Functional safety of machine controls
The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this...
Safe drive controls with frequency inverters
Machine drives using closed-loop speed control are state of the art. As on drives without closed-loop speed control, the movement of a machine part at varying speeds frequently gives rise to a hazard against which the machine operators must be protected. The simplest means of preventing movements during manual intervention in danger zones is the (safe) disconnection of the energy driving the relevant motors. This is however often not possible, for example when intervention is required whilst the machine is running for the purpose of clearing faults, setup, during test operation, etc. Scenarios such as these require the machine to be operated with protective equipment disabled. In order for t...
Fire Retardancy of Polymeric Materials
The third edition of Fire Retardancy of Polymeric Materials provides a single source for all aspects of this highly challenging field of applied research. This authoritative book covers design and non-fire requirements that drive how these materials are fire protected. Detailed study and consideration of chemistry, physics, materials science, economic issues and fire safety science is necessary to address considerations of mechanical, thermal, environmental, and end-use requirements on top of fire protection means that the field requires. This thoroughly revised new edition continues to offer comprehensive coverage of the scientific approach for those developing fire safe materials. It cover...

Plastic Additives
Additives are essential components of plastic formulations providing maintenance and modification of polymer properties, performance and long-term use. The book provides information on the many different plastic ingredients and their purpose with market information, theoretical background such as mechanisms, state-of-the-art technical solutions, applications and examples, synergisms and antagonisms, risk and future trends covering plastics recycling and biobased products.
