Conformity assessment — Guidance for drafting normative documents suitable for use for conformity as...
This document provides principles and guidance for developing normative documents that contain:
specified requirements for objects of conformity assessment to fulfil;
specified requirements for conformity assessment systems that can be employed when demonstrating whether an object of conformity assessment fulfils specified requirements.
This document is intended for use by standards developers…
Plastics — Strain rate dependent tensile tests for thermoplastics at ambient temperature
The proposed standard defines the general principles for determining stress-strain curves for plastics in a wide strain rate field, with a focus on data entry of material cards for finite element simulations in the event of transient loads (impact/crash). The procedure is to be used to investigate the strain rate dependent uniaxial tensile deformation behaviour of test specimens and to determine…
Fans — Laboratory methods of testing air circulating fans
This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…
Glass in building — Determination of the emissivity
This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass.
The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing.
The procedure, being based on spectrophotometric…
Café et dérivés du café — Dosage de l'acrylamide — Méthodes par CLHP-SM/SM et CG-SM après dériv...
Le présent document spécifie des méthodes de dosage de l'acrylamide dans le café et les dérivés du café par extraction à l'eau, purification par extraction en phase solide et dosage par CLHP-SM/SM et CG-SM. Il a été validé au cours d'une étude de validation de la méthode réalisée sur du café torréfié, du café soluble, des substituts de café et des dérivés du café dans des plages de…
Plastics — Polyethylene (PE) moulding and extrusion materials — Part 2: Preparation of test specimen...
ISO 17855-2:2016 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polyethylene (PE) moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given.
Procedures and conditions for the preparation of test specimens…
