![]() ![]() Some manufacturers ask the owner to register his product with the manufacturer so that the manufacturer can contact the owner directly in case of a safety problem. If the remedial action does not apply to all units, identification of individual units or a batch of units allows the manufacturer to limit his remedial action only to affected units. To limit the extent of remedy actions, the manufacturer or vendor may choose to include a serial number, date code, batch code, etc., marking. Identification may be the manufacturer’s or vendor’s name, trademark, or other equivalent identification.Īssociated with the manufacturer or vendor is the model number, model name, or equivalent also marked on the product. The manufacturer or vendor is identified by means of a marking on the equipment. Required behavior of the user to prevent injury In case of a safety problem with the product, the product manufacturer or vendor and model number must be identified so that the product owner or user may contact the manufacturer or vendor to remedy the safety problem. The standards often specify the test details and the acceptable peel strength force. If an adhesive label, a peel strength test is also performed. The acceptable degree of deterioration is subjective. After the tests, the marking or label is again visually examined for deterioration. The rubbing tests are on an actual or representative end-product surface. ![]() Rubbing has controlled pressure and time. Often, the test for permanency uses a mild solvent such as water, hexane, denatured ethyl alcohol, isopropyl alcohol, or other liquids, and then rubbing with a Q-tip, cloth, or equivalent, soaked with one or more of the liquids. After the environmental conditioning, the marking or label is visually examined for deterioration. Most standards specify tests to determine if the marking is legible and permanent.īefore testing, the marking or label is subjected to conditioning such as water immersion, high and low temperatures, chemical immersions, ultraviolet weathering, etc., that simulate the conditions that would be encountered in the intended use. However, there are standards that are expressly for markings and labels,. The marking and labeling requirements are primarily governed by end-product standards. Non-safety-related markings are not subject to the legibility and permanency requirements. Product markings related to the safety of the product must be legible and permanent (for the life of the product). Unless they apply to that part, markings shall not be put on parts that can be removed without the use of a tool. In general, product markings should be located near or adjacent to the part or region that is the subject of the marking. This paper addresses the safety-related markings and labels and explains the safety reasons for these markings. The markings can also provide warnings to avoid hazardous energy transfer to a body part. ![]() Markings and labelling on a product provide a multitude of information for safe installation and safe use of the product.
