2 GENERAL
2.1 References
Standards and specifications adopted by reference are shown in Mandatory Appendix II. It is not considered practical to identify the edition of each referenced standard and specification in the text. Instead, the editions of the referenced standards and specifications are listed in Mandatory Appendix II.
2.2 Quality Systems
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
2.3 Relevant Units
This Standard states values both in metric units and U.S. Customary units. These systems of units are to be regarded separately. The US. Customary units are shown in parentheses or in separate tables. The values in these separate tables arc not exact equivalents; therefore, it is required that each system of units be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard.
2.4 Service Conditions
Criteria for selection of materials suitable for particular fluid service are not within the scope of this Standard.
2.5 Convention
For determining conformance with this Standard, the convention for fixing significant digits where limits and maximum and minimum values are specified shall be rounded as defined in ASTM E 29. This requires that an observed or calculated value shall be rounded tothe nearest unit in the last right-hand digit used forexpressing the limit. Decimal values and tolerance donot imply a particular method of measurement.
2.6 Denotation
2.6.1 Pressure Rating Designation.Class followedby a dimensionless number is the designation forpressure-temperature ratings.
2.6.2 Size. Nominal pipe size (NPS) followed by adimensionless number is the designation for nominalflange or flange fitting size. NPS is related to the refer-ence nominal diameter, DN, used in international stan-dards.The relationship is, typically, as follows.
