Determining PFH, PFD, and MTTF

7.1

Single-channel operation

7.1.1

Determining PFD for single-channel operation

The value always refers to one internal safety relay (see assignment of outputs to the 
safety relay in Section "Terminal point assignment" on page 3-4).

This means that if several internal relays are used in a safety function, they should be 
considered with 1% each of SIL 2.

The logic has been taken into account within 1%.

PFD = 1% of SIL 2

 per internal safety relay

7.1.2

Determining PFH for single-channel operation

The value for PFH depends on the load for the contacts and the switching frequency.

In this section, the values are given for single-channel assignment, and these values only 
refer to one internal safety relay. This means that if several safety relays are used for a 
safety function, the values must be added together.

If the contacts of a safety relay have different loads, use the least favorable load for the 
calculation (see assignment of outputs to the safety relay in Section "Terminal point 
assignment" on page 3-4).

The value for PFH is determined using the following formula:

Where:

c

Switching frequency of the relay per hour [1/h]

b

Factor, see Table 7-1 [% x h]

PFH

Probability of Failure per Hour

PFD

Probability of Failure on Demand

MTTF

d

Mean time to dangerous failure

PFH = 0.01% + b x c

[% of SIL 2]
