Road vehicles — Brake linings — Seizure to ferrous mating surface due to corrosion — Test procedure
Specifies a laboratory method for conditioning brake linings in an environment that will promote corrosion, and a test method to assess the strength of bond formed by corrosion. For comparison of lining behaviours, it is essential that the material and condition of ferrous mating surfaces be constant and repeatable. Applies to drum brake linings and disc brake pads fitted to the brakes of road…
Alpine skis — Determination of the elastic properties
Specifies laboratory measurement methods to determine the elastic properties of alpine skis. Its purpose is to calculate the resistance of defined parts of the ski to bending and torsion.
Surface active agents and detergents — Methods of sample division
A bulk sample is reduced by a mechanical process until a reduced sample is obtained. The reduced sample may be used for the following purposes: a) the preparation of a final sample or a laboratory sample of mass greater than 250 g from a blended bulk sample of mass greater than 500 g; b) the preparation of several equivalent laboratory samples and/or reference samples and/or storage samples, each…
Gives the practical directions for the sampling of metallurgical coke from which breeze has been removed, for the determination of any property for both routine and special purposes; the sampling of breeze, or small coke nominal top size 20 mm or less; preparation of a miosture sample and of a laboratory sample for the determination of ash and other properties.
An international acceptable series of cylinders with a graduated scale and either a pouring spot or a stopper is specified. They are suitable for general laboratory purposes. The requirements for adjustment, accuracy, construction of the cylinder with design, material and dimensions are given. Graduation, figuring and inscriptions are specified and illustrated by drawings.
Contains information on the apparatus required, constitution of lots, the method of taking increments, bulk samples, laboratory samples, packing and labelling of samples, storage and despatch of samples, and the data to be included in the sampling report.
The method is intended with a view to determining the quality or particular characteristics of the goods. It describes the preparation of a lot, an increment, a bulk sample, a reduced sample and the laboratory sample, further packaging and handling of the samples.
Fresh concrete — Determination of the consistency — Slump test
Specifies a method for determining the slump of fresh concrete both in the laboratory and in the field. The method is applicable to plastic and cohesive concrete. It is not applicable when the maximum size of aggregate is greater than 40 mm. Describes also apparatus, procedure, expression of results, and test report.
