Paints and varnishes — Determination of resistance to humidity — Part 2: Condensation (in-cabinet ex...
ISO 6270-2:2017 specifies the general conditions and procedures which need to be observed when testing coated test specimens in constant condensation-water atmospheres or in alternating condensation-water atmospheres, in order to ensure that the results of tests carried out in different laboratories are reproducible.
NOTE The shape and preparation of the test specimens, the duration of the test…
Paints and varnishes — Determination of pH value — Part 1: pH electrodes with glass membrane
ISO 19396-1:2017 specifies a method for laboratory measurement of the pH value of polymer dispersions and coating materials using pH electrodes with a glass membrane. ISO 19396‑2 specifies a method for measuring the pH value using pH electrodes with ion-sensitive field-effect transistor (ISFET) technology.
Synchronous belt drives — Automotive belts — Determination of physical properties
This International Standard specifies test methods for determining the physical properties of synchronous belts
used in driving engine parts, such as camshafts, fuel injection pumps, balancing shafts. These test methods
are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated
and qualified by dynamic laboratory and field testing.
NOTE The…
Medical laboratories — Concepts and specifications for the design, development, implementation and u...
The proposed standard document specifies requirements for ensuring quality, safety and performance of laboratory-developed tests (LDT). It outlines the general principles and assessment criteria by which LDT shall be designed, developed, manufactured, validated and monitored for internal use by medical laboratories.
While the proposed standard follows a current best practice and state-of-the art…
Plastics — Determination of the aerobic biodegradation of plastic materials exposed to seawater usin...
This document describes a laboratory test method to determine the aerobic biodegradation of plastic materials exposed to seawater using accelerated conditions.
Furthermore, this document describes the general requirements of the apparatus and the procedures for using this test method. The biodegradation is determined by measuring the oxygen demand in a closed respirometer or by measuring the CO2…
Plastics — Marine biodegradation testing — Preparation of optimized intertidal seawater and sediment
This document specifies procedures for preparing seawater and sediments used in test methods to assess the biodegradation of plastic materials in the marine environment. The screened sediment and sediment-rinsed seawater are prepared to sustain aerobic testing at laboratory scale. The described method is designed to separate sediment-rinsed seawater and sand-gravel sediments from intertidal…
Molecular biomarkers — Detection of DNA in cotton used for textile production — Part 1: Extraction o...
This document provides requirements and recommendations to laboratories that perform PCR analyses of
cottonseed, leaf, cotton fibre and cotton fibre-derived materials. The following are within the scope of this
document:a) identifying the materials to be assessed, based on the probability of obtaining good quality, fit for
purpose DNA from the materials in subsequent steps in the cotton cloth…
Flexible and rigid cellular polymeric materials — Accelerated ageing tests
This document specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments.
Test conditions are only given for open cellular latex, both open-…
