Information on the most widely used ASTM standards within the materials testing industry
Model: WDW-50Y
UnitedTest offer a number of testing machine and test fixture to determine wood, timber mechanical strength parallel or perpendicular to the grain, cleavage strengths, Internal bond strengths and specific requirements like nail or screw withdrawal strength, flexure, compression test etc., Other standards UnitedTest wood testing fixtures conform to include ASTM D1037, ASTM D1761, BS373, BS5669, JIS A5905, JIS A5906 and JIS A5908.
Wood is commonly employed as an engineering material in the construction and furniture industry. With its broad range of physical and mechanical properties, wood from different species of trees can be chosen to suit specific application requirements. Standards, such as ASTM D143, cover testing methods to determine the mechanical properties including flexure strength, tensile strength and shear strength of wood. This allows engineers to compare the properties of various species before choosing one which best fits the engineering requirements.
General introduction

Wood is
commonly employed as an engineering material in the construction and
furniture industry. With its broad range of physical and mechanical
properties, wood from different species of trees can be chosen to suit
specific application requirements. Standards, such as ASTM D143, cover
testing methods to determine the mechanical properties including flexure
strength, tensile strength and shear strength of wood. This allows
engineers to compare the properties of various species before choosing
one which best fits the engineering requirements.
Chipboard, fiberboard, and particle board are engineered materials made by gluing wood chips or wood particles together with an adhesive under high pressure. Increased use of these materials has resulted in the need for more stringent testing to determine their strength properties.

Level authorization management function: to improve sftware and data security, can set different password to realize several class authorization management. Different user with different right to operate the machine, avoiding unexpected mistake because human error.
PC control system, with advantage of high integration, reliable performance, easy adjusment etc. can real time collect test data, on-time display test curve, test data file can be saved as ACCESS and SQL server, convenient for customer's data resource storage.
Automatically generate the testing report; the testing report can be displayed and printed, also it can be export in Excel/Access Format. Also, the user can edit the report format as requirement in report template;
Result recall function: after the test and saved, customer can open the test data and re-analysis at any time.
Results compare: observe several curve at same time, can fold curve or portion enlarge to analyze and compare sample characters.
Load~Time, Load~displacement, Displacement~time etc. curve smoothly switch, display test data, save, analysis and print.
