"Acetylene, the Principles of Its Generation and Use"

A complaint shall refer only to a
quantity of carbide remaining at the time of taking the sample.
"_Determination of Quality._
"1. In case the parties do not agree that the consignee is to send to the
analyst for the determination of the quality one unopened and undamaged
drum when the consignment is less than 5000 kilogrammes, and two such
drums when it is over 5000 kilogrammes, a sample for the purpose of
testing the quality is to be taken in the following manner:
"A sample having a total weight of at least 2 kilogrammes (= 4.4 lb.) is
to be taken. If the delivery to be tested does not comprise more than ten
drums, the sample is to be taken from an unopened and undamaged drum
selected at random. With deliveries of more than ten drums, the sample is
to be drawn from not fewer than 10 per cent, of the lot, and from each of
the unopened and undamaged drums drawn for the purpose not less than 1
kilogramme (= 2.2 lb.) is to be taken.
"The sampling is to be carried out by a trustworthy person appointed by
the two parties, or by one of the experts regularly recognised by the
German Acetylene Association, thus: Each selected drum, before opening,
is to be turned over twice (to got rid of any local accumulation of dust)
and the requisite quantity is to be withdrawn with a shovel (not with the
hand) from any part of it.
