Performance of portable leak detectors and of room monitors for halogenated refrigerants
The purpose of this European Standard is to qualify the performance of portable sniffing leak detectors and room monitors for halogenated refrigerants. These leak detectors are designed for the detection of CFC, HCFC, HFC and PFC halogenated gases, and their detection limit is checked with a calibration leak or calibration gas.

Ethanol as a blending component for petrol - Determination of inorganic chloride and sulfate content - Ion chromatographic method
This European Standard specifies an ion chromatographic (IC) method for the determination of inorganic chloride content in ethanol from about 1 mg/kg to about 30 mg/kg and of sulfate content in ethanol from about 1 mg/kg to about 20 mg/kg. NOTE Sulfate content can be determined from 0,5 mg/kg to 1,0 mg/kg. However, the precision was not established as no samples with sulfate content in this range were included in the interlaboratory test. WARNING - Use of this method may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Wood preservatives - Determination of the relative protective effectiveness of a wood preservative for use under a coating and exposed out-of-ground contact - Field test: L-joint method
This European Standard specifies a method for determining the relative protective effectiveness against fungal decay of a wood preservative applied to wood in combination with a subsequent surface coating, exposed to the weather and out of contact with the ground. The effectiveness is evaluated relative to a reference material. The method is applicable to the testing of commercial or experimental preservatives applied to non-durable timbers by methods appropriate to commercial practice and subsequently coated with a specified coating system. The method is applicable to products and processes used individually or in combination to prevent the development of decay in the wood. The method is also appropriate for factory finishing systems which include wood protection and wood preservation claims.

Wood preservatives - Accelerated ageing of treated wook prior to biological testing - Evaporative ageing procedure
This European Standard describes an evaporative ageing procedure, applicable to test specimens of wood which have been previously treated with a wood preservative, in order to evaluate any loss of effectiveness when these test specimens are subsequently subjected to biological tests.
