Air testing is used where liquid media are not desirable, for example, when there is a risk of contamination or residual media such as oil and water. <\/p>\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Nitrogen test<\/h2>\n\n<p class=\"wp-block-paragraph\">Tightness testing with nitrogen in the pressure range of 25\u201350 bar. Nitrogen is also used after flushing to dry and inert the hose, and to ensure that the hose maintains the desired degree of purity. This is especially important when purity requirements are in accordance with NAS 1638 class 6 or equivalent standards for particle control.  <\/p>\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Hose flushing<\/h2>\n\n<p class=\"wp-block-paragraph\">Cleaning of hoses to remove contamination and particles before use. <\/p>\n\n<p class=\"wp-block-paragraph\">Offered as:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Water flushing<\/li>\n\n\n\n<li>Oil flushing (mineral-based)<\/li>\n\n\n\n<li>Flushing with glycol\/water-based fluid. <br\/>Particle samples are taken as needed and can be documented in accordance with NAS 1638 or ISO 4406.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading has-medium-font-size\">Retesting and condition monitoring<\/h2>\n\n<p class=\"wp-block-paragraph\">Used hoses are inspected and tested to assess further use.
