本标准描述了在100°F（38°C）条件下，温度调节器额定值最高可达1500 psi（10350 kPa）的推荐验证试验，以确保在制造商规定的温度或温度以下运行 额定压力。本标准涵盖1/4英寸NPS至8英寸的尺寸。本标准的目的是为制造商、用户、规范制定通用的压力等级指南，以促进一致的压力安全壳完整性。

This standard describes the recommended proof testing of temperature regulators with ratings up to a maximum of 1500 psi (10350 kPa) at 100°F (38°C) to ensure operation at or below the manufacturer's rated pressure. Sizes from 1/4 inch NPS up to 8 inches are covered by this standard.The purpose of this standard is to create common guidelines for establishing pressure ratings for use by manufacturers, users, specifiers and approval bodies in order to promote a consistent pressure containment integrity.
