  • ISO 15989-2004 - 中外标准 - - 2004/12 - 现行
    ISO 15989:2004 specifies a method of measuring the contact angle of water droplets on corona-treated polymer film surfaces and subsequently determining the wetting tension of the film. The method is applicable to practically any polymer film. It is not applicable, however, if the surface of the film exhibits a chemical affinity for water.

  • ISO 8009-2004 - 中外标准 - - 2004/10 - 作废
    ISO 8009:2004 specifies the minimum requirements and test methods to be used for reusable diaphragms made from natural rubber and silicone rubber. These diaphragms are intended for contraceptive use. ISO 8009:2004 is not applicable to other vaginal contraceptive barriers, such as those known as cervical caps, vaginal sponges and vaginal sheaths.

  • ISO 22048-2004 - 中外标准 - - 2004/8 - 现行
    ISO 22048:2004 provides a digital format to store, and transfer between computers, in a compact way, important calibration and instrumental-parameter data necessary to make effective use of spectral-data files from static SIMS instruments. This format is designed to supplement the data transfer format specified in ISO 14976.

  • ISO 6145-4-2004 - 中外标准 - - 2004/6 - 现行
    ISO 6145-4:2004 specifies a method for continuous production of calibration gas mixtures, containing two or more components, from pure gases or other gas mixtures by continuous injection of the calibration component(s) into a complementary gas stream by means of a syringe. If pre-mixed gases are used instead of pure gases (see Annex A), much lower volume fractions can be obtained. The volume flow rates, from which the volume fractions are determined, can be calculated from the individual flow rates and can be independently measured by a suitable method given in ISO 6145-1. The merits of the method are that a substantial quantity of the gas mixture can be prepared on a continuous basis and that multi-component mixtures can be prepared almost as readily as binary mixtures if the appropriate number of syringes is utilized, or if the syringe already contains a multi-component mixture of known composition. This method also provides a convenient means for increasing the volume fraction of the calibration component in the mixture in small steps. It is therefore a useful method for evaluation of other characteristics of gas analysers, such as minimum detection limit and dead zone, as well as accuracy. The relative expanded uncertainty in the volume fraction obtainable for a binary mixture (at a coverage factor of 2) is 5 % and the range of applicability is 10-5 to 10-2.

    GB/T 19502-2004 - 中外标准 - - 2004/4 - 现行
    本标准为采用辉光放电发射光谱法进行体材分析和深度剖析提供了方法通则。这里所讨论的方法通则仅限于刚性的固体样品的分析,不包括粉末、气体或溶液的分析。结合将来其他特定的标准方法,本方法通则应能够实现仪器的规范管理和测量条件的控制。  尽管在近年来有不同类型的辉光放电发射光源问世,但本通则中仍以Grimm型光源为例。这是因为考虑到目前在用的辉光放电光谱仪绝大多数采用Grimm型光源。应该明确的是,本通则包含的条款同样适用于其他类型(如Marcus型)的光源,Grimm型光源仅作为一个实例。
