SPECIFICATION FOR GENERAL REQUIREMENTS FOR NICKEL AND NICKEL
ALLOYS SEAMELSS PIPE AND TUBE

1.Scope 

1.1 This specification contains various reuiremens that, with the exception of Sections 5 and 10 are mandatory requiremants to the following ASTM nickel and nickel alloy, seamless pipe and tube specification.

1.2 One or more of the test requirements of Section 5 apply only if specifically stated in the product specification or in the purchase oder. 

1.3 In case of conflict between a requirement of the product specification and requirement of this general specification, 
only the requirement of te product specification need to be satisfied. 

1.4 The values ststed in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 

1.5 The following safety hazards caveat pertains only to the test method portion, Section 5, of this standard: This standard does not purport to address all of tne safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine tne applicability of regulatry limitations prior to use.
