Manufacturing

This part of PD 8010 provides all those with an involvement in pipeline systems – designers, equipment manufacturers, fabricators, constructors, installers, executive operators, site operators, control room operators, integrity and maintenance engineers, safety and associated pipeline personnel – with guidance on how to ensure that any pipeline system retains its integrity: i.e. that it continues to function as originally intended for the duration of the required operating life, which might be significantly longer than the original design life.

This draft standard describes a method for the determination of the preservative 3‑iodo‑2‑propynyl butylcarbamate (IPBC) - regulated in the Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products, Annex V No. 56 - in cosmetic preparations in the concentration range from 0,005 g/100 g to 0,1 g/100 g.

This draft standard describes a multi-screening method using reversed-phase HPLC for the detection of UV filters listed in Annex VI of the Regulation (EC) No 1223/2009. The method is applicable for the quantitative determination of 10 UV filters which are mainly used in emulsion-based sun screen products and sun screen sprays particularly with regard to the maximum concentration listed in Annex VI.

Other analytical methods for the qualification and quantification of UV filters may be used if they lead to comparable results.

This draft standard describes an analytical method for the detection and quantitative determination of the following anti-dandruff agents: Zinc pyrithione, piroctone olamine and climbazole in surfactant-containing cosmetic products in the concentration range from 0,1 g/100 g to 1,0 g/100 g.

NOTE          The method is also suitable for the determination of ketoconazole and ciclopirox olamine (q.v. Annex A) in surfactant-containing cosmetic products and it’s probably applicable for the determination of the substances in non surfactant-containing cosmetic products. For these purposes the method has not been validated.

This European Standard specifies the technical delivery conditions for semi-finished products, hot or cold formed bars, rods, wire, sections and bright products of standard grades and special grades of corrosion resisting stainless steels for general purposes.

NOTE          General purposes include the use of stainless steels in contact with foodstuffs.

The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.

This European Standard does not apply to components manufactured by further processing of the product forms listed above with quality characteristics altered as a result of such further processing.

This European Standard specifies the technical delivery conditions for hot or cold rolled sheet/plate and strip of standard grades and special grades of corrosion resisting stainless steels for general purposes.

NOTE          General purposes include the use of stainless steels in contact with foodstuffs.

The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.

This European Standard does not apply to components manufactured by further processing of the product forms listed above with quality characteristics altered as a result of such further processing.

—       method A, using a flexural stress of 1,80 MPa;

—       method B, using a flexural stress of 0,45 MPa;

—       method C, using a flexural stress of 8,00 MPa.

The standard deflection Δs used to determine the temperature of deflection under load corresponds to a flexural-strain increase Δεf defined in this part of ISO 75. The initial flexural strain due to the loading of the specimen at room temperature is neither specified nor measured in this part of ISO 75. The ratio of this flexural-strain difference to the initial flexural strain depends on the modulus of elasticity, at room temperature, of the material under test. This method is therefore only suitable for comparing the temperatures of deflection of materials with similar room-temperature elastic properties.

NOTE          The methods give better reproducibility with amorphous plastics than with semi-crystalline ones. With some materials, it may be necessary to anneal the test specimens to obtain reliable results. Annealing procedures, if used, generally result in an increase in the temperature of deflection under load (see 6.6).
