B11 Standards, Inc. is ANSI-accredited Standards Developing Organization that administers and develops the ANSI B11 series of American National Standards and Technical Report on machine/machine too/machinery safety. Founded in 2010, B11 Standards Inc. is also accredited by ANSI as the United States Technical Advisory Group Administrator to ISO Technical Committee 199 (machinery safety standards) and ISO Technical Committee 39 Subcommittee 10 (machine tool safety standards).
B11 Standards Inc. also participates in a very large number of both national and international standards development activities.
Standardization / standards provide a bridge between research, innovation and the market, thereby strengthening competitiveness and boosting growth and jobs. Standards are a valuable tool for market dissemination of research and development results and can therefore contribute to the objectives of overall market innovation and competitiveness.
The project on Safety Standard for Power Presses, B11, was initiated under the procedures of the American Engineering Standards Committee (which became the American Standards Association, the United States of America Standards Institute, and in 1969 the American National Standards Institute - ANSI), with the National Safety Council as sponsor. The first standard, bearing the title Safety Code for Power Presses and Foot and Hand Presses, was developed by Sectional Committee B11 and was approved on November 13, 1922. Only two purposes of that "code" were listed. The first and primary use was for state industrial commissions in developing their workplace codes. The second use was as an operating guide for users operating press production systems.
Revisions of the first B11 standard were issued in 1926, 1937, 1948, 1960, 1971, 1982, 1988, and 2001. The Association For Manufacturing Technology (AMT) assumed this activity from the National Safety Council in 1970 and administered the activity until 2010, when they transferred it to B11 Standards. Inc., which is now the ANSI-Accredited Standards Developing Organization (SDO) for the B11 series of safety standards for machines and is the Secretariat for the B11 Accredited Standards Committee (ASC).
B11 Standards, Inc. is also accredited by ANSI as the United States Technical Advisory Group (TAG) Administrator to two International Standards Organization (ISO) Technical Committees (TC), ISO/TC 199 on Machinery Safety and ISO/TC 39 /SC 10 on Machine Tool Safety.
The B11 ASC is comprised of organizations representing different stakeholder groups having a substantial interest and competence in the overall scope of B11 standards. It is recognized by ANSI as the body that evaluates and votes on final draft standards (or technical reports) developed by B11 writing subcommittees for approval as American National Standards and ANSI Technical Reports by the ANSI Board of Standards Review. Each of the standards and tecnical reports within the B11 series has its own writing subcommittee. These subcommittees function somewhat autonomously from The B11 ASC, with their own Chair (and possibly Vice-Chair), however, they are ultimately responsible and answerable to the B11 ASC. Once they complete work on their document, it is turned over to the Secretariat for procedural commenting and balloting by the public and the interested Voting Group of B11 ASC Member organizations, which forms the "consensus body." Once this process has been completed, the candidate standard is submitted to the ANSI Board of Standards Review for approval as a new or revised or reaffirmed American National Standard.
While the U.S. TAGs to both ISO/TC 199 and ISO/TC 39 /SC10 operate under the ANSI Model Procedures, the B11 ASC uses its own standards development procedures, which conform to or exceed the ANSI Essential Requirements and are subject to periodic review and approval by the ANSI Executive Standards Council.

Organization and Application of B11 Documents
The B11 standards and technical reports can be associated with the ISO A-B-C level structure as described and as shown in the figure below.
This standard is the basis for a set of standards which have the following structure:
• Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that can be applied to machinery;
• Type-B standards (generic safety standards) deal with one or more safety aspects or one or more types of safeguards that can be used across a wide range of machinery:
• Type-B1 standards are on particular safety aspects (e.g., safety distances, surface temperature, noise);
• Type-B2 standards are on safeguards (e.g., two-hand controls, interlocking devices, pressure sensitive devices, guards);
• Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines.
The ANSI B11.0 (Safety of Machinery â€“ General Requirements and Risk Assessment) is an type-A standard that applies to a broad array of machines. ANSI B11.19, ANSI B11.20 and all the ANSI B11 Technical Reports are all type-B documents addressing safety elements that can be used across a wide range of machinery.
The machine-specific (type-C) B11 standards contain detailed safety requirements for a particular machine or group of machines (see the list of machine-specific standards). The ANSI B11.0, ANSI B11.19 and the machine-specific B11 standards are intended to be used concurrently by the supplier and user of machines. When a type-C standard deviates from one or more provisions dealt with by this standard or by a type-B standard, the type-C standard takes precedence.
ANSI B11.0 is primarily written for machines that fall within the scope of the machine-specific B11 series of standards. However, ANSI B11.0 may also be applied to machines based on the reader's definition or application within the context of the risk assessment, for example:
• machines that do not fall within the scope of a machine-specific B11 standard;
• machines that are specifically excluded from a machine-specific B11 standard; or
• machines that fall within the scope of another machine-specific standard.
