7、revised; c) Clause 4 “Symbols and abbreviated terms” has been revised; d) specifications relating to the maximum weight of a lot or sub-lot have been modified; e) Clause 9 “Precision” has been given in more detail; f) in Annex A relating to the storing of samples (Part 9), it has been deleted that p
8、lastic bags shall not be used for samples smaller than 50 l; g) Annex J “Standard sampling plans for common situations” has been added; h) Annex K “Additional information about precision” and Annex L “Distribution of increments” (both informative) have been included; i) the Bibliography has been upd
