Description
M1 block weight is a single test weight for calibration and verification of balances and scales in laboratory, production and service environments. It belongs to the M1 single-weight range covering nominal values from 5 kg to 50 kg and is produced in grey cast iron with a black lacquered surface for durable everyday handling. Net weight is 5,500 kg and gross weight is 6,000 kg; the article is supplied as 1 pc, making it straightforward to stock and deploy at the point of use. The solid block geometry sits stably on weighing platforms during adjustment, routine checks and quality-control procedures where M1 class performance is specified. From manufacturer Sartorius, this cast-iron reference mass supports metrology workflows that require a clearly finished, robust weight without complex accessories. Typical applications include balance verification in industrial labs, incoming inspection of weighing systems and periodic control of process scales. The lacquered grey-cast-iron construction is suited to professional use where mechanical strength and a defined accuracy class matter more than decorative finish. Non-sterile by design, it is intended for standard dry laboratory and workshop conditions rather than sterile or cleanroom protocols.
This article is part of Calibration & test weights, in Balances & scales.

Questions about Block Weight 5 kg, OIML M1, DAkkS
What is this article?
Block Weight 5 kg, OIML M1, DAkkS 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.
