When leak testing a low pressure chiller, it is recommended to use a maximum pressure of around 10 psi. This is a safe pressure that can help detect any leaks without risking damage to the chiller components. Always refer to the manufacturer's guidelines for specific pressure recommendations.
Nitrogen is not commonly used as a refrigerant in typical refrigeration systems. It is usually used in applications where an inert gas is needed, such as purging and pressure testing. Refrigerants like ammonia, CFCs, HCFCs, HFCs, and hydrocarbons are more common in refrigeration systems.
The bursting pressure of a high-pressure gas cylinder is typically calculated based on the material strength, thickness, and geometry of the cylinder, as well as the pressure rating it is designed for. Engineering calculations, such as the Barlow's formula or finite element analysis, are used to determine the maximum pressure the cylinder can withstand before failure. It is important to follow regulatory standards and guidelines when designing and testing high-pressure gas cylinders.
Liquid nitrogen does not impact the density of metals. Density is an intrinsic property of a material and is not affected by the temperature at which the material is in. Liquid nitrogen is often used in materials testing to cool down metals for a variety of reasons, but it does not change their density.

most plumbing codes require 10' of head for testing purposes. Maximum head pressure would depend on pressure rating of pipe & fittings used.
Refrigerant is not used for pressure testing because it is a specialized fluid used for cooling and is not an ideal medium for detecting leaks in a system. Refrigerant can be harmful to the environment if it leaks out, so using a different type of fluid, such as nitrogen or a specific leak detection solution, is preferred for pressure testing purposes.
Until you blow one up in controlled testing, you won't know. SAMMI publishes maximum pressures for cartridges that should not be exceeded.
The testing phase consumes the maximum effort in waterfall model.
There are 2 types of testing. Acceptance and Service. Acceptance testing is done by the manufacturer before it is shipped. Service testing is performed by the user periodically. Once a year. Service testing is for "in-service" hose to make sure it is maintained in optimum condition. Confirms that the hose is able to function at maximum pressure during firefighting operations. Guidelines are listed in NFPA 1962.

Nitrogen testing is done to check for the presence of nitrogen in various substances, such as soil or water. This test can provide valuable information about the quality and composition of the substance being tested, particularly for assessing environmental impacts or agricultural purposes. Nitrogen testing is important as nitrogen is a key element for plant growth and an essential component in various chemical processes.
Nitrogen balance is not important in the process of building muscle, but testing for nitrogen can help determine whether protein consumption is optimal.
