Historical Version s – view previous astm d2412 of standard. ADMET testing controllers sati sfy this requirement and can automatically record load and deflection. Wide versions of all of these machines are available astm d2412 accomodate large pipe diameters. Calculations for ASTM D include percentage load deflection, pipe stiffness, and the stiffness factor.

The length of the plate should equal astm d2412 exceed that of the specimen. How to D2142 a New Test.

ASTM D2412 Plastic Pipe Deflection Testing

Astm d2412 ready to help! Square or circular platens astm d2412 be used, with most customers choosing a square platen. Be aware of line cracking, wall cracking, wall delamination, and break.

ASTM D is a testing standard used to determine the stiffness and load deflection of plastic pipe.

This summary is intended to help you understand the astm d2412 procedure and equipment required to complete astm d2412 test with accuracy. Be sure to cut the pipe cleanly. Measure the length, average diameter, and average wall thickness of the specimen.

ASTM D Plastic Pipe Deflection Testing – ADMET

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not astm d2412 standard. ADMET testing controllers astm d2412 capable of automatically performing and reporting these calculations at any given deflection.

Plate width should equal or exceed the astm d2412 contact area at maximum deflection plus 6 in. Record the load and deflection when these events are observed. The eP2 Digital Controller, a standalone touch panel unit, offers a balance between performance and simplicity. ASTM D is used to determine pipe stiffness and to characterize the material behavior of plastics in pipe form.

Load measurements ast, taken at constant intervals. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These notes and footnotes excluding those in tables astm d2412 figures shall not be considered as requirements of the test astm d2412.

It is the responsibility of d241 user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Pipes tested under ASTM D must be smaller than the envelope of the two compression platens by at astm d2412 a half an inch.

Depending on the type of plastic astm d2412 being tested, cut the specimen to the lengths specified. Sales Support Calibration Calculators. Condition the specimens to the temperature detailed in the specification.

A pair of smooth compression platens capable of applying the asgm load without bending. A spherically seated compression platen can be used in order to normalize the vector of compression. Compression platens are used for D While this test method can be 2d412 in measuring the pipe stiffness of corrugated plastic pipe or tubing, special conditions and procedures are used.

These details are included in the product standards, for example, Specification F Contact our Engineers Today! This is a astm d2412 of the pipe dimensions and the physical properties of the material of which the pipe is made.

The pipe is compressed between two platens in astm d2412 to gather astm d2412 data. The platen astm d2412 a spherically seated joint that wobbles slightly and lines up the load force on the pipe specimen. Prepare and test at least three specimens for each pipe. Begin compressing the specimen at the specified rate.

Calculate pipe stiffness, stiffness factor, astm d2412 percentage pipe deflection using astm d2412 formulas provided in the speciation.

Stop the test at break, when the load no longer increases with deflection or when the specimen reaches the required maximum deflection. A compression cage can be use for tension only testing machines in order to convert the tensile force into a compressive force. Automotive Interior Mechanical Testing Guide.
