## Table 2 Amounts of error for packages labelled by mass or volume

Column 1 | Column 2 | Column 3 |
---|---|---|

Stated quantity(g or ml or cm^{3}) | Amount of error(% of stated quantity) | Amount of error(g or ml or cm^{3}) |

More than 0 to not more than 50 | 9.0 | – |

More than 50 to not more than 100 | – | 4.5 |

More than 100 to not more than 200 | 4.5 | – |

More than 200 to not more than 300 | – | 9.0 |

More than 300 to not more than 500 | 3.0 | – |

More than 500 to not more than 1 000 | – | 15.0 |

More than 1 000 to not more than 10 000 | 1.5 | – |

More than 10 000 to not more than 15 000 | – | 150.0 |

More than 15 000 | 1.0 | – |

Note: For the purposes of this table, if the quantity is stated in units other than grams, millilitres, or cubic centimetres, the quantity must be converted into the equivalent number of grams, millilitres, or cubic centimetres, as appropriate. For example, if the quantity is stated in kilograms, litres, or cubic metres, the quantity must be converted into the equivalent number of grams, millilitres, or cubic centimetres, respectively. The table must then be applied accordingly. |

## Table 3 Amounts of error for packages labelled by reference to length, width, area, or number

Column 1 | Column 2 |
---|---|

Quantity type | Amount of error |

Length or width | 2% of stated length or width for all packages |

Area | 3% of stated area for all packages |

Number | For packages stated to contain 50 or less goods, 1 good |

For packages stated to contain more than 50 goods, 2% of the number of stated goods rounded up to the nearest whole number |
