Introduction
This European Standard is a type C standard as stated in EN ISO 12100.

The machinery concerned and the extent to which hazards are covered are indicated in the scope of this

standard.
It is assumed that:

a) discussions take place between the manufacturer/supplier and purchaser/hirer about specific local

installation conditions and expected duty;

b) a risk analysis for each component that might be incorporated into a complete SAE installation has been

made and rules have been drawn up;

c) the safety requirements of this standard have been drawn up on the basis that the components are:

1) designed in accordance with good engineering practice and calculation codes, including all failure

modes;
2) of sound mechanical and electrical construction;
3) made of materials with adequate strength and of suitable quality;
4) free of visible defects;
d) harmful materials such as asbestos are not used;
e) the equipment is maintained in good working order;

f) any mechanical device manufactured in accordance with good practice and the requirements of this

standard shall not be allowed to deteriorate to the point of creating a hazard without being detected;

g) the working ambient temperature range is between –10 °C and +55 °C;

h) the structure on which the SAE is installed is of adequate strength to resist the expected imposed loads.

When provisions of this type C standard are different from those which are stated in type A or B standards, the

provisions of this type C standard take precedence over the provisions of the other standards, for machines

that have been designed and built in accordance with the provisions of this type C standard.
