  "title": "The Weights Regulations 1986",
  "long_title": "These Regulations replace the Weights Regulations 1970 as amended. They apply to all weights for use for trade other than those used for weighing coins or currency notes or those used in connection with certain weighing equipment. They make provision as to the materials and principles of construction and marking of weights, testing, prescribed limits of error, stamping and obliteration of stamps. The Regulations prescribe weights for the purposes of section 11(1) of the Weights and Measures Act 1985 so that it is unlawful to use them for trade purposes unless they have been tested, passed as fit for such use and stamped by an inspector of weights and measures.",
