Discard criteria for AGON flat webbing and round slings

If one or more of the following faults is established, the sling must be taken out of service.

1) Missing label

The standards and local regulations stipulate that specific data, including maximum load, shall be stated on the label. The label must therefore be intact.

2) Date expired

– or lack of date marking.

The most recent mandatory annual inspection date must be stated on the sling at all times. If the sling is new, it is not necessary to label it with the commissioning date if the production date is less than 12 months before the commissioning date. If the sling has a QR code, you may be able to download the production date and possibly the commissioning date by electronic means.

If the sling is labelled with a specific year colour:

  • 2018 Blue
  • 2019 Red
  • 2020 Green
  • 2021 Gul
  • 2022 Blue
  • 2023 Red
  • Etc.…

White means discarded.

3) Cuts or stretching

For flat straps:

If any part of the sling is cut across more than 5% of its width, it must be discarded.

All the examples shown here must be discarded:

4) Contaminated with chemical substances

Some chemical substances degrade polyester fibre. If you are in doubt which substance the sling is contaminated with, discard the sling. Most oil-based products, including anti-corrosion protection products for steel, do not cause degradation. If the sling is saturated or dark in colour, it must be discarded.

5) Solar UV degradation

The slings are made of a plastic material that, like most plastics, is subject to solar UV degradation. f the sling is dyed, the dye pigment will degrade before the sling itself. This means that you can use the sling if the colour is not completely faded. Eg. a purple or green strap should be purple or green not nearly white.

6) Knot on the strap

The sling must not be knotted. You may be tempted to knot the sling, e.g. to shorten it. Never knot a sling as knotting destroys the fibres, due to the heat caused by friction when you use a knotted sling to hoist a load.

7) Welding spray

If there is welding spray on the sling, it must be discarded if these in some places make up more than 5% of the width of the strap.

The example shown must be discarded.

8) Heat exposure

If the strap has melted completely or partially due to heat, it must be discarded.

The example shown must be discarded.

9) Wear marks

If the strap has melted due to abrasion resistance, so that the molten material in some places constitutes more than 5% of the width of the strap, it must be discarded.

The example shown must be discarded.

10) Acid burnt

If the strap has been exposed to acid or base, so that the fibers are burnt somewhere, it must be discarded.

The example shown must be discarded.

11) AGON Reinforced

For round slings:

There must be no holes in the sling. However, the outer layer in a round sling may be torn or cut through. This applies only to AGON-standard, double cover slings. The white core fibres must not be visible. If round slings are used in environments with gravel, sand and other abrasive materials, a sling with holes in it must be discarded because the abrasive materials can erode the fibres from the inside.

If the white fibers are visible, the round sling must be discarded, see picture below:

  3. The outer wear bag that may be damaged if the inner bag is intact

If in doubt, ask your supervisor!

REMEMBER! When you put the hook in the strap, you take responsibility for everything is OK.

NEVER use straps with a date that is over 12 months old.

Remember to hang the strap up after use, check it when you still have it.

If the strap is bleached, it is because it is broken down by the sun’s rays, so it must not be used.

When you scan the QR code on the straps, more information is available.
