Therefore, the first half of the 20th century, was a\u00a0period of intensified progress in diagnostic methods and techniques. A key one appears to be a\u00a0program created by the U.S. Joint Army, Navy and Air Force called JOAP (Joint Olive Analysis Program). This program was designed to standardize in the field of lubricant testing and is, by the US Army, still used, in an updated form, today.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <figure class=\"post__image-wrapper\"><img loading=\"lazy\" decoding=\"async\" class=\"post__image\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2022\/07\/silnik_lotniczy1.jpg\" alt=\"\" width=\"700\" height=\"742\" srcset=\"https:\/\/ecol.eu\/wp-content\/uploads\/2022\/07\/silnik_lotniczy1.jpg 700w, https:\/\/ecol.eu\/wp-content\/uploads\/2022\/07\/silnik_lotniczy1-283x300.jpg 283w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\"><figcaption class=\"post__paragraph post__paragraph--image\"><\/figcaption><\/figure>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">spectrographic examination of oil<\/h2>\n<p class=\"post__paragraph\">Military standards often enter general use. Not surprisingly, over time, oil testing has become a\u00a0standard in the technical evaluation of jet engines, piston engines or hydraulic systems in civil aviation, including in Poland. Since 29.08.2016, in accordance with Guideline No. 9 of the President of the ULC, spectrographic (elemental) testing is recommended during each planned oil change.<\/p>\n<h2 class=\"post__header heading heading--line\">certified laboratory and diagnosticians<\/h2>\n<p class=\"post__paragraph\">The amount of lubricant needed for laboratory analysis is only 50 ml. The correct way to take a\u00a0sample is presented in numerous documents or guidelines from engine manufacturers, e.g. Textron Lycoming Service Letter No. L171 czy Continental Aircraft Engine Standard Maintenance Practice Manual. The oil test is performed using the ICP (Inductively Coupled Plasma) technique according to the American ASTM D5185 standard, in an ISO 17025-accredited laboratory. The results obtained, should be evaluated by experienced specialists, especially in a\u00a0situation where only some engine manufacturers provide limits as to individual elements.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"774\" height=\"288\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-2.png\" alt=\"\" class=\"wp-image-25055\" srcset=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-2.png 774w, https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-2-300x112.png 300w, https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-2-768x286.png 768w\" sizes=\"auto, (max-width: 774px) 100vw, 774px\" \/><\/figure>\n<\/div>\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <p class=\"post__paragraph\">STLE (Society of Tribologists and Lubrication Engineers) or ICML (International Council for Machinery Lubrication), are organizations that bring together the world\u2019s top lubricant performance evaluation specialists.

A correct report must be accompanied by a\u00a0diagnostician\u2019s commentary \u2013\u00a0in the absence of manufacturer\u2019s guidelines, the diagnostician will evaluate the results and recommend possible corrective actions. The diagnostician also answers questions and concerns that may arise after the test. Through the evaluation of qualified specialists in the field of oil analysis, the user (CAMO) will be able to make an informed decision on the continued operation of the machine.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n      <\/article>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"890\" height=\"553\" src=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-3-ANG.png\" alt=\"\" class=\"wp-image-25060\" srcset=\"https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-3-ANG.png 890w, https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-3-ANG-300x186.png 300w, https:\/\/ecol.eu\/wp-content\/uploads\/2024\/05\/Diagnostyka-olejowa-tlokowych-silnikow-lotniczych-3-ANG-768x477.png 768w\" sizes=\"auto, (max-width: 890px) 100vw, 890px\" \/><figcaption class=\"wp-element-caption\">Sample laboratory report<\/figcaption><\/figure>\n<\/div>\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<section class=\"contact-bar alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <div class=\"offset-lg-2 col-lg-7 contact-bar__text\">\n\n        \n        \n          <p class=\"desc\">download sample lab report<\/p>\n\n        \n        \n          <a href=\"https:\/\/ecol.eu\/wp-content\/uploads\/2022\/11\/Przykladowy-raport-laboratoryjny-Ecol.pdf\" target=\"_blank\" class=\"btn btn--primary\">pobierz<\/a>\n\n        \n      <\/div>\n    <\/div>\n  <\/div>\n<\/section>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<section class=\"editor alignwide\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <article class=\"offset-lg-2 col-xl-9 col-lg-10 editor__text\">\n\n        \n          \n            \n\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t      \n\t\t\t\t\t\t      \t\t\t\t\t\t\t      <div class=\"post\">\n\t\t\t\t\t\t\t\t      <h2 class=\"post__header heading heading--line\">oil testing \u2013\u00a0greater flight safety<\/h2>\n<p class=\"post__paragraph\">Oil testing is a\u00a0helpful instrument in the maintenance process of aircraft engines.
