Leather — Laboratory samples — Location and identification
Description of test pieces for whole hides and skins, sides and backs, bends (butts), sholders, bellies. Mass, storage and labelling of laboratory samples are given. Method is applicable to all types of leather, derived from mammals and prepared by all types of tannage.
Glycerols for industrial use — Methods of sampling
The procedures are applicable to crude or refined products in the course of filling, or to products already contained in drums or in transportable or fixed tanks. Owing to the heterogeneity of the lots it is recommended to adopt the sampling during filling. Specifies particular precautions in view of the very hygroscopic nature of the product. The principle consists in samplings, at regular…
Analogue voltage ranges and logic levels for mains operated nuclear instruments.
Applies to all mains operated nuclear electronics instruments used in research laboratories, radiation detectors excepted, and establishes standard voltage ranges and maximum permissible output voltages for analogue signals and output impedances for analogue circuits.
Air dielectric rotary variable capacitors. Part 1: General requirements for tests and measuring meth...
Describes tests that establish, as far as possible under laboratory conditions, their suitability for use and their ability to withstand specified conditions of mechanical shock and rigours of normal assembly processes. A guide to the use and testing of air dielectric rotary variable capacitors is given in an appendix.
Applies to new voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz.
The general requirements apply to all voltage transformers, but, for certain types, e.g. capacitor voltage transformers, the requirements are subject to the modifications stated in the appropriate chapter. Although the requirements relate…
Lays down the conditions and procedure for carrying out impulse tests on cables and their accessories, with a view to rationalizing the practice in different laboratories, and thus to facilitate valid comparisons between the results obtained on cables made to different specifications.
Notes:
1.This publication should be read in conjunction with IEC 60060 and 60141.
2.For voltage measurements…
Construction and Test of Electrically Equipped Machine Tools
1. Scope
This Specification applies to machine tools, not portable by hand, (but which may have certain portable parts), having electrical equipment mounted thereon and designed to be installed and employed in accordance with the rules of Part I of this Code.
It does not apply to:
(a) Machine tools which produce hazardous atmospheres due to their operation and therefore require the…
Paper and Pulp — Deinkability test for printed paper product mixtures containing woodfree printed pa...
This document specifies a basic laboratory test method for deinkability of woodfree printed paper products under alkaline conditions by means of single stage flotation deinking and fatty acid-based collector chemistry. The woodfree printed paper product of interest is tested as a mixture containing 10% by weight of the woodfree printed paper with the balance comprising a mixture of mechanical…
