    Abstract - (Show below) - (Hide below)

    Defines requirements for special design and other features of newly manufactured directly connected alternating current watthour meters with ratings up to and including 100 A l[max] for installation in domestic and small commercial/industrial premises.

    Scope - (Show below) - (Hide below)

    This British Standard specifies requirements for special design and other features of newly manufactured directly connected alternating current watthour meters with ratings up to and including 100 A I max for installation in domestic and small commercial/industrial premises.

    This standard is principally aimed at the UK market, although it might also be of use to other markets. Within the UK the standard is aimed at manufacturers who intend to design and market meters, meter operators engaged in meter installation activities and those involved in meter procurement, such as energy suppliers and meter asset providers.
