Plastics — Polymer dispersions — Determination of free formaldehyde
This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymer
dispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadiene
and vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersions
of other compositions.
Method A is the preferred method for polymer…
Water quality — Estimation of measurement uncertainty based on validation and quality control data
This International Standard specifies methods for the estimation of measurement uncertainty of chemical and
physicochemical methods in single laboratories based on validation data and analytical quality control results
obtained within the field of water analysis.
NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the
principles…
Welding — Calibration, verification and validation of equipment used for welding, including ancillar...
ISO 17662:2016 specifies requirements for calibration, verification and validation of equipment used for
- control of process variables during fabrication, and
- control of the properties of equipment used for welding or welding allied processes
where the resulting output cannot be readily or economically documented by subsequent monitoring, inspection and testing. This involves process…
Cranes — Competency requirements for crane operators (drivers), slingers, signallers and assessors
This International Standard gives competency requirements applicable for the selection, training, assessment and
verification of crane drivers (operators), slingers, signallers and their assessors.
This International Standard does not cover additional competency requirements needed for special operations, e.g.
man-lifting, pile-driving or pile-pulling.
NOTE 1 Responsibilities for the performance…
Digital imaging — Specification guideline for digital cameras
ISO 18383:2015 identifies a set of features that describes digital still cameras (DSCs), and it specifies their definitions, measurement methods, and presentation methods. This International Standard applies to DSCs designed and produced for and promoted to general consumers and need not be applied to those DSCs designed and produced to meet individual and special specifications agreed upon by…
Information technology — Virtual keyboards user interfaces — Part 1: General guidelines and recommen...
This document provides general requirements and recommendations for all forms of virtual keyboards including audio keyboards, on-screen or projected keyboards.
This international standard does not apply to physical keyboards that use real material keys or adaptable keys, which can be customized to user needs, for example with LCD display.
This International standard specifies requirements for dried lime (Citrus aurantifolia – Christm. – Swingle, Citrus latifolia Tanaka, family Rutaceae) in whole, slices and ground form.
The term "Dried Lime" includes dehydrated lime by sun and/or artificially dried.
Recommendation relating to storage and transport conditions is given in the annex A.
Manually portable (hand-held) powered lawn and garden equipment and forest machinery — Engine perfor...
Standardize a method for testing the performance and fuel consumption of internal combustion engines used to power manually portable (hand-held) powered lawn and garden equipment and forest machinery, including chain-saws, hedge trimmers, brush-cutters, grass-trimmers, pole-mounted pruners, and edgers. The document will replace ISO 7293:2021 and 8893:2021 when published.
