Adhesives - Determination of torque strength of anaerobic adhesives on threaded fasteners (ISO 10964:1993)

IEC 60335-2-103:2006+A1:2010 Deals with the safety of electric drives for horizontally and vertically moving gates, doors and windows for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. It also covers the hazards associated with the movement of the driven part.
This publication is to be read in conjunction with
IEC 60335-1:2010.
This consolidated version consists of the second edition (2006)  
and its amendment 1 (2010). Therefore, no need to order amendment in
addition to this publication.

Klebstoffe - Bestimmung der Drehfestigkeit von anaeroben Klebstoffen auf Befestigungselementen mit Gewinde (ISO 10964:1993)

Das in dieser Internationalen Norm beschriebene Prüfverfahren wird verwendet, um die Sicherungswirkung und Gewindeverbindungen anaerober Klebstoffe in Gewindeverbindungen vergleichend zu erfassen. Dieses Verfahren kann auch für andere Klebstoffarten benutzt werden, sofern dafür geeignet sind.

Adhésifs - Détermination des couples fonctionnels sur des fixations filetées collées avec des adhésifs anaérobies (ISO 10964:1993)

La CEI 60335-2-103:2006+A1:2010 Traite de la sécurité des motorisations électriques de portails, portes et fenêtres, à ouverture horizontale  ou verticale, pour usages domestiques et analogues, dont la tension assignée n'est pas supérieure à 250 V pour les appareils monophasés et à 480 V pour les autres appareils.  Elle couvre également les risques liés au mouvement de la partie entraînée.
Cette publication doit être lue conjointement avec la
CEI 60335-1:2010.
Cette version consolidée comprend la deuxième édition (2006) et
son amendement 1 (2010). Il n'est donc pas nécessaire de commander
l'amendement avec cette publication.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 10964 was prepared by Technical Committee
ISOnC 61, Plastics, Sub-Committee SC 11, Products.

required to unscrew a bonded nut and bolt assembly,
including the initial torque required to break the bond,
