Ansi B11; Machine Safety In Japan - Siemens SINUMERIK 840D sl Function Manual

Underwriter Laboratories Inc. (UL) has defined a special category for "Programmable Safety
Controllers" for implementing this requirement (code NRGF). This category covers control
devices that contain software and are designed for use in safety-related functions.
A precise description of the category and a list of devices that fulfill this requirement can be
found on the Internet at the following address:
NRGF → Online Certifications Directory → UL Category code/Guide information → search for
category "NRGF"
TUV Rheinland of North America, Inc. is also an NRTL for these applications.

ANSI B11

ANSI B11 standards are joint standards developed by associations such as the Association
for Manufacturing Technology (AMT) and the Robotic Industries Association (RIA).
The hazards of a machine are evaluated by means of a risk analysis/assessment. The risk
analysis is an important requirement in accordance with NFPA 79, ANSI/RIA 15.06, ANSI
B11.TR-3 and SEMI S10 (semiconductors). The documented results of a risk analysis can be
used to select a suitable safety system based on the safety class of the application in question.

Machine safety in Japan

The situation in Japan is different from that in Europe and the US. Legislation such as that
prescribed in Europe does not exist. Similarly, product liability does not play such an important
role as it does in the US.
Instead of legal requirements to apply standards have been defined, an administrative
recommendation to apply JIS (Japanese Industrial Standard) is in place: Japan bases its
approach on the European concept and uses basic standards as national standards (see table).
