DS/ISO 3856/2:1982 色漆和清漆.“可溶性”金属含量的测定.第2部分:锑含量的测定.火焰原子吸收光谱测定法和若丹明B (Rhodamine B) 分光光度法

This part of ISO 3856 specifies two methods for the determination of the antimony content of the test solutions prepared according to ISO 6713 or other suitable International Standards.1) The methods are applicable to paints having "soluble" metal contents in the range of about 0,05 to 5 % (m/m). The flame atomic absorption spectroscopic (AAS) method (clause 3) should be used as the reference method. Other methods can be used by agreement between the interested parties. If a photometric method is agreed, the Rhodamine B spectrophotometric method (clause 4) should be used. In case of dispute, the AAS method should be used.

DS/ISO 3856/4:1982 色漆和清漆.“可溶性”金属含量的测定.第4部分:镉含量的测定.火焰原子吸收光谱测定法和极谱法

This part of ISO 3856 specifies two methods for the determination of the cadmium content of the test solutions prepared according to ISO 6713 or suitable International Standards.1) The methods are applicable to paints having "soluble" metal contents in the range of about 0,05 to 5 % (m/m). The flame atomic absorption spectroscopic method (AAS) (clause 3) should be used as the reference method. Other methods can be used by agreement between the interested parties. A polarographic method is given in clause 4. In case of dispute, the AAS method should be used.

DS/ISO 3856/5:1982 色漆和清漆.“可溶性”金属含量的测定.第5部分:液体色漆或粉状色漆的颜料中六价铬含量的测定.二苯卡巴肼分光光度法

This part of ISO 3856 specifies a diphenylcarbazide spectrophotometric method for the determination of the "soluble" hexavalent chromium content of the hydrochloric acid extract of the pigment and extender portion of the product, prepared according to clause 7 of ISO 6713 or other suitable Interna-tional Standards.1) The method is applicable to paints having "soluble" metal contents in the range of about 0,05 to 5 % (m/m). Other methods can be used by agreement between the interested parties, provided that the methods are specific for hexavalent chromium but, in case of dispute, this spectrophotometric method should be used.

DS/ISO 3856/6:1982 色漆和清漆.“可溶性”金属含量的测定.第6部分:色漆液体中铬总含量的测定.火焰原子吸收光谱测定法

This part of ISO 3856 specifies a flame atomic absorption spectroscopic (AAS) method for the determination of the total chromium content of the liquid portion of the paint, prepared according to clause 8 of ISO 6713 or other suitable International Standards.1) The method is applicable to paints having "soluble" metal contents in the range of about 0,05 to 5 % (m/m). Other methods can be used by agreement between the interested parties but, in case of dispute, this AAS method should be used.

DS/ISO 3905:1982 色漆和清漆.在固定涂覆速率下浅色色漆对比率 (不透明性) 的测定(用黑白图)

This International Standard specifies a method to be used for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of reflectance value greater than 25 %, applied at a spreading rate of 20 m2/l to an agreed black and white substrate.

DS/ISO 3906:1982 色漆和清漆.在固定涂覆扩展速率下浅色色漆对比率 (不透明性) 的测定 (用聚酯薄膜)

This International Standard specifies a method to be used for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of reflectance value greater than 25 %, applied at a spreading rate of 20 m2/l to col-ourless transparent polyester film, the reflectance being measured subsequently over agreed black and white glass piates.

DS/ISO 6270:1982 色漆和清漆.耐湿度(连续冷凝作用)性的测定

1 This International Standard specifies a method for deter-mining the resistance of paint films, paints systems and allied products to conditions of high humidity. 2 The method is applicable to coatings both on porous substrates such as wood, plaster and plasterboard, and on non-porous substrates such as metal. It provides an indication of performance likely to be obtained under severe conditions of exposure where continuous condensation occurs on the surface. 3 The procedure may reveal failures of the coating (including blistering, staining, softening, wrinkling and embrittle-ment) and deterroratton of the substrate.
