1.1.2 Safety data
About this section
This chapter describes the necessary safety data required by standard EN ISO
13849-1:2015.
Prevailing directives and standards
For the use of industrial robots and how to protect personnel from being injured,
special regulations must be fulfilled as described in the following directives and
standards:
Performance level and category
EN ISO 13849-1, which is a B-standard, describes the general concept of
performance level (PL) and category. Each machine or machinery is potentially
dangerous and can cause personal injury. Based on severity of injury and probability
of accident, when using the machine, a certain level of safety performance, so
called required performance level (PLr) can be defined, where level a represents
the lowest risk and level e the highest. According to this, the machine must be
equipped with safety related parts, meeting the required performance level, to
reduce the risk to accepted low level. As specified in EN ISO 10218-1, normally
PL d is required for robots, but depending on the applications a higher requirement
could be needed if a risk analysis will result in PL e.
To comply with a certain PLr, in this case d, the safety related parts of the robots
and controllers must be structurally designed according to specific structure
categories and using reliable components.
In EN ISO 13849-1 it is in detail specified what category and components data,
which must be met, to fulfill PL d. These are:
Performance level for ABB IRC5 controller
To verify that robots and controller comply with at least PL d a self assessment
has been carried out and documented in a Technical Report. The essential
conclusions are accounted for below.
The safety related parts of robot and controller are e.g. the following stop circuits:
