Inductor and transformer cores for telecommunications. Part 2: Sectional specification. Magnetic oxi...
Lists the characteristics, ratings and also the inspection requirements for magnetic oxide cores of assessed quality consisting of at least two parts forming a substantially closed magnetic circuit intended for inductors and timed transformers for professional and industrial applications. The cores covered by this specification may be used with an adjuster to provide a change of inductance for…
Ionizing radiation measurement systems with analogue or digital signal processing for thickness meas...
Deals with definitions and test requirements for ionizing radiation measurement systems designed for either continuous or discrete measurement and checks of thickness, mass per unit area, or mass per unit length on industrial processes, of material in such forms as sheets, coatings, laminates, tubes, or rods.
This publication replaces IEC 577 (1977).
Operating conditions for industrial-process measurement and control equipment - Part 3: Mechanical i...
Considers the specific operating conditions of vibration, shock, seismic and mechanical stress conditions to which land-based and offshore industrial-process measurement and control systems or parts of systems may be exposed during operation,
storage or transportation. Maintenance and repair conditions are not considered.

Acetic anhydride for industrial use — Methods of test
Gives general instructions and specifies methods of analysis. The methods to be used are determination of destillation yield, of bromine number, of arsenic content, of permanganate index, of dichromate index, the measurement of colour, titrimetric determination of acetic anhydride content, gravimetric determination of ash, spectrometric determination of phosphate content and visual limit tests…
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
This method is applicable to products having a dry residue after evaporation, greater than or equal to 0,005 % (m/m). The principleconsists in evaporation of a test portion in a platinum dish on a boiling water bath and drying of the residue in an oven at (105 +- 2) °C for 1 h. Replaces ISO Recommendation R 1900-1971.
