Standards We Use

The standards we consider for your assessment and mitigation

The list of modern safety standards is constantly changing and updating and it can be very imposing to keep up to date and informed. Sentinel Machine Safety provides step by step assistance in choosing what standard or standards apply to each project. A very large portion of situations can be accounted for with the following four standards:

ISO 12100: Risk Assessment and Risk Reduction

Specifies principles of risk assessment and risk reduction to help designers in achieving safe design of machinery. These principles are based on knowledge and experience of the design, use, incidents, accidents, and risks associated with machinery.

ISO 13849-1: General Principles for Design

Provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems, including the design of software.

ISO 13849-2: Validation

Specifies the procedures and conditions to be followed for the validation by analysis and   testing of specified safety functions, category achieved, and performance level achieved.    This standard is used primarily during the on-site validation portion of Sentinel’s services.

IEC 62061: Functional Safety

Specifies and makes recommendations for the design, integration and validation of safety-related electrical, electronic, and programmable electronic control systems.

ANSI B11 Standards

The ANSI B11 series of American National Standards and Technical Reports consists of nearly three dozen different documents that deal with machine / machinery / machine tool safety, and they specify requirements for both the manufacturers (suppliers) and users of the machines. The list continues, and the total number of specific standards is quite staggering. The specific standards can be extremely narrow, such as ANSI/RIA R15.06 which focuses on the safety of personnel who work in close proximity to industrial robotics, or they can be broader based while still focusing on a specific aspect of manufacturing such as ISO 13574 which deals with industrial furnaces and related equipment. Sentinel Machine Safety is equipped to work within any relevant safety standards in order to provide the best and safest result for each new project.

International Standards

The proliferation of PLC controls over the past two decades has resulted in a number of new international standards specific to machine control. These standards include ISO 13849, IEC 62061, and ANSI B11. Sentinel Machine Safety was created to help our clients achieve a ‘Due Diligence’ level of compliance with these standards. ISO 13849-1:2006 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. It applies to SRP/CS, regardless of the type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kinds of machinery. It does not specify the safety functions or performance levels that are to be used in a particular case. ISO 13849-1:2006 provides specific requirements for SRP/CS using programmable electronic system(s). It does not give specific requirements for the design of products which are parts of SRP/CS. Nevertheless, the principles given, such as categories or performance levels, can be used.
