Before You Contact MTS

Know your site number and system number

MTS can help you more efficiently if you have the following information available when you contact us for support.

The site number contains your company number and identifies your equipment type (material testing, simulation, and so forth). The number is usually written on a label on your MTS equipment before the system leaves MTS. If you do not have or do not know your MTS site number, contact your MTS sales engineer.

Example site number: 571167

When you have more than one MTS system, the system job number identifies which system you are calling about. You can find your job number in the papers sent to you when you ordered your system.

Example system number: US1.42460

Before You Begin

Safety first!

Other MTS manuals

Before you attempt to use your MTS product or system, read and understand the Safety manual and any other safety information provided with your system. Improper installation, operation, or maintenance of MTS equipment in your test facility can result in hazardous conditions that can cause severe personal injury or death and damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue. It is very important that you remain aware of hazards that apply to your system.

In addition to this manual, you may receive additional MTS manuals in paper or electronic form.

If you have purchased a test system, it may include an MTS System Documentation CD. This CD contains an electronic copy of the MTS manuals that pertain to your test system, including hydraulic and mechanical component manuals, assembly drawings and parts lists, and operation and preventive maintenance manuals. Controller and application software manuals are typically included on the software CD distribution disc(s).

Electronic manual conventions

The following paragraphs describe some of the conventions that are used in your MTS manuals.

As necessary, hazard notices may be embedded in this manual. These notices contain safety information that is specific to the task to be performed. Hazard notices immediately precede the step or procedure that may lead to an associated hazard. Read all hazard notices carefully and follow the directions that are given. Three different levels of hazard notices may appear in your manuals. Following are examples of all three levels.

Note For general safety information, see the safety information provided with your system.

DANGER

Danger notices indicate the presence of a hazard with a high level of risk which, if ignored, will result in death, severe personal injury, or substantial property damage.

WARNING

Warning notices indicate the presence of a hazard with a medium level of risk which, if ignored, can result in death, severe personal injury, or substantial property damage.

CAUTION

Caution notices indicate the presence of a hazard with a low level of risk which, if ignored, could cause moderate or minor personal injury, equipment damage, or endanger test integrity.

Notes provide additional information about operating your system or highlight easily overlooked items. For example:

Note Resources that are put back on the hardware lists show up at the end of the list.

The first occurrence of special terms is shown in italics.

Illustrations appear in this manual to clarify text. It is important for you to be aware that these illustrations are examples only and do not necessarily represent your actual system configuration, test application, or software.

Series 642 Bend Fixtures Product Information

Introduction

MTS Series 642 Bend Fixtures test the flexural bending properties of specimens. The grips are suited for fracture toughness tests (ASTM E-399), plastics tests (ASTM D-790, flex test), and composites tests (ASTM D-2344, short beam shear).

Note This manual covers the Model 642.001, 642.01A, 642.10B, and 642.25 Bend Fixtures, all of which have the same basic components. The illustrations on most of these pages show only the Model 642.10B, but the information provided applies to all four models. Where differences occur among the different models, these will be pointed out. Modelspecific illustrations are also included where appropriate.

What you need to know

MTS Systems Corporation assumes that you know how to use your controller. See the appropriate manual for information about performing any controllerrelated step in this manual’s procedures. You are expected to know how to perform the following procedure

•Turn hydraulic pressure on and off (for servohydraulic systems) or turn electrical power on and off (for electromechanical systems).

•Select a control mode.

•Manually adjust the actuator (servohydraulic) or crosshead (electromechanical) position.

•Monitor a sensor signal.

•Zero a sensor output.

•Install a specimen.

•Define a simple test.

•Run a test.

Series 642 Bend Fixture Functional Description

The bend fixtures have an upper and lower bedplate that attach to your load unit’s force transducer and actuator with cap screws. The Model 642.001, 642.01 and 642.10 bend fixtures attach directly to the actuator and force transducer, while the Model 642.25 Bend Fixture uses an adapter plate to attach to the actuator and force transducer.

Adjustable roller block assemblies slide back and forth in the bedplates, giving you different loading spans. The bedplates have scales, in metric and US units, for accurately adjusting the loading spans.

Series 642 Bend Fixtures Product Information

Introduction

The 642.01, 642.10, and 642.25 can be configured for three-point or four-point loading. Four-point loading uses two roller block assemblies in the upper bedplate and two in the lower bedplate. Three-point loading uses two roller block assemblies in the lower bedplate and a three-point option kit attached to the load cell.

Different diameter rollers can be used with the same roller block assemblies. Standard roller diameters are 0.125, 0.250, 0.375, 0.500, 0.750, 1.0, 1.25, 1.5, 1.75, and 2.0 inch, as well as 5, 8, 10, 12, 20, 30, 40, and 50 millimeter (see the tables on pages 14–18 for individual model standard diameters). MTS can also build rollers with custom sizes. See your sales representative if you require rollers of non-standard size.
