard has been prepared to be a harmonized standard to provide one means of complying
with the essential safety requirements of the Machinery Directive and associated EFTA regulations.
The extent to which hazards are covered is indicated in the scope. In addition, lifting equipment shall conform
as appropriate to !EN ISO 12100" for hazards which are not covered by this standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for equipment
that have been designed and built according to the provisions of this type C standard."
1 Scope
This Part of EN 818 specifies the requirements related to safety, methods of rating and testing of single-, two-,
three-, four-leg and endless chain slings, assembled by welding, using short link grade 4 medium tolerance
chain conforming to !EN 818-3:1999+A1" together with the appropriate range of components of the same
grade in accordance with !EN 1677-5:2001+A1" and !-6:2001+A1". These chain slings are intended
for lifting objects, materials or goods.
NOTE Instructions for use and maintenance of chain slings are covered by !EN 818-6:2000+A1".
The hazards covered by this Part of the standard are identified in clause 4.
Annex A gives an alternative method of rating and marking a chain sling for a specific lifting application.

4 Hazards
!Accidental release of a load, or release of a load due to" failure of lifting accessories such as chain
slings or their component parts puts at risk either directly or indirectly the safety or health of those persons
within the danger zone of lifting equipment.
In order to provide the necessary strength and durability of lifting accessories this Part of EN 818 lays down
requirements for the design, manufacture and testing to ensure that specified levels of performance are met.
Fatigue failure has not been identified as a hazard when chain slings having the specified levels of
performance given in this Part of EN 818 are used in general lifting service.
Since failure can be caused by the incorrect choice of grade and specification of lifting accessories this Part of
EN 818 also gives the requirements for marking and the manufacturer's certificate.
Errors in fitting together of welded chain slings can also lead to premature failure and this European Standard
contains dimensional requirements to allow correct fit.
Those aspects of safe use associated with good practice are given in !EN 818-6:2000+A1".
Table 1 contains those hazards, which require action to reduce risk identified by risk assessment as being
specific and significant for chain slings grade 4.

Annex A
(normative)
A.1 General
The rating of a chain sling used for a specific application is given in A.2 and may be used as an alternative to
the method of rating given in 5.3.
The chain sling shall be rated at a working load limit according to the particular angle of the legs to the vertical
at which the chain sling is to be used. The manufacturer shall ensure that the master link selected possesses
mechanical properties appropriate to the application.
For two-leg chain slings used at an angle β to the vertical, the working load limit (WLL), in tonnes, shall be as
given by the following formula:
For three-leg chain slings used at an angle β of any leg to the vertical, the working load limit (WLL), in tonnes,
shall be as given by the following formula:
For four-leg chain slings used at an angle β of any leg to the vertical, the working load limit (WLL), in tonnes,
shall be as given by the following formula:
NOTE This assumes that there is an equal distribution of the load between each leg.

(informative)
B.1 Calculated values of working load limit (WLL) for single-leg chain slings
!The calculated values for the working load limits are based on the following equation:"
2 × ¼ × π × 100 × d n

WLL =
g × 1000
where:
!The calculated values have been rounded down to the nearest lower value of the R40 series of preferred
numbers in accordance with ISO 497. These values are listed in Table 2 column 2."
B.2 Calculated values of working load limits (WLL) for multi-leg chain slings
!The calculated values for the working load limits are based on the equation for the single-leg chain sling
multiplied by the appropriate factor given in Table 2. They have been rounded down to the nearest lower value
of the R40 series of preferred numbers in accordance with ISO 497. These values are listed in Table 2
columns 3 to 7."
e.g. for the 22 mm nominal size the calculated WLL = 7,752 × 1,4 = 10,85
