The United States Government has adopted, and is exercising legitimatecontrol over the certification marks “JAN“ and “J“, respectively, to indicate that items so marked

35、oridentified are manufactured to, and meet all the requirements of specifications. Accordingly, itemsacquired to and meeting all of the criteria specified herein and in applicable specifications shall bear the certification mark “JAN“ except that items too small to bear the certification mark “JAN“

36、shall bear theletter “J“. The “JAN“ or “J“ shall be placed immediately before the part number except that if suchlocation would place a hardship on the manufacturer in connection with such marking, the “JAN“ or “J“may be located on the first line above or below the part number. Items furnished under

37、 contracts ororders which either permit or require deviation from the conditions or requirements specified herein or inapplicable specifications shall not bear “JAN“ or “J“. In the event an item fails to meet the requirementsof this specification and the applicable specification sheets or associated

38、 specifications, themanufacturer shall remove completely the military part number and the “JAN“ or the “J“ from the sampletested and also from all items represented by the sample. The “JAN“ or “J“ certification mark shall notbe used on products acquired to contractor drawings or specifications. The
