Acid value: Maximum 1,0. Further…
Textile Test Methods Quantitative Analysis of Fibre Mixtures -
Introduction
Laboratory methods for the quantitative analysis of mixtures of
textile fibres may be classified broadly as physical or chemical.
The most frequently employed physical method is mechanical
separation. This method is appli[Ccable only when each component
fibre in the fabric is confined to a different yarn. In such
cases, the composition can be determined simply by separating the
yarns and…
Insulating poles (insulating sticks) and universal tool attachments (fittings) for live working
Applies to insulating poles (insulating sticks), and tool attachments (fittings) and is divided into three chapters. Chapter I: Specifies the required characteristics for insulating poles with permanently attached fittings and the tests (electrical and mechanical) which should be satisfied by these tools. Chapter II: Specifies the required characteristics for parts which may be attached to and…
Caprolactam for industrial use — Determination of permanganate index — Spectrometric method
Equal volumes of potassium permanganate solution are added to a carpolactam test solution and to a blank (water). After standing for a specified time the absorbance, at a wavelength of 420 nm, of the test solution and of the blank are compared in cells of 5 cm thickness. The permanganat index is the difference between the absorbance of the test sample and that of the blank, multiplied by 100/3.…
Surface active agents — Sulfated ethoxylated alcohols and alkylphenols — Determination of content of...
From a methanolic solution of the test portion, the unsulfated matter is separated on an ion-exchange column (filled with a mixture of cation-exchange resins and anion-exchange resins). The unsulfated matter is recovered from the eluate by evaporation and weighing of the residue.
High-voltage switches. Part 2: High-voltage switches for rated voltages of 52 kV and above
Applicable to three-phase alternating-current switches, having making and breaking current ratings, for indoor and outdoor installations, for rated voltages 52 kV and above, and for rated frequencies up to and including 60 Hz.
