GB/T 9445 NDT personnel qualification and certification GB/T 12604.7 Terminology for nondestructive testing Leak Detection GB/T 20737 Non-destructive testing - General terms and definitions3 Terms and DefinitionsTerms and definitions GB/T 12604.7 and GB/T 20737 apply to this document defined. 4. Summary Ammonia leak detection technology is the use of ammonia permeability to detect equipment leaks ammonia charging method has high sensitivity, can detect from Some small openings high pressure side to the low pressure side of the penetration of ammonia, and determine the location of the leak. Ammonia leak detection include the following three method. a) filled with 100% ammonia method, this method is not commonly used in the space charge ammonia detection equipment, the low charge ammonia pressure, and can pump it Leak detection vacuum of 93.7kPa about the case; b) filled with 10% to 30% (volume fraction) of ammonia, this method is commonly used in a large space filled ammonia detection equipment, and difficult to reach 93.7kPa vacuum leak detection or vacuum requirements to achieve higher cost of case; c) filled with 1% (volume fraction) of ammonia, this method commonly used in the subject device ammoniated much room situation.5 Safety requirementsThis chapter does not list all of the safety requirements for testing, the use of this standard user security guidelines should be established prior to detection. Detection process safety requirements include at least the following elements. a) detection testing personnel shall comply with the safety requirements of the scene, wear protective clothing and wear protection according to the relevant requirements of the detection site equipment; b) Ammonia is a flammable, explosive gas, the explosive limits of 15% to 18% (volume fraction), the site should be prepared to detect anti-static and fire Explosion-proof measures; c) ammonia toxic, and on-site testing personnel should be prepared to isolate the virus and operational measures; Electronic instruments d) should be of the fire and explosion function; ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32074-2015_English be delivered?Answer: Upon your order, we will start to translate GB/T 32074-2015_English as soon as possible, and keep you informed of the progress.
