ASTM B737-10(R2021) pdf download.Standard Specification for Hot-Rolled and/or Cold-Finished Hafnium Rod and Wire
1.4 Unless a single unit is used, for example, corrosion mass gain in mg/dm 2 , the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use.
1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3.1.1 rounds, flats, tubes, andwrought powdermetallurgical products (single definition, common to nuclear and non- nuclear standards), n—a lot shall consist of a material of the same size, shape, condition, and finish produced from the same ingot or powder blend by the same reduction schedule and the same heat treatment parameters. Unless otherwise agreed between manufacturer and purchaser, a lot shall be limited to the product of an 8 h period for final continuous anneal, or to a single furnace load for final batch anneal.
5.1 Material covered by this specification shall be made by conventional hot and cold working procedures, from ingots produced by vacuum melting in electron beam or consumable arc furnaces, or both, ofa type conventionally used for reactive metals.
14.2 If any sample or specimen exhibits obvious contamination, improper preparation, or flaws disqualifying it as a representative sample, it shall be discarded and a new sample or specimen substituted.
14.3 Ifthe results ofany test lot are not in conformance with the requirements ofthis specification, the lot may be retested at the option of the manufacturer. The frequency of the retest will be double the initial number of tests and if the results of the retest conform to the specification, then the retest values will become the test values for certification. All test values, original and retest, shall be reported to the purchaser.
15.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding methods of Practice E29.
16.1 The manufacturer shall inspect the material covered by this specification prior to shipment. If so specified in the purchase order, the purchaser or his representative may witness the testing and inspection of the material at the place of manufacture. In such cases, the purchaser shall state in his purchase order which test he desires to witness. The manufac- turer shall give notice to the purchaser as to the time and place of the designated tests. If the purchaser’s representative does not present himself at the time agreed upon for the testing, the manufacturer shall consider the requirement for purchaser’s inspection at place of manufacture to be waived.
16.2 The manufacturer shall afford the inspector represent- ing the purchaser, without charge, all reasonable facilities to satisfy him that the material is being furnished in accordance with this specification. This inspection shall be so conducted as not to interfere unnecessarily with the operation of the works.
17.1 Rejection for failure of the material to meet the requirements of this specification shall be reported to the manufacturer within 60 calendar days from the receipt of the material by the purchaser. Unless otherwise specified, rejected material may be returned to the manufacturer at the manufac- turer’s expense, unless the purchaser receives, within 3 weeks of the notice of rejection, other instructions for disposition.
