API SPEC 13A:2006 pdf download.Specification for Drilling-Fluid Materials.
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 calibrabon, mark each thermometer with 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 poor to first use by the manufacturer. Check calibration at least once per month for six months, then at least once per six months if required measurement capability is being maintained. If not, 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 calibration 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 recalibration is not required.
5.3.6 Motor-driven direct-indicating visconieters
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 Multimixer® Model 96 with 9829X 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 wtieriever a new batch of water is prepared or purchased, or
whenever delonizing cartridges are replaced.
5.3.9 Laboratory pressure-measuring devices
Manufacturer shall document evidence of laboratory pressure-measuring device calibration prior to placing into first use by the manufacturer and annually thereafter.
5.3.10 API Test calibration materials
Manufacturer shall test the applicable APl test calibration material(s) at least once per 40 tests. Sieve calibrationrequirements have been removed.
6 Packaged material
6.1Description
6.1.1 Packaging of palletized goods should safeguard the means of safe handling,transport,storage,andidentification, and minimize damage and spillage.Packed material should be inside the dimensions of the palletalthough some overhang is allowed.
6.1.2 This procedure applies to products covered by this International Standard. The main intention is to improvethe possible recycling of all packaging materials, including dry powdered or granular materials,not covered underthis internationai Standard, used in driling fluids, completion fluids and oil well cements.
