5.3 CalIbration Intervals
5.3.1 General
Any instrument subjected to movement which can affect its calibration shall be recalibrated prior to use.
5.3.2 Thermometers
Calibrate each thermometer before first use by the manufacturer. After cahbration. mark each thermomeler wth an identifying number that ties it to its corresponding correction chart, Check calibration annually against the secondary reference thermometer.
5.3.3 Laboratory balances
Calibrate each balance prior to first use by the manufacturer. Check calibration at least once per month (or six months, then at least once per six months if required measurement capability is being maintained, If riot, service and recalibrate, then check at least once per month until required measurement capability is maintained for six months, then once per six months.
5.3.4 Sieves
No cahbration of sieves Is required. See 5.2.11 for periodic measurement requirements using standard reference
matenals,
5.3.5 Hydrometer
Calibrate each hydrometer prior to its first use by the manufacturer. After calibration, note and record each hydrometer Identifying number that ties it to its correction chart. Periodic recalibratlon is not required.
5.3.6 Motor-drIven direct-indicating viscometers
Calibrate each viscometer prior to its first use by the manufacturer. Check calibration at least once per week for
three months, then at least once per month if required measurement capability is being maintained.
5.3.7 Mixer
EXAMPLE MuhimixerSi Model 98 with 9B29X impeller blades or equivalent, mounted flash side up.
Check and record mixer spindle speed at least once every 90 days to ensure operation within the prescribed range, using a phototachometer or similar device. Remove, clean, dry, and weigh each impeller blade in use at least once every 90 days. Record masses and replace blades when mass drops below 90 % of its original value,
5.3.8 DeionIzed (or distilled) water
Manufacturer shall determine hardness of water whenever a new batch of water is prepared or purchased, or whenever delonizing cartridges are replaced.
5.3.9 Laboratory pressure-measuring devices
Manufacturer shall doc*irnent evidence of laboratory pressure-measuring device calibration pnor to placing into first use by the manufacturer and annually thereafter.
6.4 Marking – Pallets
Markings should include the following where applicable and as specified by individual contracts:a)product name;
b)gross/net mass, in kilograms or pounds;
c)other information as required, such as manufacturer’s name, gross allowable mass, disposal options.6.5 Marking – Bags
Markings shall include the following where applicable and as specified by individual contracts:a)name of the material in print script at least 13 mm in height;
b) mass of the material in letters, or numbers and letters, at least 6 mm in height; the mass shall be listed in
killograms;
c)lotbatch number in print script and/or numbers at least 3 mm in height, traceable to manufacturer’s country of
origin;
d)identification as recyclable;e)safety information.
6.6Pallet covers
6.6.1 Each pallet may have a cover made of at least one of the following:a)polyethylene(PE) shrink or wrapped film;
b)PE bonnet type;
polypropylene (PP) bonnet type.
6.6.2 All plastics should be UV-stabiized, unless otherwise requested.Cardboard, carton, or wood covers maybe used in place of the above. If appropriate, a bottom layer of cardboard,PE sheet or plywood may be connectedto the cover to unitize the overall package.
6.7Package weight
Each sack shall contain a specified net mass ±2%.The average weight of 5 % of all sacks in a shipment, taken atrandom, shall not be less than the specified weight.
6.8Storage
The manufacturer shall advise on storage upon request.
