Measurement microphones - Part 1: Specifications for laboratory standard microphones
Specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. Establishes a system for classifying laboratory standard condenser mocrophones.
Dental rotary instruments — Nominal diameters and designation code number
Specifies the relevant characteristics of the working parts of dental rotary instruments, e.g. burs, laboratory burs, grinding instruments, diamond instruments, mandrels, etc. It does not cover the diameters of root canal instruments.
Preparation of steel substrates before application of paints and related products — Tests for the as...
Describes a method for assessment of chloride-containing salts that are readily soluble in water and are present on a steel surface or on a previously coated surface. The method cannot be used on surfaces treated with chromate or nitrite. An iron(III) ion concentration of 10 mg/l also interferes with the determination. Warning: The substances and procedures used in this method may be injurious to…
Tractors and machinery for agriculture and forestry — Guards for power take-off (PTO) drive-shafts —...
Specifies the requirements and the laboratory test methods for determining the resistance against wear of guards. If this wear test is to be carried out, it shall be undertaken on the same guard but before the strength test (in ISO 5674-1).
Rubber and rubber products — Confidence intervals of repeatability and reproducibility values determ...
Describes a method for obtaining confidence intervals for the unknown precision values. On the assumption of normal distribution the confidence intervals are stated with a preselected error probability of 0,10.
