Marine Instrument Environmental Test Methods

Heavyweight|The two standards of "Marine Instrument Environmental Test Methods" drafted by Urit Testing have been authoritatively issued by the State Administration for Market Regulation!


Recently, the "Marine Instrument Environmental Test Method Part 8: Temperature Change" and "Marine Instrument Environmental Test Method" were compiled by the National Marine Standards and Metrology Center, the Institute of Marine Instruments and Meters of the Shandong Academy of Sciences, and Shenzhen Urit Testing Technology Co., Ltd. Part 10: Salt Spray Test" was officially released.

"Marine Instrument Environmental Test Method Part 8: Temperature Change" specifies the test requirements, test method selection, stepped temperature change, rapid temperature change and related information for the temperature change test of marine instruments. This part is suitable for assessing or determining the adaptability of marine instruments under temperature change conditions, and can also be used as a reference for temperature change environmental tests of its parts and components.

The formulation of the "Marine Instruments Environmental Test Methods Part 8: Temperature Changes" firstly paid attention to maintaining the advancement of the latest domestic and foreign environmental test technologies and the latest developments of marine instruments; adhered to the continuity with the original industry standards, and paid attention to the correlation. The coordination of national and industry standards emphasizes the applicability of actual production and environmental testing of domestic marine instruments.

Advancement: This formulation has carried out the latest version of "Environmental Test" in IEC (International Electrotechnical Commission), US military standard MIL-STD-810G "Environmental Test Method and Engineering Guidelines" and the latest version of national standard GB/T2423 and military standard GJB150A The research, combined with the latest technological achievements of the current marine instruments and actual environmental test conditions, continues to quote the latest tailoring technology for laboratory environmental tests under the US military standard to achieve the optimization of the sequence of test items and the scientific determination of test conditions. The classification of marine instrument environmental tests and the selection of test items have been added, and the advanced nature of the standards shall be reflected as much as possible on the basis of reasonable consideration of the environmental stresses borne by marine instruments and the existing characteristics of marine instrument environmental tests.

Continuity: The industry standard of HY016-1992 "Basic Environmental Test Methods for Marine Instruments", as a general basic standard for marine environmental testing, has a universal guiding significance for assessing the environmental adaptability of marine instruments. On the basis of continuing past experience, in 2007 we re-compiled the GB/T 32065-2015 "Marine Instrument Environmental Test Method" series of national standards, and completed the release and implementation of the first 7 items. In addition, three more national standards were submitted for approval in 2018, and they are currently in the stage of typesetting to be released. The eighth part of this compilation is one of the important parts of the new series of marine instrument environmental test national standards. It is an improvement to the original series of standards while adhering to the principle of continuity.

Applicability: While adhering to the advanced nature of the standard, this formulation fully considers the applicability of the standard, that is, combined with the current world-wide marine survey and monitoring and research requirements of scientific research, quality control requirements, technical status, and marine environment characteristics, and supplement The test conditions have been improved, vibration modes have been added, and efforts have been made to make the standards more operability and applicability.


Reliability Test


"Marine Instrument Environmental Test Method Part 10: Salt Spray Test" specifies the test requirements, test process and related information for the salt spray test of marine instruments and components. This section is applicable to assess the salt spray corrosion resistance of marine instruments and components and the influence of salt spray on the performance and functions of marine instruments and components.


The formulation of "Marine Instrument Environmental Test Methods Part 10: Salt Spray Test" focuses on maintaining the relationship with the latest domestic and foreign environmental testing technology and the latest quality control requirements of marine instruments; emphasizes the relationship between the actual production and use of domestic marine instruments applicability.


Advancement: This formulation is a reference to GB2423.18-99 "Environmental Testing of Electrical and Electronic Products Part 2: Test Kb: Salt Spray, Alternating (Sodium Chloride Solution)", IEC68-2-11 "Environmental Testing Part II Test method Ka: Salt spray, GJB4.11-83 “Salt spray test for the environmental test of ship electronic equipment” and GJB150.11A-2009 “Salt spray test for the environmental test of military equipment” and other latest test technologies have been studied and combined with the ocean The product characteristics and actual environmental test conditions of the instrument optimize and scientifically select the test technology and test conditions. On the basis of reasonable consideration of the environmental stress that the marine instrument actually bears and the characteristics of the marine instrument itself, try to reflect the standard Advancement.


Continuity: HY016.10-1992 "Marine Instrument Basic Environmental Test Method Test Ka: Salt Spray Test" as a general basic standard for marine instrument environmental testing has played an important guiding significance in assessing the environmental adaptability of marine instruments. Therefore, The formulation of the national standard retains the reasonable part of the original standard and upholds the principle of continuity.


Applicability: While adhering to the advanced nature of the standard, this formulation fully considers the applicability of the standard, that is, combined with the current scientific research requirements, quality control requirements, technical status, and characteristics of the marine instrument market in China to supplement and improve the test conditions. Try to make the standard more operable and applicable.
