ISO 648:2008 specifies metrological and constructional requirements for volumetric pipettes with one mark (total delivery) and for volumetric pipettes with two marks, both of which are adequate for general laboratory purposes.
The details specified are in conformity with the principles of design and construction of volumetric glassware given in ISO 384.
Recommendations for small renewable energy and hybrid systems for rural electrification - Part 9-6: ...
IEC 62257-9-6:2008(E) proposes a simple selection procedure and cheap, comparative tests which can be performed in laboratories of developing countries, in order to identify the most suitable model of small Photovoltaic Individual Electrification Systems (PV- IES) up to 500 Wp for a particular rural electrification project from a number of products submitted for test. The tests provided in IEC…
Paper, board and pulps — Determination of dry matter content — Oven-drying method
ISO 638:2008 specifies an oven-drying method for the determination of the dry matter in paper, board and pulp.
The procedure is applicable to paper, board and pulp which does not contain any appreciable quantities of materials other than water that are volatile at the temperature of 105 °C ± 2 °C. It is used, for example, in the case of pulp, paper and board samples taken for chemical and…
ISO 25537:2008 specifies the minimum quality requirements (regarding optical, visual and edge faults) and durability tests for silvered float glass for internal use in buildings.
ISO 25537:2008 applies only to mirrors from silvered glass manufactured from flat, annealed clear or tinted float glass, from 2 mm to 6 mm thick, and supplied in stock/standard sizes and as-cut finished sizes to which no…
Rubber, vulcanized or thermoplastic — Determination of ageing characteristics by measurement of stre...
ISO 6914:2008 describes three methods for the measurement of the change of stress in a test piece at a given elongation for the purpose of determining the ageing characteristics of a rubber.
Method A is intended for measurement under continuous strain conditions.
Method B is the preferred method for measurement under intermittent strain conditions.
In the case of both methods A and B, a stress…
Radiation protection — Performance criteria for laboratories performing cytogenetic triage for asses...
ISO 21243:2008 is to give an overview of the minimum requirements of process and quality-control components of the cytogenetic response for triage of mass casualties. Cytogenetic triage is the use of chromosome damage to evaluate approximately and rapidly radiation doses received by individuals in order to supplement the early clinical categorization of casualties. ISO 21243:2008 concentrates on…
ISO 3471:2008 specifies performance requirements for metallic roll-over protective structures (ROPS) for earth-moving machinery, as well as a consistent and reproducible means of evaluating the compliance with these requirements by laboratory testing using static loading on a representative specimen.
ISO 3471:2008 is applicable to ROPS intended for the following mobile machines with seated…
Acoustics and vibration — Laboratory measurement of vibro-acoustic transfer properties of resilient ...
ISO 10846-1:2008 explains the principles underlying ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5 for determining the transfer properties of resilient elements from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. It is applicable to resilient elements that are used to reduce
the transmission of audiofrequency vibrations (structure-…
Acoustics and vibration — Laboratory measurement of vibro-acoustic transfer properties of resilient ...
ISO 10846-2:2008 specifies a method for determining the dynamic transfer stiffness for translations of resilient supports, under specified preload. The method concerns the laboratory measurement of vibrations on the input side and blocking output forces and is called “the direct method.” The method is applicable to test elements with parallel flanges (see Figure 1).
Resilient elements, which are…
