This specification covers the chemical, mechanical, and metallurgical requirements for wrought titanium-12 molybdenum- 6 zirconium-2 iron alloy for surgical implants to be used in the manufacture of surgical implants. The heat analysis shall conform to the chemical composition requirements prescribed. Ingot analysis may be used for reporting all chemical requirements, except hydrogen. The wrought titanium-12 molybdenum-6 zirconium-2 iron alloy are classified as bar, forging bar and wire. The ultimate tensile strength, yield strength, elongation, and area reduction of the material shall be tested to meet the requirements prescribed.This specification covers the referee test methods for evaluating the performance characteristics of a single-use ureteral stent with retaining means at both ends, during short term use for drainage of urine from the kidney to the bladder. Ureteral stents shall be tested in accordance with the appropriate biological tests to meet the requirements prescribed. Retention strength, break strength, elongation, dynamic frictional force, and radiopacity shall be tested to meet the requirements prescribed.

Scope

1.1 This specification covers the referee test methods for evaluating the performance characteristics of a single-use ureteral stent with retaining means at both ends, during short term use for drainage of urine from the kidney to the bladder. These stents are typically available in diameters of 3.7 Fr to 14.0 Fr, and lengths of 8 cm to 30 cm, and are made of silicone, polyurethane, and other polymers. They are provided non-sterile for sterilization and sterile for single-use.

1.2 Exclusions—Long-term indwelling usage (over 30 days) is encountered with this product, but not commonly, and is therefore considered an exception to this specification. Similarly, the use of ureteral stents for non-ureteral applications such as nephrostomy and ileostomy is excluded from the scope of this specification. Non-sterile ureteral stents are also excluded due to the variability of hospital sterilization equipment and processes and the resulting effects on ureteral stent characteristics.

1.3 The following precautionary statement pertains only to the test method portion, Section 5, of this specification:

1.4 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
