SIST EN 547-3:1998+A1:2008

SIST EN 547-3:1998+A1:2008 is the Slovenian adoption of the CEN European Standard EN 547-3:1996+A1:2008. It gives anthropometric data for machinery design, especially for calculating access opening dimensions with EN 547-1 and EN 547-2. Engineers and safety specialists use it when they need body-size values for whole-body access or access for parts of the body.

What does SIST EN 547-3:1998+A1:2008 specify?

SIST EN 547-3:1998+A1:2008 specifies current human body measurements needed to calculate access opening dimensions for machinery. The data come from static measurements of nude persons and are intended for use with EN 547-1 and EN 547-2.

The standard organizes the subject into three main clauses and two informative annexes. Clause 3 states the general requirement to use the data with the access-opening principles in EN 547-1 and EN 547-2, while Clause 4 gives the anthropometric data and the measurement descriptions.

The scope is limited to survey-based European anthropometric values. The data take neither body movement nor clothing, equipment, machine operating conditions or environmental conditions into account.

What are the key requirements of SIST EN 547-3:1998+A1:2008?

SIST EN 547-3:1998+A1:2008 sets the body-size data that designers substitute into the calculation methods in EN 547-1 and EN 547-2. In practice, the document tells you which human dimensions to use, which population percentiles to consider, and how the listed values were derived.

Using the data for machinery access

Clause 3 says anthropometric measurements are the basis for minimum access-opening dimensions. If machinery needs access openings, the designer is expected to apply EN 547-1 for whole-body access and EN 547-2 for access to parts of the body. That matters because the standard is not a standalone sizing rule - it is a data source for those two companion parts.

Population basis and percentiles

Clause 4 states that the values are based on European survey information representative of population groups totaling at least three million people. Both men and women are included, and the data are given for the 5th, 95th and 99th percentiles where relevant. In practice, this helps designers cover smaller and larger users rather than designing for an average body size.

How the European values are formed

Clause 4.1 explains two ways the European values are built from national surveys: either from pooled female and male populations or from separate female and male percentiles. For separate percentiles, the standard uses the mean of the female and male values, then selects the lower result for the 5th percentile and the higher result for the 95th and 99th percentiles. This gives a practical European value for design work.

What the tables provide

Table 1 lists the anthropometric values used in calculations, such as body height, body depth, grip reach, hand breadth and foot length. Table 2 explains the notations and shows whether a measurement is a fixed value or derived from another body measurement. That helps a designer understand what each symbol means before using it in EN 547-1 or EN 547-2.

Relationship to Machinery Directive use

Annex ZA and Annex ZB link the standard to EU machinery directives and state that compliance with the normative clauses can give a presumption of conformity within the scope of the standard. For users, this is the part that connects the ergonomic data to regulatory use on machinery designs.

What terms does SIST EN 547-3:1998+A1:2008 define?

• Anthropometric data - Human body measurement values used here to size machinery access openings.
• Percentile - A population position used to pick design values for smaller or larger people, such as the 5th, 95th and 99th percentiles.
• Grip reach (forward reach) - A forward reach measurement used in the table of body dimensions.
• Operating arm length - A derived reach measure obtained from grip reach minus a fixed value.
• Forearm reach - A derived arm-length measure used in the table of notations.
• prEN 979 - The referenced basic list of human body measurement definitions for technical design.

Who uses SIST EN 547-3:1998+A1:2008?

SIST EN 547-3:1998+A1:2008 is used by machinery designers, ergonomics specialists, and safety engineers who need body-size data for access openings. It is also relevant to quality and compliance teams checking whether a machine design follows the EN 547 access-opening approach. Buyers and integrators can use it to understand whether a machine design is based on European anthropometric values rather than ad hoc dimensions.

What changed in SIST EN 547-3:1998+A1:2008 from the previous edition?

SIST EN 547-3:1998+A1:2008 supersedes EN 547-3:1996 and includes Amendment 1 approved by CEN on 2008-08-14. The foreword says that the text introduced or altered by the amendment is marked in the document.

Which standards are used with SIST EN 547-3:1998+A1:2008?

• EN 547-1 - Gives the principles for determining dimensions required for openings for whole body access into machinery.
• EN 547-2 - Gives the principles for determining dimensions required for access openings.
• prEN 979 - Supplies basic definitions of human body measurements used in the measurement descriptions.
• EN 614-1 - Gives ergonomic design principles and general terminology for machinery design.

What does the SIST EN 547-3:1998+A1:2008 document contain?

SIST EN 547-3:1998+A1:2008 contains a scope, normative references, general requirements, and a data clause with two parts. Clause 4 includes Table 1 with anthropometric survey values and Table 2 with notations and measurement descriptions. The annexes add the relationship to EU machinery directives, which is useful for conformity work and regulatory mapping.
