How do shock indicators work?
Shock indicators are used to monitor a product during shipping. Shock indicators are triggered when a shock exceeds a certain impact force.
Impact indicators consist of a strong adhesive sticker with a glass tube in a plastic casing. There are various defined impact forces (see table). If these are exceeded, the surface tension of the warning fluid breaks, and the indicator turns permanently red. The impact forces are indicated by the G-value. G-forces are the stresses that act on an object or vehicle due to a sharp change in the magnitude and/or direction of speed.
This allows the customer to clearly see upon delivery whether the product has been improperly handled. Each shock indicator has its own serial number to prevent subsequent replacement.
The customer should check the impact indicators before acceptance and accept the delivery even if discoloration is detected. The discoloration should be noted on the delivery documents and confirmed by the freight forwarder on the waybill. Only then can the customer claim compensation in the event of damage.
Determination of the indicator
To select the correct impact indicator, the package size in cubic meters is calculated using the formula L x W x H (in meters) and read off in the top row of the table. The total weight including packaging in kilograms is read off in the left column. The resulting color field then defines the optimal indicator for this packaging.
Always attach impact indicators on the long side of the packaging towards the corner of the packaged goods.
