Annex A
(informative)
Guidance to assist the manufacturer to prepare documented information
for the use and maintenance of chain slings
A.1 Use of chain slings
A.1.1 Chain sling selection
A.1.1.1 General
The relevant Parts of EN 818 and EN 1677 define working load limit using the term General Lifting Service.
This reflects the fact that lifting accessories can be and are used in a wide variety of circumstances in terms of
configuration, types of load, methods of attachment. Design considerations and working load limit ratings are
given in the relevant Parts of EN 818 and EN 1677 take account of these circumstances.
!EN 818-4:1996+A1" and !EN 818-5:1999+A1" permit an alternative method of rating where a chain
sling is to be used exclusively for a single specific lifting application where all of the circumstances of use are
known.
A.1.1.2 Use in adverse environments
A.1.1.2.1 High and low temperature conditions
Care should be taken to take account of the maximum temperature which can be reached by the chain sling in
service. This is difficult in practice but underestimation of the temperature involved should be avoided. Table
A.1 summarizes the necessary variation in WLL due to temperature.
Chain slings of Grades 4 and 8 will not be adversely affected by temperatures down to -40 °C and no
reduction from the working load limit is therefore necessary on this account. Where chain slings are to be
used at temperatures below -40 °C, the manufacturer should be consulted.
1)
Table A.1 — Variation in working load limit due to temperature
Grade Working load expressed as a percentage of working load limit
Temperature, t, °C
-40 < t ≤ 200 200 < t ≤ 300 300 < t ≤ 400 400 < t ≤ 475 !t > 475"
4 100 100 75 50 Not permissible
8 100 90 75 Not permissible
1)
The use of chain slings within the permissible temperature ranges given in the table does not
require any permanent reduction in working load limit when the chain is returned to normal
temperatures. If chain slings reach temperatures in excess of the maximum permissible
temperatures indicated in the table, they should be withdrawn from service and referred to the
manufacturer.

---------------------- Page: 9 ----------------------
EN 818-6:2000+A1:2008 (E)
A.1.1.2.2 Acidic conditions
A.1.1.2.2.1 Chain slings of grade 8
Chain slings of Grade 8 should not be used either immersed in acid solutions or exposed to acid fumes.
Attention is drawn to the fact that certain production processes involve acidic solutions and fumes and in these
circumstances the manufacturer's advice should be sought.
For the same reasons chain slings should not be galvanized or subjected to any plating processes without the
approval of the manufacturer.
A.1.1.2.2.2 Chain slings of grade 4
Chain slings of Grade 4 may be used in acidic conditions. The following precautions should be adopted:
a) the working load of such a chain sling should not be greater than 50 % of the working load limit;
b) the chain sling should be thoroughly washed in clean water immediately after use;
c) the chain sling should be given an inspection by a competent person each day before use.
A.1.1.2.3 Conditions in which the chain sling is likely to be subjected to attack (chemical, abrasive
etc.)
The manufacturer of the chain sling should be consulted, particularly if the chain sling is to be exposed to
highly concentrated chemicals combined with high temperatures.
A.1.1.3 Use in exceptionally hazardous conditions
The rating of lifting accessories in European Standards assumes the absence of exceptionally hazardous
conditions. Exceptionally hazardous conditions include offshore activities, the lifting of persons and lifting of
potentially dangerous loads such as molten metals, corrosive materials or fissile materials. In such cases the
degree of hazard should be assessed by a competent person and the working load limit adjusted accordingly.
A.1.2 Chain sling verification before first use and in service
A.1.2.1 Before first use
Before first use of the chain sling it should be ensured that:
a) the chain sling is precisely as ordered;
b) the manufacturer’s certificate is to hand;
c) the identification and working load limit marking on the chain sling correspond to the information on the
certificate;
d) full details of the chain sling are recorded.
A.1.2.2 Before each use
Before each use the chain sling should be inspected for obvious damage or deterioration (see A.2.1). If faults
are found during this inspection, the procedure given in A.2.1 should be followed.

EN 818-6:2000+A1:2008 (E)
A.1.3 Handling the load
A.1.3.1 Preparation
Attention should be given to any specific instructions provided for the handling of the load. Before starting the
lift, it should be ensured that the load is free to move and is not bolted down or otherwise obstructed.
A.1.3.2 Mass of the load
It is essential that the mass of the load to be lifted is known. If the mass is not marked the information should
be obtained from the consignment notes, manuals, plans etc. If such information is not available the mass
should be assessed by calculation.
A.1.3.3 Centre of gravity
The position of the centre of gravity of the load should be established in relation to the possible points of
attachment of the chain sling. To lift the load without it tilting or toppling the following conditions should be
met:
a) For single leg and endless chain slings the attachment point should be vertically above the ce
