Dental rotary instruments — Nominal diameters and designation code number
Specifies the relevant characteristics of the working parts of dental rotary instruments, e.g. burs, laboratory burs, grinding instruments, diamond instruments, mandrels, etc. It does not cover the diameters of root canal instruments.
Preparation of steel substrates before application of paints and related products — Tests for the as...
Describes a method for assessment of chloride-containing salts that are readily soluble in water and are present on a steel surface or on a previously coated surface. The method cannot be used on surfaces treated with chromate or nitrite. An iron(III) ion concentration of 10 mg/l also interferes with the determination. Warning: The substances and procedures used in this method may be injurious to…
Tractors and machinery for agriculture and forestry — Guards for power take-off (PTO) drive-shafts —...
Specifies the requirements and the laboratory test methods for determining the resistance against wear of guards. If this wear test is to be carried out, it shall be undertaken on the same guard but before the strength test (in ISO 5674-1).
Rubber and rubber products — Confidence intervals of repeatability and reproducibility values determ...
Describes a method for obtaining confidence intervals for the unknown precision values. On the assumption of normal distribution the confidence intervals are stated with a preselected error probability of 0,10.
Soils - Moisture-Density Relations Modified Proctor Test
1. OBJECT AND SCOPE OF APPLICATIOn
The present standard describes the method to determine the relation between the

Establishes a consistent, repeatable means of evaluating characteristics of falling-object protective structures under loading and prescribes performance requirements for these structures under such loading in a representative test. Applies to the following types of operator-controlled machines: a) crawler loaders, wheel loaders and backhoe loaders, b) crawler tractors and wheel tractors, c)…
1.1
Outlines the details of construction, marking, and testing of portable
electrical instruments for sensing the presence of toxic gas(es) and/or oxygen
concentrations in air. These instruments may be used in Class I hazardous
locations and gaseous mines in accordance with the Rules of the Canadian
Electrical Codes, Parts I and II.
1.2
This Standard applies to battery-operated…
Implants for surgery — Partial and total hip joint prostheses — Part 6: Determination of endurance p...
Describes test methods for determining the endurance properties under specified laboratory conditions. Specifies the principle, the reagents and materials, the apparatus, the procedure, the test report and the disposal of test specimens.
Measurement microphones - Part 2: Primary method for pressure calibration of laboratory standard mic...
Applies to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphones having the same mechanical dimensions or specifies a primary method of determining the pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure.
This publication supersedes IEC 60327.
