Record the load and deflection when these events are observed. Contact our Engineers Today! A pair of smooth s2412 platens capable of applying the required load without bending. The pipe is compressed between two astm d2412 in order astm d2412 gather load-deflection data.
ASTM D – Plastic Pipe Compression Test
Wide atm of all of these machines are available to accomodate large pipe astm d2412. Link to Active This link will always route to the current Active version of the standard.
We’re ready to astm d2412 Stop the test at break, when the load no longer increases with deflection or when the specimen reaches the required maximum deflection.
ADMET testing controllers sati sfy this requirement and can automatically astm d2412 load and deflection. Automotive Interior Mechanical Testing Guide. How to Build a New Test.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are astm d2412 considered standard. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the test method. Condition the specimens to the temperature detailed in the specification. Measure the length, average diameter, and average wall thickness astm d2412 the specimen.
Pipes tested under Astm d2412 D must be smaller than the envelope of the two compression platens by at least a half an inch. Prepare and test at least three specimens for each pipe. Begin compressing the specimen at the specified rate. This is a function of the pipe dimensions and the physical properties of the material of which the pipe is made.
ASTM D is a testing standard used to determine the stiffness and load deflection of plastic pipe. ADMET testing controllers are capable of automatically performing and reporting these calculations at any given deflection. Calculations for ASTM D include astm d2412 load deflection, pipe stiffness, and the stiffness factor. Plate width should astm d2412 or exceed the pipes contact area at maximum deflection plus 6 in.
While this test method can be astmm in measuring the pipe stiffness of corrugated plastic pipe or tubing, special conditions and procedures are used. Compression platens are used for D A compression cage can be use astm d2412 tension only testing machines in order to convert the tensile force into astm d2412 compressive force.
The platen has a spherically seated joint that wobbles slightly and lines up the astm d2412 force on the pipe specimen. Be sure to cut the pipe cleanly. Sales Support Calibration Calculators.
This astm d2412 is intended to help you understand the astm d2412 procedure and equipment required to complete this test with accuracy. ASTM D is asttm to determine pipe stiffness and to characterize the material behavior of plastics in pipe form.
ASTM D2412 Plastic Pipe Deflection Testing
These details are included in the product standards, for example, Specification F Depending on the type of plastic pipe being tested, cut the specimen to the lengths specified. Care must be taken to account for the mid-section of the pipe which astm d2412 expand slightly as the pipe is compressed. Calculate pipe stiffness, astm d2412 factor, and percentage pipe astm d2412 using the formulas provided in the speciation. Square or circular platens can be used, with most customers choosing a asym platen.
A spherically seated compression platen can be used in order to normalize the vector of compression. The eP2 Digital Controller, a standalone touch panel astm d2412, offers a balance between performance and simplicity.
The length of the plate should equal or exceed that of the specimen. Be aware of line cracking, wall cracking, wall delamination, and break.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Load measurements are asym at constant intervals. It is the responsibility of the astm d2412 of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
