There are two types of digital signature mechanism: When the verification process needs the message as part of the input, the mechanism is called "signature mechanism with appendix". A hash-function is in used in the calculation of the appendix. When the verification process reveals all or part of the message, the mechanism is called a "signature mechanism giving message recovery". A hash-function is also used in the generation and verification of these signatures. ISO/IEC 14888 specifies digital signatures with appendix. ISO/IEC 14888-1:2008 specifies general principles and requirements for digital signatures with appendix. ISO/IEC 14888-2 addresses digital signatures based on integer factoring, and ISO/IEC 14888-3 addresses digital signatures based on discrete logarithm. Signature mechanisms giving message recovery are specified in ISO/IEC 9796. Hash-functions are specified in ISO/IEC 10118.

This part of ISO/IEC 14888 specifies digital signatures with appendix whose security is based on the difficulty of factoring the modulus in use. For each signature scheme, it specifies: a) the relationships and constraints between all the data elements required for signing and verifying; b) a signature mechanism, i.e., how to produce a signature of a message with the data elements required for signing; c) a verification mechanism, i.e., how to verify a signature of a message with the data elements required for verifying. The production of key pairs requires random bits and prime numbers. The production of signatures often requires random bits. Techniques for producing random bits and prime numbers are outside the scope of this part of ISO/IEC 14888. For further information, see ISO/IEC 18031 [33] and ISO/IEC 18032 [34]. Various means are available to obtain a reliable copy of the public verification key, e.g., a public key certificate. Techniques for managing keys and certificates are outside the scope of this part of ISO/IEC 14888. For further information, see ISO/IEC 9594-8 [27], ISO/IEC 11770 [31] and ISO/IEC 15945 [32].

IEC 60335-2-25:2010+A1:2014+A2:2015 deals with the safety of microwave ovens for household and similar use, their rated voltage being not more than 250 V. This standard also deals with combination microwave ovens, for which Annex AA is applicable. This standard also deals with microwave ovens intended to be used on board ships, for which Annex BB is applicable. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. However, if the appliance is intended to be used professionally to process food for commercial purposes, the appliance is not considered to be for household and similar use only. The principal changes with respect to the previous edition are as follows: - the scope is modified to, cover microwave ovens on board ships, to better define seperation between "household and similar use" and "commercial use" and indicate it does not to take into account persons whose capabilities or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction and children playing with the appliance; - the intended use is defined for clarification; - the door endurance test is rationalised; - the replacement of 22.103, 22.104 and 22.105 allows interlock systems with at least one concealed door interlock as well as alternative interlock systems without concealed door interlock; - the tests on electronic door interlock systems are defined for clarification; - the pollution degree of combination microwave ovens is defined for clarification; - the thickness requirement for sheaths of visibly glowing heating elements of combination microwave ovens is defined for clarification. It is the recommendation that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. This consolidated version consists of the sixth edition (2010), its amendment 1 (2014) and its amendment 2 (2015). Therefore, no need to order amendments in addition to this publication.

This international Standard specifies a method for the determination of the chemical oxygen demand, COD, of water. It is applicable to water with a COD value of between 30 mg/l and 700 mg/l. The chloride content must not exceed 1000 mg/l. A water sample which is in accordance with these conditions is used directly for analysis. If the COD value exceeds 700 mg/l, the water sample is diluted. For greatest accuracy it is preferable that the COD value of the sample is in the range of 300 mg/l to 600 mg/l. Under the given reaction conditions, organic compounds are extensively oxidized. Excluded are compounds with certain structural elements (e.g. pyridine nucleus, quaternary nitrogen compounds). Volatile hydrophobic substances may evaporate and thus escape the oxidation. Inorganic compounds being oxidized under the reaction conditions are, for example: — bromide ions, iodide ions; — certain sulfur compounds; — nitrite ions; and — certain metal compounds. On the other hand, certain compounds may react as oxidizing agents under the reaction conditions. Depending on the use of the test results, these circumstances shall be kept in mind. For interferences, particularly from chlorides, see clause 10.

This International Standard describes a method for determining certain organochlorine insecticides, polychlorinated biphenyls (PCBs) and chlorobenzenes (except the mono- and dichlorobenzenes) in drinking waters, ground waters, surface waters and waste waters. The method is applicable to samples containing up to 0,05 g/l of suspended solids. In the presence of organic matter, suspended matter and colloids, interferences are more numerous and consequently the detection limits are higher. The method described in this International Standard only gives information on specific PCB compounds but no information on the level of total PCBs. According to the types of compounds to be detected and the source of the water, the detection limits given in table 1 are applicable for the method described in this International Standard, with waters of low organic contents. Given the very low concentrations normally present in the waters, the problem of contamination is extremely important. The lower the level measured, the more precautions have to be observed; below concentrations of 10 ng/l, special care is necessary.

This part of ISO 6703 specifies three methods for the determination of total cyanide (see clause 2) in water. The methods are applicable to water containing less than 100 mg of cyanide per litre, but higher concentrations may be determined by suitable dilution of the sample. The methods and corresponding ranges of cyanide contents for which they are suitable are as follows: — Photometric method with pyridine/barbituric acid : 0,002 to 0,025 mg ; — Titrimetric method using the Tyndall effect: > 0,005 mg; — Titrimetric method using an indicator: > 0,05 mg. A large number of ions and compounds interfere with the determination. These are listed in the table 1, together with the concentrations below which they do not interfere (the list is not exhaustive). If present singly or in combination, up to the limiting concentrations, they do not interfere with the separation of hydrogen cyanide. The presence of aldehydes, e.g. formaldehyde, causes low cyanide values because of the formation of cyanohydrin. If any of the limiting concentrations of the interferences is likely to be exceeded, the sample shall be diluted with distilled water before stabilization (see clause 6). Other interference may arise from the presence of fatty acids, which will distil and form soaps during titration of alkaline solution, and from the presence of elementary sulfur.

Table 1 — Interferences Interference Limiting concentration, mg/l Sulfide ions 1 000 Polysulfide ions 500 Sulfide and polysulfide ions 1 000 Sulfide ions 500 Thiosulfate ions 1 000 Thiocyanate ions 1 000 Carbonate ions 1 000 Cyanate ions 1 000 Nitrate ions 500 Nitrite ions 500 Ammonium ions 2 000 Iron(II) and iron(III) ions 5 000 Copper(II) ions 100 Nickel(II) ions 50 Silver ions 50 Mercury ions 50 Chromate ions 300 Propionic acid 1 000 Phenol 1 000 Anthracene 100 Naphthalene 100 Anisaldehyde 10 Piperonal 10 Pyrrole 100 Pyridine 10 Chlorine (elemental) 250 Hydrogen peroxide 10 Perborate ions 10 If any of the limiting concentrations of the influences are likely to be exceeded, dilute the sample with distilled water before stabilization (see clause 6). Prussiates (pentacyano complexes with iron), which cannot be destroyed by chlorination under normal conditions of waste water treatment, partly decompose (up to 50 %), releasing hydrocyanic acid under the conditions specified. If it is desired to exclude prussiates, the procedure specified in clause 6 and 7.1 has to be used. This procedure is only applicable, however, if the concentration of copper ions in the sample is less than 1 mg/l. The presence of aldehydes, e.g. formaldehyde, may give lower cyanide values because of the formation of cyanohydrin.
