2.3. Scale washing
Weighing platforms are made of stainless steel (according to standards
PN–0H18N9, EN-1.4301, AISI–304) and silicon elements.
There is an exception, zinc coated overhead scales and painted livestock
scales made of mild constructional steel with aluminium cover plate on
the platform, polyester overlays and stainless steel or polyamide glands.
Caution:
Washing and disinfection agents should be matched to the scale.
Platforms of ramp and livestock scales as well as load-bearing structures
and weighing tracks of overhead scales can be washed with jet of water (temp.
up to +80°C) with an appropriate washing agent. Washing measuring indicators
/ weighing indicators with the jet of hot water is not allowed.
Caution:
It is advisable to cover measuring indicators/weighing indicators
while washing their surrounding with the jet of water.
To wash waterproof platform scales and indicators neither jet of water nor hot
water shall be used, in order not to damage the silicon gaiter that covers the
load cell inside the platform and the overlay or glands in the indicator. To wash
pans of platform scales they should be taken off first. Then they can be washed
ether with the jet of water or by immersion.
