2 GENERAL
2.1 References
Standards and specifications adopted by elerence are shown in Mandaton Appendix II. It is not considered practical to identify the edition of each referenced Standard and specification in the text, Lnstead, the editions of the referenced standards and specifications are listed In Mandatory Appendix II.
2.2 QualIty Systems
Requirements relating to the product manulacturers quality system programs are described in Nonmandatory Appendix A.
2.3 Re4evant Units
This Standard tats values in both 51 (Metric) units and U.S. Customaiy units, These systems of units arc to be regarded separately as standard. Within the text. the US. Customary units are shown in parentheses or in separate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equivalents; therefore, it is required that eadi system of units be used independently of the other. Combining values from th Iwo systems constitutes nonconformance with the Standard.
2.4 Service Conditions
Criteria for selection of materials suitable for particw lar fluid service are not within the scope of this Standard.
6 MATERIALS
(a) These fittings are furnished in gray iron, malleable iron, ductile iron, or steel as indicated in the individual tables.
(b) The chemical and mechanical properties of cast material shall equal or exceed those properties listed in ASTM A126, as applicable. Steel castings, forgings, or machined bar properties shall correspond to the comparable ASTM casting material specifications. The fittings manufacturer shall be prepared to certify conformance based on test data.
7 DIMENSIONS AND TOLERANCES
(a) Dimensions in metric units are given in Tables I through 5 for various types of fittings. Corresponding U.S. Customary values are given in Tables 1-1 through 1-5 in Mandatory Appendix I.
(b) At no point in the component wall shall the metal thickness be less than 90% of the values listed in the tables.
(13) 8 THREADS
8.1 Thread Form
All threads shall be in accordance with ASME 81.20.1.
8.1.1 Countersinks and Chamfers. All internal taper pipe threads shall be countersunk or chamfered a distance of not less than one-half the pitch of the thread at an angle of approximately 45 deg with the axis of the thread. External taper pipe threads shall be chamfered at an angle between 30 deg and 45 deg with the axis.,
