Scope

Tilting and swaying is a basic environment for electrical and electronic products placed on ships, and all kinds of products must withstand the effects of this environment. However, in terms of product adaptability and structural reliability, according to previous practice, not all electrical and electronic products installed on ships must undergo this environmental test. The inclination test is mainly applicable to products that must maintain normal or reliable operation when the ship is tilted at a large angle due to sea damage, maneuvering, unbalanced loading, wind, etc., and products that the tilting environment will have a significant impact on its performance. Such effects generally include: the destruction of the original force balance in the product system; the change of the bearing stress condition; the deterioration of the bearing lubrication condition; the abnormal operation due to the change of the internal free liquid surface position; the internal liquid leakage. The additional inertial force generated by the swing may cause additional dynamic loads to cause abnormal operation of the product or structural damage; lead to the destruction of the original force balance in the product system; change of bearing stress conditions; deterioration of bearing lubrication conditions; The position of the liquid level is turbulent, which leads to malfunction; the internal liquid leaks out. For products with working accuracy requirements in tilting and swaying environments, this test must be carried out. For products that have been confirmed to have no above-mentioned effects, this test may not be carried out after approval by relevant parties. For products that cannot be tested due to weight and other factors due to the above-mentioned effects, the treatment methods shall be in accordance with the relevant standards.
