Purpose of the development: Designed for visual diagnosis of local surface color changes in the presence of leaks Tetraoxide diazot (amyl) through the through defects of the piping connections of the fuel systems of launch vehicles.

Recommended application field: In rocket and space technology as visual means of detecting places 5 depressurization of joints of industrial hollow structures.

Technical characteristic: The color of the surface of the developer at the points of its contact with the leaks Tetraoxide diazotu is brown with some shades. The smallest leakage Tetraoxide diazot is reliably visually controlled by the developer during the test period of 5 minutes - about 10-7 m3 Pa / s. It can be used for its intended purpose in the temperature range +5 ... + 50 ° С and relative air humidity up to 98%

Advantages over analogues: Compared with other analogs, it has an order of magnitude higher sensitivity, it reliably reacts not only to diazo diazo, but also to the products of chemical transformations. Diazo is nitric dioxide, nitric and nitrous acid, suitable for use in tropical conditions.

The development stage readiness: Introduced in production

Description of the development:
()
It is made in the form of a tape, the geometric parameters of which are selected taking into account the dimensions of the pipeline connections. The original developer surface color is white. The color of the surface of the developer at the points of its contact with the leaks Tetraoxide diazotu is brown with some shades.
