This document (EN 3155-001:2016) has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2017, and conflicting national standards shall be withdrawn at the latest by March 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 3155-001:2009. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
This European Standard specifies:  the electrical, mechanical, environmental and dimensional characteristics of electrical contacts used in elements of connection, including coaxial, triaxial and quadrax contacts;  the conditions for qualification, acceptance testing and quality assurance;  the test programs and groups. It is applicable to removable crimp contacts, wrap contacts, solder contacts used in connectors or in other elements of electrical connection. In case of conflict or missing information between the EN 3155-001 and the product standards, the product standard shall govern. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

This standard covers male and female contacts of all types and technologies: cylindrical or rectangular entry contacts, flat contacts of the blade type, etc., stamped, formed or machined contacts. Stamped and formed technology for body contact are not allowed.
5.1.2 Mating end of female contact, cylindrical contacts Unless otherwise stated in the product standard, the mating end of female contacts from size 08 to 24, shall be of the restricted entry type and shall not permit the introduction of a gauge which has a diameter 0,13 mm greater than the maximum diameter of the male contact. 5.1.3 Mating end of male contacts, cylindrical contacts Unless otherwise stated in the product standard, the mating end of the male contacts shall be approximately spherical. A flat is permitted at the end; its dimensions are given in Table 1. Table 1 — Gauge dimensions for male contact Contact size Pin active area contact diameter
