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.
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.
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.
1. Scope
1.1 This Standard pertains to temperature-raising water baths used in
biomedical laboratories.
1.2 This Standard includes construction, performance, and disclosure
requirements for water baths.
Fire tests — Small chimneys — Testing at elevated temperatures
Specifies a laboratory method of test. This test is designed to test for tightness, heat insulation and mechanical strength under standard conditions and for durability against treatment such as may occur during sweeping. This test provides information on the performance under a set of prescribed temperatur and flow rate conditions, but does not provide information appropriate to specific heating…
