Textile glass — Rovings — Basis for a specification
Is intended to serve as a guide for the establishment of technical specifications for products of given type. Rovings are divided in two main groups: - rovings that are chopped during subsequent operations - rovings that are utilized without being chopped The following particulars are mentioned and the relevant International Standards are quoted: Designation, type of glass, filament diameter,…
Chemical products for industrial use — Sampling techniques — Solid chemical products in the form of ...
From the lot to be sampled a certain number of increments is taken. The increments are mixed to form either a bulk sample or several primary samples, depending on the purposes of the sampling. By means of replicate reductions a reduced sample is prepared from the bulk sample or from each primary sample, then several laboratory samples, each stage of the division being preceded in each case by…
Butadiene for industrial use — Determination of active tert-butyl-catechol (TBC) (4- (1,1- dimethyle...
The active TBC in a test portion is extracted by mixing with a solution containing m-nitrophpenol (as the internal standard) and evaporating the butadiene. The TBC and m-nitrophenol are separated by high-performance liquid chromatography and detected by UV: The peak areas or peak heights are measured and the TBC content is determined by using a calibration graph. The polymerization inhibitor TBC…

Metallic and other non-organic coatings — Review of methods of measurement of thickness
This second edition cancels and replaces the first edition (i. e. ISO 3882:1978). Applies to both metallic and non-metallic substrates. It is limited to tests already specified, or to be specified, in International Standards, and excludes certain tests which are employed for special applications. Includes five non-destructive methods and four destructive methods.
Information Processing Systems - Open Systems Interconnection - Basic
Reference Model
This National Standard of Canada is equivalent to International Standard ISO
7498-1984.
1 Scope and field of application
This International Standard describes the Reference Model of Open Systems
Interconnection. It establishes a framework for coordinating the development
of existing and future standards for the interconnection of systems and is
provided for reference by those standards…
