b'F LexuraLF ixturesFlexural test fixtures are a relatively simple solution for determining the strength and deformation properties of materials such as wood and timber products.Starrett can offer a variety of test fixtures and accessories for performing 3- and 4-point bend testing.o PerationA beam attaches to the force testing frame, typically using a clevis adapter.In 3-point ixtures lexuralbending tests, two anvils are arranged along the beam with the sample under test residing on top of the two anvils.Force is applied in a compression direction mid-way between the two anvils for a 3-point test. F F Instead of a single anvil pressing the mid-section of the sample, two anvils may be used to press down on the sample for a 4-point test.t estinGs tandardsThe following testing standards can be met using standard Starrett flexural testing fixtures: ASTM D143 ASTM D1037 ASTM D3037 ISO 3133Additional testing standards are supported.Contact your Starrett representative for more information.b end3ALUMINUM For general-purpose 3-point bend testing applications Active Span Length is 4-150mm Replaceable Top and Bottom Radii for 4- and 5-point applications Aluminum bar with anodized finish, Hardened Steel radii Operating Temperatures 32 to 158F (0 to 70C)Bending FixturesLoad Capacity Upper Radius Lower Radius Weight (each) Clevis TypeModel No. N KGF LBF in mm in mm lbs kgs mm SupplyBEND-3-UR1-LR1 2,500 250 550 0.04 1.0 0.06 / 0.1 1.5 / 2.5 4.5 2.0 15.9 1BEND-3-UR1-LR2 2,500 250 550 0.04 1.0 0.08 / 0.2 2.0 / 5.0 4.5 2.0 15.9 1BEND-3-UR1-LR3 2,500 250 550 0.04 1.0 0.13 / 0.2 3.2 / 5.0 4.5 2.0 15.9 1BEND-3-UR15-LR1 2,500 250 550 0.06 1.5 0.06 / 0.1 1.5 / 2.5 4.5 2.0 15.9 1BEND-3-UR15-LR2 2,500 250 550 0.06 1.5 0.08 / 0.2 2.0 / 5.0 4.5 2.0 15.9 1BEND-3-UR15-LR3 2,500 250 550 0.06 1.5 0.13 / 0.2 3.2 / 5.0 4.5 2.0 15.9 1BEND-3-UR2-LR1 2,500 250 550 0.08 2.0 0.06 / 0.1 1.5 / 2.5 4.5 2.0 15.9 1BEND-3-UR2-LR2 2,500 250 550 0.08 2.0 0.08 / 0.2 2.0 / 5.0 4.5 2.0 15.9 1BEND-3-UR2-LR3 2,500 250 550 0.08 2.0 0.13 / 0.2 3.2 / 5.0 4.5 2.0 15.9 1BEND-3-UR3-LR1 2,500 250 550 0.12 3.0 0.06 / 0.1 1.5 / 2.5 4.5 2.0 15.9 1BEND-3-UR3-LR2 2,500 250 550 0.12 3.0 0.08 / 0.2 2.0 / 5.0 4.5 2.0 15.9 1BEND-3-UR3-LR3 2,500 250 550 0.12 3.0 0.13 / 0.2 3.2 / 5.0 4.5 2.0 15.9 1BEND-3-UR5-LR1 2,500 250 550 0.2 5.0 0.06 / 0.1 1.5 / 2.5 4.5 2.0 15.9 1BEND-3-UR5-LR2 2,500 250 550 0.2 5.0 0.08 / 0.2 2.0 / 5.0 4.5 2.0 15.9 1BEND-3-UR5-LR3 2,500 250 550 0.2 5.0 0.13 / 0.2 3.2 / 5.0 4.5 2.0 15.9 1116'
