Application Specific Accessories
Bend tests provide a quick and simple way to determine the strength and deformation properties of wood and timber products. A range of fixtures are available to cater for various specimen sizes and strengths. All fixtures can be equipped with optional support rollers, some of which feature articulation to cater to warped specimens. These fixtures are ideal for tests on MDF and fiberboard, as well as natural timber.
Principle of Operation 2820-04x Series bend fixtures are designed for static bend/flexure testing on a range of wood and timber products according to common international standards. The beam attaches to the test instrument using simple mechanical interfaces that allow it to be removed when not in use. A range of optional support anvils and four-point conversion kits allow the fixtures to be configured to meet a wide range of standards. Specimens of the required size are supported by two anvils attached to a base beam. Force is applied either at the center (three-point bend) or at two points between the supporting rollers (four-point bend).
Application Range • Static bending tests on a wide range of wood and timber specimens, including MDF and fiberboard at ambient temperatures • Meets the following standards when used with appropriate optional anvil sets/4-point conversion kits and/or deflectometry: JIS A 5905, JIS A 5906, JIS A 5908, JAS 112, JAS 601, BS 373, BS 5669, EN 310, EN 789, ISO 3133, ASTM D1037, ASTM D3037, and ASTM D143
