Glass and glassware — Analysis of extract solutions — Part 6: Determination of boron(III) oxide by m...
The principle of the method specified is complexing of the boron in the extract solution to be analyzed with azomethine H, measurement of the optical density of the resulting colour complex by means of a molecular absorption spectrometer at 415 nm using 20 mm optical cells. Measures the concentration of boron, expressed as its oxide B2O3. Applies to the analysis of extract solutions obtained from…
Men's Smock (Hospital, Laboratory, Storemen and General Purpose) - Dimensions
1.1
This standard applies to the dimensions of hospital, laboratory, storemen and
general purpose smocks for wear by men.
1.2
Size dimensions cover 5 cm frequency chest girth sizing. An abbreviated range
(small, medium, large) is also indicated.
1.3
A maximum residual garment shrinkage of 2% has been recognized in specifying the
dimensions.
Fire tests — Full-scale room test for surface products
Specifies a test method that simulates a fire that under well ventilated conditions starts in a corner of a small room with a single open doorway. The method is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source. It is especially suitable for products that for some reason cannot be tested in a small laboratory scale, e.g.…
Truck and bus tyres — Verifying tyre capabilities — Laboratory test methods
Of the test methods presented (strength test for the structure, endurance test), only some may be required depending on the type of tyre to be tested. The tests are carried out in a laboratory under controlled conditions. Applies to all truck and bus tyres.
1 Scope
O437.0
1.1 This Standard pertains specifically to a class of mat-formed structural panelboards made predominantly of wood strands or wafers of a minimum and controlled length, a controlled thickness, and a variable or predetermined width, bonded together with a waterproof and boilproof binder.
1.2 These panelboards are intended, and used extensively, for construction applications…
Cinematography — Splices for use on 70 mm, 65 mm, 35 mm and 16 mm motion-picture films — Dimensions ...
Specifies dimensions and locations of transverse cemented or welded overlap splices and butt splices on one laboratory type and 4 projection types of film and print with magnetic or photographic sound records.
Toxicity testing of fire effluents — Part 5: Prediction of toxic effects of fire effluents
Reviews the progress of bioanalytical methodology, including the application of mathematical models which are available and may be used in the toxicological assessment of fire effluent atmospheres. Attention is also given to the application of such models as a means to minimize the use of laboratory animals in the testing of materials for fire effluent toxicity.
Test Method for Determining the Anaerobic Biodegradability of Plastic Materials
1.1
This Standard specifies the laboratory test method condition for determining
the anaerobic biodegradability of plastic materials on exposure to primary
anaerobic digestor sludge obtained from the treatment of primary clarifier
sludge at a municipal waste water treatment plant.
The degree and rate of anaerobic biodegradability of a plastic material in the
environment determines to what…
