1.  INTENDED USE  

 

Frames for HX5.EX… scales are intended for operation either inside or outside 
the building. Avoid exposing them to aggressive chemical vapours and extreme 
temperatures.  
Frames for HX5.EX-tt.4.xx.C… scales are made of powder coated steel and 
frames for HX5.EX-tt.4.xx.Hy/Z… scales are made of stainless steel. 

 

The difference in used material influences their intended use in a specific 
hazardous area:  

  frames made of powder coated steel can be used in zones 

1 and 2

 where 

there is a risk of explosion due to mixture of air with vapour, mist or gas, 
classified as explosion group 

IIB and IIA 

and as temperature class 

T1, T2, 

T3, T4

  frames made of stainless steel can be used in zones 

1 and 2

 where there 

is a risk of explosion due to mixture of air with vapour, mist or gas, 
classified as explosion group 

IIC, IIB and IIA 

and as temperature class 

T1, 

T2, T3, T4

. It can also be used in zones 

21 and 22 

where there is a risk of 

explosion due to mixture of air with dust, flammable fibres and volatile 
fuels, classified as explosion group 

IIIC, IIIB and IIIA

 

 

 

Platform with frame 

 

 

The frame may be used as a component of device/set intended 
for operation in hazardous area. Intended use of the whole set 
is determined by the component with the lowest explosion 
protection. The set can be used in more restricted zones than 
specified for the frame.
