标准范围

本文件规定:a） 质量增益的测定；b） 当在360°C的水中或400°C或以上的蒸汽中进行腐蚀试验时，锆及其合金产品的表面检查；c） 在10.3兆帕的蒸汽中进行试验。本文件适用于锻造产品、铸件、粉末冶金产品和焊接金属。该方法已被广泛用于新合金的开发、热处理实践和焊接技术的评估。它适用于产品验收测试规定范围内的整体使用，而不仅仅是评估服务性能的手段。

This document specifies:a) the determination of mass gain;b) the surface inspection of products of zirconium and its alloys when corrosion is tested in water at 360 °C or in steam at or above 400 °C;c) the performance of tests in steam at 10,3 MPa.This document is applicable to wrought products, castings, powder metallurgy products and weld metals.This method has been widely used in the development of new alloys, heat-treating practices and for the evaluation of welding techniques. It is applicable for use in its entirety to the extent specified for a product acceptance test, rather than merely a means of assessing performance in service.
