CSA Group Specifications for facially featured headforms

Preface This is the third edition of CSA Z262.6, Specifications for facially featured headforms. It supersedes the previous editions published in 2009 and 2002. In this edition an attempt was made to simplify the labeling of the anatomical points by naming them in accordance with anthropometric conventions versus generic lettering. The designations of the headforms were also changed to reflect the circumference of the four headform sizes (e.g., size 605 vs. 90th percentile). Finally, the 90th percentile headform (now size 605) was completely redesigned since it was found to be approximately 2% too large. Scope 1.1 This Standard specifies the dimensional and material requirements for facially featured headforms to be used in the testing of full-face protection and eye protection equipment, especially impact protection testing. 1.2 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
