This Japanese Industrial Standard specifies the requirements for certification pro-
cedure peculiar to ready-mixed concrete, quality control system of producte, etc. The
structure of this Standard is the same as the one of the general guidance on certifica-
tion system specified in JIS Q 1001 (hereafter referred to as "general guidance on cer-
tification system") and, of these requirements, those taken as special cases with a view
to the characteristics of the relevant industrial and mineral products compared with
the requirements specified in the general guidance on certification system are speci-
fied.
Besides, this Standard should be read together with JIS Q lO0l.
