Reusable containers for refrigerants under high pressure should be tested and date stamped at least every 5 years as per regulations such as DOT or ASME standards. This ensures the safety and integrity of the container for continued use with high-pressure refrigerants.
They could only be strength tested by subjecting them to very large amounts of pressure, but you would not be able to do in depth molecular tests without chemicals in a lab. (besides looking at the sample under a microscope)
Your heart, that is part of the cardiovascular system is tested with EKG or ECG test.
GFCI outlets should be tested monthly to ensure they are working properly. This can be done by pressing the "Test" and then "Reset" buttons on the outlet. If the GFCI does not trip when tested, it may need to be replaced.

Reusable containers for refrigerants under high pressure should be tested and date stamped at least every 5 years as per regulations such as DOT or ASME standards. This ensures the safety and integrity of the container for continued use with high-pressure refrigerants.
Reusable containers for refrigerants are required to be tested every 5 years as per industry standards to ensure they remain safe and effective for use. This testing includes checking for leaks, structural integrity, and compliance with relevant regulations to prevent potential hazards. Regular testing helps maintain the quality and safety of the containers, prolonging their lifespan and preventing accidents.
Diamonds are not stamped: perhaps the metal setting is stamped. Take your jewelery to a local jewelery shop and ask that the diamond be tested.
the maker of the tank, the pressure that it should operate at...eg (WP 228BAR)then the test pressure that the cyl is tested at (TP 350BAR)and the capacity the cylinder would hold if filled with water eg 12 L 12 litres
it means its not gold.....I just tested one with that stamp
the pressure we set for the injector and tested on machine
Tested to 10 feet of head pressure (static)
It means it is 14 karat gold by purity.It still needs to be tested to make sure its real gold.
i had my eyes tested and they want my blood pressure check cause they think i got tortuosity fundus what does that mean
Have it pressure tested and repair the leak.
The "J.Stevens" name was shortened to "Stevens" in 1940. What you need to look for is the chamber size, which should be stamped on the barrel. It needs to be 2 & 3/4 inches to shoot modern ammo. Also Stevens usually stamped near the chamber size if the barrel was proof tested. My Stevens single is stamped "Proof Tested Steel" and it handles modern ammo well, but kicks like a mule. To be really safe, let a gunsmith look at it.
It means nothing at all - if it is stamped Sterling that means it is 92.5 percent silver - if it has no writing or stamping on it - it may or may not be silver - it means you should have it tested by a professional so you don't accidentally blind yourself with acid
