Description
Test weight class M1, cast iron, black, 5000 g ± 250 mg is a precision calibration mass intended for checking and adjusting laboratory and industrial scales. With a nominal value of 5000 g and a maximum permissible error of ± 250 mg, it corresponds to OIML accuracy class M1. The body is made of cast iron and finished in black for durable everyday use in weighing and quality-control areas. Design and metrological properties follow the recommendations of OIML R-111. The weight is supplied without a protective case and without a certificate, which suits applications that call for an uncased class M1 working standard. This test weight from manufacturer Labbox is part of the METRIA product type and comes as a single piece with a net weight of 5,000 kg. It is well suited to balance verification, comparative mass work and teaching laboratories that specify cast-iron M1 weights at the 5 kg level. The defined tolerance and robust construction support consistent calibration routines in line with established international recommendations for reference and working masses.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Precision weights, made of black cast iron, class M1, 5000 g ± 250 mg
What is this article?
Precision weights, made of black cast iron, class M1, 5000 g ± 250 mg is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Lab instruments.
A test weight is a mass of a stated class, used to check a balance. The class sets the tolerance. A weight that is dirty, or that has been handled with bare fingers, is no longer that class. The certificate ties the weight to a standard.
A balance compares a mass with a standard. An analytical balance reads to 0.1 mg or finer and needs a draft shield and a stable bench. A precision balance is coarser and faster. A platform scale takes a heavier load. The reading is only as good as the calibration chain back to the kilogram, which is why test weights and a certificate exist. A moisture analyser is a balance with a heater: it records the loss of mass as water leaves. The unit of mass is kept by the BIPM, compared across Europe by EURAMET, and accredited by BELAC. NIST publishes the same measurement foundations.
