ASMIE material specifications arc those that are published in the HPVC Section II. Parts A. B and C. The majority of ASMIE material specifications are based on ASTM or AWS specifications.
ASME ferrous material specifications are identitied by the letters “SA” as the first chanicters in the specification number. For example. SA-l06 refers to an ASME specitication. whereas A 106 refers to an ASTM specification. ASME nonferrous material specifications ate identified by the letters “SB” as the first characters in the specification number For esample. 513-366 refers to tin ASMIE materi4tl specification. whereas, 11366 refers to an ASTM material specification. ASME svelding rod, filler metal, and electrode material specifications are identified by the letters “SFA” its the first characters in the specification number. For example. SFA-5. l/SFA.5. I M refers to an ASMF. specification, whereas, A5.l?A5.IM refers to an AWS welding material specification.
As ASME adopts ASTM and other acceptable international material specifications for pressure vessel construction, the requirements in the ASME specification generally will be the same as those in the adopted ASTM or the acceptable international s.pecitication. However, some of the ASME material specifications include a statement underneath the title of the specification that lists the exceptions from the ASTM br international) specification, or additional ASME requirements Users should consult the appropriate specification to determine the differences between the ASME and the ASTM.’AWS (or other intensational) specifications.
3.1 ASME Material Specifications
In general. matenals used for ASME BPVC construction are required to be ASME materials. The BPVC Section II. Pan I), Tables IA. Ill, 2A. 213, C, 5A and 511 list all materials that may be used for ASME Code construction, Materials that hase a temperature listed in the column titled “Applicability and Masinsum Temperature Limits” may he used for ASME (ode construction within the indicated temperature range for the applicable BPVC Section. Materials that Isase “NP” listed in this column may not be used 11w construction under that Section, Materials that are not listed in the BPVC Section II. Pan I). may be used for ASME Code construction if permitted by an ASME (‘ode Case.
The materials used for ASME Code construction must be furnished in accordance with the specifications listed in BPVC, Section II. The materials for Code use shall be ordered, produced, and documented in accordance with either the ASME specification in Section Il (except as limited by the rules of the applicable construction code), or with an ASTM specification listed in Table 11-200-I, or with a specification issued by other acceptable non-ASThI (international) specifications listed in Table 11-200-2, or in a ASMIE Code Case for the construction code(s) listed in the ASME Code Case.
The ASME SA material specifications include a statement under the titk of the specification that identifies the related ASTM or the international material specification. Many ASME SA material specifications arc identical with a particular edition of the same ASIM specification, in which case the ASME SA specification states that the ASME SA specification is identical with the ASTM or the international material specification, and lists the ycar date of the publication of that specification that is used for adoption of it as the ASME. SA material specification. However, INst all of the ASME SA material specifications are identical with the ASTM or the related intensational material specification. In such cases the statement under the title of the ASME SA specification also lists the exceptions. or modifications, or additional requirements to the adopted specification for use in ASME Code construction. For example, the ASNtE SA specification SA-335 adds hardness requirements for Grades P23 and P911 pipes. Another example is fusion welded pipes under specifications SA-671 and SA672 that include an additional statement that limit fabrication of such pipe for ASMIE Section III construction to Manufacturers holding the appropriate ASMF. Certificate of Authoritation and Certification Mark.
Also the ASME SB nonferrous material specifications include a statement under the title of the specification that identifies the related ASTM or the international material specification. Some of the ASME SB material specifications arc identical with a particular edition of the same ASTM specification, in which case the ASME SB specification states that the ASM SB specification is identical with the ASTM or the international material specification, and lists the date of publication of that specification that is used for adoption of it as the ASME material specification. 1—lowever, most of the ASME SB nonferrous material specifications are not identical with the ASTM or related international material specification because many do not include the mandatory requirement for a certification and test report. In such cases the statement under the title of the ASME SB specification also lists the exceptions, modifications, or additional requirements, and includes the statement that certification and test reports have been made mandatory for the adopted specification for use in ASME Code construction.
3.2 ASTM Material Specifications
In general, materials used for ASME 1331 Pressure Piping Code designs must be ASTM materials. The B3 I Pressure riping Codes contains table listings of ASTM materials that are for use within the scope of that Code. Each ASME Code also includes rules for the usc of unlisted materials, whether such materials are ASTM. ASME, or produced to another material specification.
For BPVC applications, BPVC Section II, Part A, Table 11-200-I and Section II, Part B. Table 11-200- I list the dates of the latest adopted ASTM material specifications and other acceptable ASTM specification editions that may be used in lieu of the corresponding ASME specifications, provided the additional requirements referenced in the subtitle are met. Likewise. Tables 11-200-2 in Section II, Part A and in Part B list the latest and other acceptable editions of non-ASTM specifications that may be used in lieu of the corresponding ASME speciuications. provided the additional requirements listed in the ASMI! specifications arc met.
ASTM specifications may be used if listed in BPVC Section II. Part A.. Table 11-200-1, except as limited by rules in the applicable construction code. If the BPVC Data Report is registered with National Board, material specifications must be in accordance with ASME SA specifications.
3.3 Dual Marked Materials
Occasionally, users may come across items that are marked as both ASME and ASTM materials. For example, a pipe may be marked as “A/SA- 106” or SA- I 06/A- 106”. which indicates that the material complies with the requirements of both the ASTM specification and the corresponding ASME specification. Materials marked in this fashion may be used in applications requiring either ASME or ASTM materials.ASME PTB-8 pdf free download.
