Concerne deux embases femelles acceptant des jacks de 3,50 mm à 3,60 mm (0,138 à 0,142 in) et de 2,44 mm à 2,49 mm (0,096 à 0,098 in). (Ces cotes sont respectivement les valeurs minimales et maximales des deux calibres mâles figurant dans la publication.)
Road vehicles — Frontal fixed barrier collision test method
Specifies a test method which should ensure that results obtained from different test facilities are directly comparable. Includes definitions; describes the impact test facilities, the state of the vehicle, the velocity to be used. The instrumentation will be given in an other ISO publication.
Recommended Practices for Ultrasonic Inspection of Structural Welds
1. SCOPE
1.1 This publication provides instructions for the ultrasonic inspection of
butt joints in material over 6 mm (0.2 inch) thichness, and in tee and corner
joints where suitable testing procedures can be established. It also provides
an outline of minimum equipment requirements, methods of calibrating the
equipment, and technical information on ultrasonics.
1.2 The two…
Copper alloys — Determination of aluminium as alloying element — Volumetric method
This method is applicable to all types of copper alloys listed in ISO publications. This method determines aluminium by chelatometric titration at a pH value of about 6, following a sodium fluoride demasking procedure, and using a voltametric indication. ISO 3110 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
