Qualification Code for Concrete Testing Laboratories
1. Scope
1.1 Scope
1.1.1 This Standard provides a means of determining the capability of a
laboratory to test concrete.
1.1.2 This Standard sets forth the following:
(a) The requirements for laboratory certification; and
(b) The administration of the certification program.
Copper alloys — Determination of nickel content — Gravimetric method
The method is applicable to the determination of nickel contents between 2 and 50 % (m/m). ISO 4742 specifies principle, reagents, apparatus, procedure, expression of results and test report. Normal precautions regarding the use of perchloride acid in laboratory work should be observed.
Cinematography — Projection reel size 7 for 8 mm Type S motion-picture film — Dimensions and specifi...
The size 7 reel descirbed here has a nominal film capacity of 15 m and is generally used for returning the film from the processing laboratory. It is considered to be interchangeable in all models of 8 mm projection cassettes (encapsulated devices) of type S which take up reels with a maximum outside flange diameter of 75 mm. This type of reel also fits normal reel-to-reel projection equipment.
The requirements deal with pipettes which are uncalibrated and intend for the transfer and dispensing of drops of solutions, and suspensions of biological materials. Two sizes are specified, details of which are given in a table, and the general form is illustrated in a figure. The resistance to sterilization by exposure to dry heat or to saturated steam is specified.
Joints in building — Laboratory method of test for air permeability of joints
Specifies the test method to be used in laboratories for assessing the air permeability of non-opening joints between components in the exterior walls of buildings, whether the joints have been subjected to prior ageing or not. Does not apply to joints within components (for example the joint between glass fixed in a window frame and sealed with a glazing compound).
Audiovisual, video and television equipment and systems. Part 10: Audio cassette systems
Lays down requirements for the track configuration on the compact cassette for language laboratory, language trainer, tape-slide synchronization systems or other similar applications. Specifies frequencies and durations of cue tones.
Equipment for continuously monitoring radioactivity in gaseous effluents. Part 1: General requiremen...
Applies to equipment for continuously monitoring radioactivity in gaseous effluents during normal operations and during anticipated operational occurrences. Does not deal with sample extraction and laboratory analysis. Specifies the general characteristics of the equipment, general test procedures, radiation, electrical, safety and environmental characteristics and the identification and…
