Description
M1 block weight is a single test weight for calibration and verification tasks in laboratory and industrial weighing. It belongs to the M1 individual-weight range from 5 kg to 50 kg and is made of grey cast iron with a black lacquered finish. This unit offers a net weight of 20,000 kg and is supplied as 1 pc, giving a practical block format for larger denominations used on balances and scales that require M1 tolerance class. The cast-iron body provides a stable, durable mass reference for repeated handling on the bench or in production areas, while the lacquered surface helps protect the metal during storage and transport between workstations. Gross weight of the item is 20,500 kg. Typical applications include routine balance checks, quality-control weighing, metrology support and instrument qualification where an M1 class mass standard is specified. The block geometry is convenient for secure placement and straightforward visual identification in test-weight sets. Offered by manufacturer Sartorius, this grey-cast-iron block weight integrates cleanly into standard laboratory and industrial test-weight workflows without unnecessary complexity.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Block Weight 20 kg, OIML M1
What is this article?
Block Weight 20 kg, OIML M1 is the article on this page. Luminix Health distributes Sartorius 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.
