Standard for Naval Engineering 713

The NES 713 test is well-liked and helpful for research and development as well as quality control. It assists in determining the levels of toxicity of material specimens that are rather small in size.

Infinita Labs have been consistently providing trustworthy results on every test we run since 1982, and as a result, we’ve established ourselves as a leader in the testing sector. Additionally, working with us gives you the peace of mind that comes from dealing with a laboratory that is ISO 17020, 17025, and 17065 accredited as well as a vendor that has been approved by the U.S. Navy, NAVSEA, and NSWC.

We have the technical expertise and industry experience you require for quality control, whether it be NES 713 or specially designed onsite testing.

The NES 713 Toxicity Test: What Is It?

Determine the potential toxicity of smoke, gasses, and particles that are produced when a small specimen of material is burned under controlled laboratory conditions with the aid of naval engineering standard 713, which is used by professionals tasked with designing, producing, and ensuring the quality of the newest maritime equipment.

The NES 713 exam is crucial for worker safety. Additionally, it offers a toxicity index of the numerous compounds emitted during combustion to producers and governing organizations.

NES 713 is fundamentally a test that ascertains how poisonous a specimen is in contrast to other known materials’ toxicity levels. It was created as part of the U.K.’s naval engineering standards. A sample is extensively burned in a control room with plenty of air to obtain accurate molecular readings from small specimens. NES 713 is a suitable test for experts tasked with quality control and/or research and development of materials used in naval equipment since it may capture findings that allow for the comparison of both synthetic and natural test materials.

The toxicity of a product or raw material can be determined by the test, however, the NES 713 combustion properties by themselves are insufficient to determine whether a specimen poses a fire risk in actual fire conditions. The toxicity values listed for a specimen on the toxicity index, however, are reliable and accurate results.

The NES 713 Toxicity Index

The toxicity index is a numerical totalization of the individual gas toxicity factors as they are formed during the total combustion of a test specimen under controlled circumstances. By determining how much of a certain gas is created when 100 grams of test material are burned in a volume of one cubic meter of air, the toxicity factors may be calculated.

Test apparatus. Our setup for NES 713 includes a robust combustion chamber that is fire-resistant, a separate combustion control unit, and a very precise gas analysis system. Full control is maintained over the ignition, burn periods, gas reactions, and air extraction throughout the entire combustion process.
