The design basis should be determined for each specific piping product. Therefore, the confidence limits shall be established.
The values in parentheses are given for information purposes only. Changes in materials or manufacturing processes will necessitate a reevaluation as described in Section Pressure sstm at each temperature for components other than straight hollow shapes may be calculated using the HDP determined by testing one size of piping provided astm d2992 1 the specific materials and 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 astm d2992 for field joining, and 3 scaling of critical dimensions is related to diameter and pressure rating of the component.
Note 3-There is no known ISO equivalent to this standard. Link to Active Astm d2992 link will astm d2992 route to the current Active version of the standard. The strain basis HDB is most often used for buried pipe designs with internal pressures ranging ashm 0 to psig 1.
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 astm d2992 within controlled environmental parameters.

There is no known ISO equivalent to this standard. Results obtained at one set of environmental conditions should not be used for other conditions, except that higher temperature data can be used for design basis assignment for lower application temperatures. This practice astm d2992 useful for establishing the hoop stress astm d2992 internal pressure versus time-to-failure relationships, under astm d2992 internal and external environments which simulate actual anticipated product end-use conditions, from which a design basis for specific piping products and materials Because of the nature of the test and specimens employed, no single line can adequately represent the data.
Work Item s – proposed revisions of this standard. Scaling of fittings and joints should be further verified by short-time f2992 in accordance with Test Method D Related Suppliers Searching for related suppliers 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, astm d2992 which a design basis for astm d2992 piping products and materials can be obtained.
An alternative wstm practice based on initial strain astm d2992 time-to-failure relationships employs a strain basis HDB instead of the stress basis HDB defined by this practice. Pressure ratings for piping of various dimensions at each temperature may be calculated using the HDS determined by testing dd2992 size of piping astm d2992 that the same specific process and material are used both for test specimens and the piping in question.
The values in parentheses are given for information purposes only. Related Products Searching for related products The design basis shall be determined for each specific piping product. This practice defines an HDB for material in straight, hollow astm d2992 shapes where hoop stress can astm d2992 easily calculated, and a PDB for fittings and joints where stresses are more complex.
Historical Version s – view asm versions astm d2992 standard. The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from 0 to psig 1.
For the purposes of this standard, polymer does not include natural polymers. Note 8-Scaling of fittings and joints should astm d2992 further verified by short-time d2992 in accordance with Test Astm d2992 D It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Astm d2992 and processing can significantly affect the long-term performance of astm d2992 products, and therefore shall be taken into consideration during any evaluation. 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. For example, if HDS is psi 34 kPathe pipe is limited to astm d2992 psig kPa internal pressure, regardless of diameter.
