1.1 This International Standard specifies the methods to be used for the evaluation of natural calcium carbonate (chalk or limestone) ground to a dry powder for use in the rubber industry. NOTE 1 Classification of natural calcium carbonate according to fineness and chemical purity and typical physical and chemical properties for use in the rubber industry are given in informative annex D. NOTE 2…

1. Scope 1.1 General This Standard provides the requirements for materials and methods of construction for cast-in-place concrete and concrete precast in the field. Notes: (1) Requirements for the design of concrete structures are provided in CSa Standards A23.3 and S6. Design of some specialty concrete products is described in separate CSA Standards. (2) Methods of test for concrete are…

1 SCOPE This part of IEC 61243 is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1 500 V d.c. and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 v d.c.; voltage class B: up to and including 1 000 V a.c./1 500 V d.c.…
