Rubber footwear, lined industrial, for use at low temperatures
Defines the requirements to ensure that a sufficient degree of flexibility is retained to allow for comfort in wear. The tests refer to the hardness of soling and heel, the flexibility of the upper part of boots and marking. The Annex contains details to the apparatus, test pieces, procedure and the expression of the results. The suggestion of the apparatus is shown in two figures. Replaces the…
Shipbuilding — Numerical control of machines — ESSI format
Serves as a guide in the co-ordination of system design, to minimize the variety of programs required, to promote uniformity of programming techniques, and to foster interchangeability of programs between NC drawings and flame cutting machines used in the shipbuilding industry. The "ESSI format" may be used in connection with any data code for punched cards, punched tapes, magnetic…
Recommended Practice for the Prediction of Sound Pressure Levels in Large Rooms Containing Sound Sou...
1. Scope
1.1 This Recommended Practice describes a procedure for the prediction of sound pressure levels in a large room containing a number of sound sources. This procedure may be used to compute A-weighted, octave, or fractional octave band sound pressure levels over continuous contours, or at specific points, to predict:
(a) Sound pressure levels at the design stage;
(b) The…
Industrial-process control valves. Part 2: Flow capacity. Section Three: Test procedures
Applies to industrial-process control valves and provides the flow capacity test procedures for determining some of the variables used in the equations given in IEC 534-2.
Specifies requirements for industrial platinum resistance thermometer sensors suitable for all or parts of the temperature range -200°C to +850°C with two tolerance classes. It is primarily concerned with sheathed elements suitable for immersion in the medium to be measured. Describes methods of test and suitable apparatus for some of the tests.
Formsets for Use with Embossed Cards and Imprinting Equipment
1. Scope
1.1 The purpose of this Standard is to define common media for the transferring of information from sources, including the embossed characters on a card, by means of imprinting equipment.
1.2 The existence of two standards in relation to formset dimensions is recognized as are the several different methods of capturing the information contained on completed formsets.
1.3…
