A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...
Resin identification code. The ASTM International Resin Identification Coding System, often abbreviated RIC, is a set of symbols appearing on plastic products that identify the plastic resin out of which the product is made. [1] It was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association) in the ...
A common nitrate test, known as the brown ring test [2] can be performed by adding iron (II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the presence of the nitrate ion. [3]
Materials may react violently with water or form peroxides upon exposure to air (e.g., potassium, sodium). 1. Materials that are normally stable but can become unstable (self-react) at high temperatures and pressures. Materials may react non-violently with water or undergo hazardous polymerization in the absence of inhibitors (e.g., propene). 0.
Massah ( Hebrew: מַסָּה) and Meribah ( Hebrew: מְרִיבָה, also spelled " Mirabah ") are place names found in the Hebrew Bible. The Israelites are said to have travelled through Massah and Meribah during the Exodus, although the continuous list of visited stations in Numbers 33 does not mention this. In Exodus 17:7, Meribah is ...
Ships and marine facilities must conform to an international standard for piping systems identification. This is ISO 14726:2008 Ships and marine technology — Identification colours for the content of piping systems. This is a two-colour banded marking system. The main colour shows what the fluid is being used for.
SmartWater consists of a liquid containing a code. The presence of SmartWater can be seen under ultraviolet light. It is intended to be applied to valuable items, so that if they are stolen and later recovered by police, their original owner can be determined after laboratory testing of a sample.
