Regulations for Safety Inspection of Existing Hazardous Machines and Equipment Article 16
If there has difficulty in performing the pressure test of the existing hazardous equipment, the Inspector may proceed with a substitutive test in accordance with the following requirements:1. To perform a hydraulic test at the pressure of 1.1 times the maximum operation pressure for the boilers or the steam pressure vessels.2. To perform a pressure test with respect to the contents or the harmless liquid contained therein, at the pressure of 1.1 times the normal operation pressure for the high pressure gas vessels, the super-low temperature vessels, the vessels containing special contents such as catalyst, or other vessels which appear to be difficult to receive a hydraulic test.In case there appears to be difficulty in performing the pressure test with liquid as stipulated in the preceding paragraph, a pressure test performed with air, nitrogen, or other harmless gases at the equivalent pressure may be used as a substitution.The pressure tests stipulated in the above two paragraphs may be exempted, if there are evidences by means of records to show that the same tests have been implemented and qualified within one (1) year.
中文原文 既有危險性機械及設備安全檢查規則第16條
檢查機構於實施既有危險性設備檢查之耐壓試驗有困難者，得依下列規定辦理：
一、鍋爐、蒸氣類壓力容器，以最高使用壓力一點一倍以上壓力實施水壓試驗。
二、高壓氣體類設備、超低溫設備、內存觸媒等特殊內容物之設備或其他實施水壓試驗有困難者，以常用壓力一點一倍以上壓力就內容物或無危害之虞之液體實施耐壓試驗。
前項耐壓試驗，以液體實施有困難者，得以同等壓力之空氣、氮氣或其他無危害之虞之氣體實施耐壓試驗。
前二項耐壓試驗曾於一年內實施合格，並有紀錄證明者，得免實施。
