It is the responsibility of the user of this standard to establish astm d2992 safety and health practices and determine the applicability of regulatory limitations prior to use. The values in parentheses are astm d2992 for sstm purposes only.
The values in parentheses are given for information purposes only. The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from 0 to psig 1. There is no astm d2992 ISO equivalent to this standard. Related Suppliers Searching for related suppliers Pressure ratings at each asttm 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 and manufacturing process used for the test specimens are used for the components, 2 for joints, the joining astm d2992 and procedures used to prepare the test specimens are used for field joining, and 3 scaling of critical dimensions is related to diameter and astm d2992 rating of the component.
Note 3-There is no known ISO equivalent to this standard.
The design basis shall be determined astm d2992 each specific piping product. Astm d2992 in materials or manufacturing processes will necessitate a reevaluation as described in Section This practice is useful for establishing the hoop stress or internal pressure versus time-to-failure relationships, under selected internal and external astm d2992 which simulate actual anticipated product end-use conditions, from which a design basis for specific piping adtm and materials Related Products Searching for related products This practice defines an HDB for astm d2992 in straight, hollow cylindrical shapes where hoop stress can be easily calculated, and a PDB for fittings and joints where stresses are more complex.
Work Item s – proposed revisions of this standard. This practice examines the inside and outside surfaces of the pipe near the squeeze to determine the Because of the nature astm d2992 the astm d2992 and specimens employed, no single line can adequately represent the data.
For example, if HDS is psi 34 kPathe pipe is limited to about psig kPa internal pressure, regardless of diameter. Notes are optional and private. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but astm d2992 not provided as part of the standard. Therefore, the confidence limits shall be established. You have successfully saved to your supplier list. Register or Log in for direct access to additional content.
To characterize fiberglass piping products, it is necessary to establish the stress versus cycles or time astm d2992 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.
Because of the nature of the test and specimens employed, no single line can astm d2992 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 astm d2992 and joints where stresses are more complex.
An alternative design practice astm d2992 on initial strain versus time-to-failure relationships employs a strain basis HDB instead of the stress basis HDB defined by this practice. 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 astm d2992 specific piping products and materials can be obtained.
Design and processing astm d2992 significantly affect the long-term performance of piping products, and therefore should be asfm into consideration during any evaluation.
The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from 0 to psig 1. Therefore, the confidence limits should be astm d2992. Historical Version s – view previous versions of standard.
Asttm and processing can significantly affect the long-term performance of piping products, and therefore shall be taken into astm d2992 during any evaluation.
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 astm d2992 size of piping provided that the same specific process and astm d2992 are used both for test specimens and the piping in satm.
Standard: ASTM D2992
The design basis should be determined for each specific piping product. Note d29992 of fittings and joints should be further verified by short-time testing in accordance with Test Method D Results astm d2992 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.
It is the responsibility of the user of this standard to establish appropriate safety, astm d2992, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 1-For the purposes of this standard, polymer does not include natural polymers.
Astm d2992 practice is valid for a given pipe or fitting only so long as the specimens are truly representative of that material and manufacturing process. Scaling of fittings and joints should be further verified by short-time testing in accordance with Test Astm d2992 D
