Gives definitions for standard degrees of protection provided by enclosures; protection of machines against harmful effects due to the ingress of water; protection of machines against ingress of solid foreign objects; protection of persons against contact with or approach to live parts and against contact with moving parts. Gives designations for these protective degrees and tests to verify that…

IEC 60915:2006 contains preferred dimensions for shaft ends and bushes and for the mounting of single-hole, bush-mounted, shaft-operated variable capacitors, variable resistors and potentiometers. If other dimensions not listed in this standard have to be used, it is recommended to select them also from IEC 60390 and IEC 60620. This second edition cancels and replaces the first edition published…

ISO 12213 specifies methods for the calculation of compression factors of natural gases, natural gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as a gas. It is divided into three parts: this part, ISO 12213-3:2006, specifies a method for the calculation of compression factors when the superior calorific value, relative density and…

ISO 21415-2:2006 specifies a method for the determination of the wet gluten content of wheat flour (Triticum aestivum L. and Triticum durum Desf.) by mechanical means. This method is directly applicable to flour. It is also applicable to semolina and wheat after grinding, if their particle size distribution meets the specification given.

ISO 11890-2:2006 is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. It specifies a method for the determination of the volatile organic compound (VOC) content of paints, varnishes and their raw materials. ISO 11890-2 is preferred if the expected VOC content is greater than 0,1 % by mass and less than about 15 % by mass. When the VOC…
