Flow-out and blow-out pipettes are considered. They will only be expected to provide their specified performance during the original operation. The requirements deal with the basis of adjustment, dimensions, delivery time and construction. The determination of accuracy and repeatability and the marking are specified.
Two types are specified: type I with graduation line and colour code which contains its volume when filled to the graduation line from the end away from the colour code, type II without markings wjich contains its volume when filled completely. Construction are shown in figures, the dimensions are tabled. The definition of capacity of each type is given and the determination of accuracy and…
Rubber, vulcanized — Determination of ageing characteristics by measurement of stress at a given elo...
Describes three methods of testing: A: measurements under continuous strain, B: preferred for intermittent strain, C: alternative to B under intermittent strain and laboratory conditions. For A and B a stress tester is used to record the stress at the temperature of ageing. Helpful for quality control. Measurement at differnt temperatures may be used for research. Method to be used depends on the…
Laboratory apparatus — Vocabulary relating to apparatus made essentially from glass, porcelain or vi...
In addition to terms used in the three official ISO languages (English, French, Russian) the equivalent ones are given in German. A list of sections and subsections is given followed by the names for items of apparatus. Closely all apparatus are accompanied by a drawing. The vocabulary has an index of the proper names used to identify some of the items and a multilingual index is included.
Liquid flow in open channels — Sediment in streams and canals — Determination of concentration, part...
In problems of sedimentation and sediment transport, a knowledge of the concentration and the characteristics of the sediment, such as particle size distribution and relative density, is of great importance. For this purpose, sediment samples are collected by suitable samplers and analysed in a laboratory. The results of the analysis are used in the calculation of sediment load, mean diameter and…
Acoustics — Measurements of sound insulation in buildings and of building elements — Part 9: Laborat...
Specifies a method for measuring a quantity called the suspended ceiling normalized level difference when the sound transmitted by paths other than the required paths is negligible.
Specification of the dimensional and other requirements, that are considered important to ensure the interchangeability of these instruments, for the nine most commonly used steel cutters. Other characteristics of cutters, for example spiralled blades or cross-cut, are not included. Attention is drawn to ISO 6360 which specifies a 15 digit number for the identification of all types of these…
