This practice is useful for establishing the hoop stress or internal pressure versus time-to-failure relationships, under selected internal and external environments which simulate actual anticipated product end-use conditions, from which a design basis for specific astm d2992 products and materials You have successfully saved to your supplier list.

Design and astm d2992 can significantly affect the long-term performance of piping products, and therefore shall be taken into consideration during any evaluation. Note 1-For the purposes of this standard, polymer does not include natural polymers.

Pressure ratings for piping of various dimensions at each temperature may be calculated using the HDS determined by testing one size of piping provided that the astm d2992 specific process and material are used both for test specimens and astm d2992 piping in question.

This practice defines an HDB for material in straight, hollow cylindrical shapes where hoop stress can be easily astm d2992, and a PDB for fittings and joints where stresses are more complex.

Pressure ratings at each astm d2992 for components other than straight hollow shapes may be calculated using the HDP determined by testing one size of piping provided that 1 the specific materials d2992 manufacturing process used for the test specimens are used for the components, 2 for joints, the joining materials and procedures used to prepare the test specimens are used for field joining, and 3 scaling of critical dimensions is astm d2992 to diameter and pressure astm d2992 of the component.

The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from 0 to psig astm d2992. Because of the nature of the test and specimens employed, no single line can adequately represent the data.

This practice defines an HDB for material in straight, hollow cylindrical shapes where hoop stress can be easily calculated, and a PDB for fittings and joints where stresses are more complex. Therefore, the confidence limits shall be established. For the purposes of this standard, polymer does not include natural polymers. Link to Active This link will always astm d2992 to the current Active version of the standard. Note 3-There is no known ISO equivalent to this astm d2992. There is no known ISO equivalent astk this standard.

Work Item s adtm proposed revisions of this standard. An alternative design practice based on initial strain versus time-to-failure relationships employs a strain basis HDB instead of the stress basis HDB defined by this practice. Therefore, the confidence astm d2992 should be established. Results obtained at one set of environmental conditions should not be used for other conditions, except that higher temperature 2d992 can astm d2992 used for design basis assignment for astm d2992 application temperatures.

The design basis should be determined for each specific piping product.

This practice is useful for establishing the hoop stress or internal pressure versus time-to-failure relationships, under selected internal and external environments which simulate actual anticipated product end-use conditions, from which a astm d2992 basis for specific piping products and materials can be obtained.

The strain basis HDB is most often used for buried pipe designs with internal astm d2992 ranging from 0 to psig 1. This practice is valid for a given pipe or fitting only so long as the specimens are truly representative of that material and manufacturing process.

To characterize fiberglass piping products, it is necessary to establish the stress versus cycles or time to failure, or pressure versus cycles or time to failure relationships over three or more logarithmic decades of time cycles or hours within controlled environmental parameters. The design basis shall be determined for each specific piping product.
