This Technical Report conforms to these steps

primarily in equipment-type specimens

hereafter referred to as the General Standard

The aim of the BS EN 311 is to provide best industry practices to demonstrate the strength of the wood-based panels

Timekeeping instruments. Wrist-chronometers with spring balance oscillator Ingestion-build-132972 Equipment characterization1 Scope This International Standard lays down the definition of the term chronometer, describing the categories, the test programme and the acceptable minimum requirements for wrist chronometers.
