Adhesives — Durability of structural adhesive joints — Exposure to humidity and temperature under lo...
This standard specifies the requirements and test methods for solid flat extruded sheets of impact-modified polystyrene (PS-I1) without fillers and reinforcing materials. This standard applies only to thickness 0,25 mm to 20,0 mm in accordance with clause 3. This standard also applies to PS-I sheet in roll form.
Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques - Section 15: Flick...
Gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to be constructed. A method is given for the evaluation of flicker severity on the basis of the output of flickermeters complying with this standard.
Miscellaneous lampholders - Part 1: General requirements and tests
Applies to lampholders of miscellaneous types intended for
building-in (e.g. used with general purpose lamps, projection lamps, floodlighting lamps and street-lighting lamps with caps and the methods of test to be used in determining the safe use of lamps in lampholders). Requirements for lampholders for tubular fluorescent lamps, Edison screw lampholders and
bayonet lampholders are covered by…
Application of IEC 60617-12 and IEC 60617-13 standards
Shows which choices can be made where IEC 60617-12 and IEC 60617-13 provide alternative techniques for the construction of graphical symbols that represent binary logic and analogue functions. Helps to create symbols having as consistent as appearance as possible, not depending on the originator, while still accurately representing the function. Furthermore, it establishes additional conventions…
Optics and optical instruments — Microscopes — Slides — Part 2: Quality of material, standards of fi...
This part of ISO 8037 specifies requirements and test methods for the quality of material, standards of finish and mode of packaging of silicate microscope slides for use in transmitted light microscopy in the visible spectrum range (400 nm to 760 nm).
Information technology equipment - Radio disturbance characteristics - Limits and methods of measure...
The intention of this standard is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions andinterpretation of results.
Plastics piping systems — Glass-reinforced thermosetting plastics (GRP) pipes — Test method to prove...
This International Standard specifies a method for testing the ability of glass-reinforced thermosetting plastics (GRP) pipes to withstand specified levels of initial ring deflection without displaying surface damage and/or structural failure.
