500 gram steel calibration weight adjusted to ASTM Class 6 tolerance from general purpose applications.  Economically priced for those people that don't need all the paperwork proving accuracy typically for ISO requirements.  Instead this is a simple 500g steel mass with no storage case and is a popular choice for schools, universities, industrial, commercial and home use.  Ideal for routine weighing when precision tolerances are not required, but where economy is essential.  One-piece steel construction provides the maximum mass stability.

We don't recommend these weights for testing and calibration services requiring paperwork documentation to meet ISO requirements
and instead ask you to review our individual high precision laboratory weights or 9-piece or 21-piece calibration weights sets here.

Steel Calibration Weights from General Purpose Applications.

Individual masses available in a variety of weights.  Economically priced, these quality weights are adjusted according to ASTM Class 6 tolerance and are a popular choice for schools, universities, industrial, commercial and home use.  Ideal for routine weighing when precision tolerances are not required, but where economy is essential.  One-piece steel construction provides the maximum mass stability.

We don't recommend these weights for testing and calibration services requiring paper work documentation to meet ISO requirements.
.
If you are required to meet standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirement a NVLAP Certificate is needed meet the compliance requirements. You can see a 500g calibration weight with a NVLAP Cert is a LOT More Money but if this is what you need then you are fooling yourself buying this 500g ASTM 6 check weight below.

We always recommend you check with your regulatory or compliance officer to verify what quality or regulatory requirements must be meet before ordering any calibration weights. We always like to say when in doubt purchase weights with the NVLAP Certificate.

Choose from a comprehensive selection of weight sets or individually weights ranging from 30kg to 1mg. We offer Class 0 , Class 1, Class 2, and many more calibration weights at www.calibrationweight.com.

All calibration weights are not returnable.  The reason for this is some people think nothing to order calibration weights to calibrate their scale and then return the calibration weights since now their scale is all calibrated.  These are the same people that buy a ladder at Home Depot, paint their house using the ladder, and spill a few gallons on the ladder and then return the ladder telling Home Depot the ladder isn't quite what they expected.  Plus what are you mad about I'm returning the ladder in 10 days well under your 30 day limit.

It is truly sad and bad how many ruthless people there are and it seems the internet has a greater portion of people like this since the don't have to face a person and basically tell them thanks for letting me use the weights for free.
