NOTE Wristwatches using a tuning fork oscillator are subjected to these tests pending the availability of separate standards

which means it provides for classification using two systems – the first based on the chemical composition of all weld metal (paragraphs and tables carry the suffix letter A)

unevenly worn hooves

The proposed terms and definitions are directly issued from a scientific and technical analysis of the various stages and mechanisms involved in the alteration of plastics up to mineralization

Steel. Determination of the thickness of surface-hardened layers Ingestion-build-93833 NOTE Wristwatches using a tuning1 Scope This document specifies a method of measuring the case hardening depth, surface hardening depth, nitriding hardness depth and total thickness of surface hardening depth obtained, e. g. thermal (flame and induction hardening, electron beam hardening, laser beam hardening, etc.) or thermochemical (carbonitriding, carburizing and hardening, hardening and nitriding, etc.) treatment. NOTE Surface hardened layer can be produced by mechanical method
