Preliminary PagesMaterials testing systems are potentially hazardous.Materials testing involves inherent hazards from highforces, rapid motions and stored energy. You must beaware of all moving and operating components whichare potentially hazardous, particularly the actuator in aservohydraulic testing system or the moving crossheadin an electromechanical testing system.Whenever you consider that safety is compromised,press the Emergency Stop button to stop the test and isolate the testing system from hydraulic or electricalpower.Carefully read all relevant manuals and observe allWarnings and Cautions. The term Warning is usedwhere a hazard may lead to injury or death. The termCaution is used where a hazard may lead to damage toequipment or to loss of data.Ensure that the test set-up and the actual test you willbe using on materials, assemblies or structures constitutes no hazard to yourself or others. Make full use ofall mechanical and electronic limits features. These aresupplied for your safety to enable you to prevent movement of the actuator piston or the moving crosshead beyond desired regions of operation.The following pages detail various general warningsthat you must heed at all times while using materialstesting equipment. You will find more specific warnings and cautions in the text whenever a potential hazard exists.Your best safety precautions are to gain a thorough understanding of the equipment by reading your instruction manuals and to always use good judgement.v

Preliminary PagesM10-94400-1WarningDisconnect the electrical power supply before removing the covers to electrical equipment.Disconnect the equipment from the electrical power supply before removing any electrical safety covers or replacing fuses. Do not reconnect the power source whilethe covers are removed. Refit covers as soon as possible.Disconnect power supplies before removing the covers to rotating machinery.Disconnect the equipment from all power supplies before removing any cover which gives access to rotatingmachinery. Do not reconnect any power supply whilethe covers are removed unless you are specifically instructed to do so in the manual. If the equipment needsto be operated to perform maintenance tasks with thecovers removed, ensure that all loose clothing, long hair,etc. is tied back. Refit covers as soon as possible.Shut down the hydraulic power supply anddischarge hydraulic pressure before disconnecting any hydraulic fluid coupling.Do not disconnect any hydraulic coupling without firstshutting down the hydraulic power supply and discharging stored pressure to zero. Tie down or otherwise secure all pressurized hoses to prevent movement duringsystem operation and to prevent the hose from whippingabout in the event of a rupture.vi

Preliminary PagesWarningShut off the supply of compressed gas anddischarge residual gas pressure before disconnecting any compressed gas couplingDo not release gas connections without first disconnecting the gas supply and discharging any residual pressureto zero.Use protective shields or screens if any possibility exists of a hazard from the failure ofa specimen, assembly or structure undertest.Use protective shields whenever a risk of injury to operators and observers exists from the failure of a test specimen, assembly or structure, particularly where explosivedisintegration may occur. Due to the wide range of specimen materials, assemblies or structures that may be tested,any hazard resulting from the failure of a test specimen, assembly or structure is entirely the responsibility of theowner and the user of the equipment.Protect electrical cables from damage andinadvertent disconnection.The sudden loss of controlling and feedback signalswhich can result from a disconnected or damaged cablecauses an open loop condition which may drive the actuator or crosshead rapidly to its extremes of motion.Protect all electrical cables, particularly transducer cables, from damage. Never route cables across the floorwithout protection, nor suspend cables overhead underexcessive strain. Use padding to avoid chafing where cables are routed around corners or through wall openings.vii

Preliminary PagesM10-94400-1WarningWear protective clothing when handlingequipment at extremes of temperature.Materials testing is often carried out at non-ambient temperatures using ovens, furnaces or cryogenic chambers.Extreme temperature means an operating temperature exceeding 60 C (140 F) or below 0 C (32 F). You mustuse protective clothing, such as gloves, when handlingequipment at these temperatures. Display a warning notice concerning low or high temperature operation whenever temperature control equipment is in use. Youshould note that the hazard from extreme temperaturecan extend beyond the immediate area of the test.Take care when installing or removing aspecimen, assembly or structure.Installation or removal of a specimen, assembly or structure involves working inside the hazard area between thegrips or fixtures. Keep clear of the jaws of a grip or fixture at all times. Keep clear of the hazard area betweenthe grips or fixtures during actuator or crosshead movement. Ensure that all actuator or crosshead movementsnecessary for installation or removal are slow and,where possible, at a low force setting.viii

Preliminary PagesWarningDo not place a testing system offline fromcomputer control without first ensuring thatno actuator or crosshead movement will occur upon transfer to manual control.The actuator or crosshead will immediately respond tomanual control settings when the system is placed offline from computer control. Before transferring to manual control, make sure that the control settings are suchthat unexpected actuator or crosshead movement cannotoccur.Keep clear of the operating envelope of arobotic device unless the device is de-activated.The robot in an automated testing system presents a hazard because its movements are hard to predict. The robotcan go instantly from a waiting state to high speed operation in several axes of motion. During system operation ,keep away from the operating envelope of the robot. Deactivate the robot before entering the envelope for anypurpose, such as reloading the specimen magazine.ix
