Implants for surgery — Partial and total hip joint prostheses — Guidance for laboratory evaluation o...
Guidance on the measurement of changings of the form, for instance wear and tear, creeping, plastic deformation, etc., and on available procedures when the test is performed in a simulator. Sensitivity, advantages, disadvantages and the measurement equipment of the different methods are compared in a table.
Safety requirements for electrical equipment for measurement, control and laboratory use - Part 3-04...
A technical report for use by test houses and other users. It assists them with determining and recording verification of conformity of the equipment under test with the requirements of IEC61010-2-043 (1997). If the paper version of the report is ordered, a diskette is provided with fill-in tables for recording the test results. If the report is downloaded directly from the web, it consists of…
Methods of Testing Pulp and Paper The Determination of Freeness
1.1
The Canadian Standard Freeness test is designed to give a measure of the
rate at which a dilute suspension of pulp may be dewatered. The drainage rate,
or freeness, has been shown to be related to the surface conditions and
swelling of the fibres, and is a useful index of the amount of mechanical
treatment given to the pulp.
1.2
The procedure was originally designed to yield a test value…
Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 4: So...
This document specifies a method to measure sound power by using sound intensity measurements on a measurement surface which encloses the sound source. This document provides guidelines on the acoustical environment, ambient noise, measurement surface, and number of measurements. The installation categories are generally designed to represent the physical orientation of a fan installed in…
Crude petroleum, petroleum products and related products — Determination of density — Laboratory den...
This document specifies a method for the determination, using an oscillating U-tube density meter, of the density of crude petroleum and related products within the range 600 kg/m3 to 1 100 kg/m3, which can be handled as single-phase liquids at the test temperature and pressure.
This document is applicable to liquids of any vapour pressure as long as suitable precautions are taken to ensure that…
