Sludge recovery, recycling, treatment and disposal — Determination of calorific value of sludge
This Document specifies a method for the determination of the gross calorific value of sludge at
constant volume and at the reference temperature 25 °C in a bomb calorimeter calibrated by
combustion of certified benzoic acid.
The result obtained is the gross calorific value of the sample at constant volume with both the water of
the combustion products and the moisture of the sludge as liquid…

Information technology for learning, education and training — Language accessibility and human inter...
ISO/IEC 20016-1:2014 states the principles, rules and metadata elements for specifying language accessibility and Human Interface Equivalents (HIEs) in e-learning environments. It is structured to be able to support the requirements of applicable jurisdictional domains and in particular that of the UN Convention on the Rights of Persons with Disabilities.
Optics and optical instruments — Field procedures for testing geodetic and surveying instruments — P...
This part of ISO17123 specifies a field procedure for the verification that a given Global Navigation Systems (GNSS) -based system and measurement procedure meets a required measurement uncertainty at the location and time of interest. The field procedure uses three-dimensional coordinates which are compared to reference coordinates. It is designed to be applicable to the technically versatile…
Sludge and solid environmental matrices — Determination of dry residue or water content and calculat...
The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 °C and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and…
Fire resistance tests — Door and shutter assemblies — Part 1: General requirements
This document, used in conjunction with ISO 834-1, specifies a method for determining the fire resistance of door and shutter assemblies designed primarily for installation within openings incorporated in vertical separating elements, such as
— hinged and pivoted doors,
— horizontally sliding and vertically sliding doors, including articulated sliding doors and sectional doors,
— steel single-…
