Trade specifications

Trade specifications for the chlorobenzenes are subject to modification by agreement with the customer of each producer s standards. AH of the chlorobenzenes show readily separated and identifiable peaks by glc. This method is used exclusively for plant, quaUty control, and for sales specifications. 

Having examined the results achieved during Operation Crystal Flow, the Board notes that increased monitoring of ephedrine and pseudoephedrine caused traffickers to obtain non-scheduled substances. Some of the non-scheduled substances were traded specifically to circumvent controls. The Board therefore urges competent authorities to establish adequate mechanisms for identifying suspicious transactions involving non-scheduled chemical substances.

Currently, PV generally is not included in industry product definitions or trading specifications, but increasingly appears in buyer purchase specifications. Oils with wide ranges of PV values have been reported fed to different species with varying toxic effects. The AOCS will table the AOM method as means for predicting the... 

Polysulphide sealants were used in building structures for a long time before a standard specification was developed for such uses. ASA-A116.1 was the first specification for building sealants written by the Building Trade Specification Committee in 1956. Later, several specifications were designated by different societies for one-component and two-component systems. The specifications will be mentioned in the following. Apart from polysul-phides these specifications also refer to urethane and silicone sealants...

The major characteristics usually included in national and international standards and trading specifications and used for quality control in laboratories are as follows. 

The Codex draft standard (Table 6.8) specifies the IV range of CNO as 6.3-10.6, while both the Malaysian Standard (Table 6.7) and the MEOMA trading specification give 7.5-10.5, a considerably narrower range. Oil of lower IV comes from kernel meat which has had the testa (the thin brown layer between kernel and shell) pared off, as in the production of desiccated coconut. This parings oil has an IV of about 48-50 (Hui 1996, p. 100). 

The specifications and test values of oils given in various surveys and in the national and international standards (such as Codex), provide a useful insight into their properties and can be used as guides for good quality. However, they are intended to be advisory only and are not implied in any contract, unless they are specifically included. Commercial contracts are normally based on trade specifications which give rounded values for a few basic characteristics. The specifications of the Malaysian Edible Oil Manufacturers Association (MEOMA 2001) for crude and refined CNO are shown in Table 6.11 and those of a major EU refiner for both refined and hydrogenated CNO are shown in Table 6.12. 

Trade specifications show what is possible on the industrial scale. A very common mistake made by end-users is to ask for some small change or a narrower range in a particular property of commodity oils. This is nearly always... 

Under this heading are included the characteristics usually specified in national and international standards and trading specifications. These are the values most often used in the quality control laboratories of oil processors and users. For a general discussion of IV, mp and SFC, see also under CNO (Sections 6.22.2 to 6.2.2.4). 

The MEOMA trading specification for PKOs and PKOo are shown together those of PKO in Table 6.24. 

The National Collective agreement that is ne tiat and signed every year by the Panellenic Union of Lithogrqjhers, Gr hic Arts, Press and AUi Trades specifically mentions the Employer s duty to comply with the provision of ... 

Our results on the wettability of surfaces covered with highly fluorine-substituted alkyl groups stimulated several research laboratories to apply these surface properties to polymeric coating materials for textile fibers and fabrics as a means of imparting to them nonstaining, oil-, and water-resistant properties. Such products are becoming very prominent today and the contact angle is used for product control and trade specifications [1]. 

Trading specifications for crude oils have been discussed by Pritchard (1983). Contracts, trading rules and specifications are issued by a number of national and international organizations amongst which are FOSFA (Federation of Oils, Seeds and Fats...

Unfortunately, the monitored m/z in the SIM technique could represent the combination of isobaric/isomeric species leaving us without unique identifiers. This is typical for the SIM analysis of a very complicated sample such as a serum or plasma sample where many compounds have the same m/z including multiply charged m/z of the species or stable isotopologues. Therefore, the technique is a kind of trading specificity for sensitivity. This technique is seldom used in modem lipidomics analysis due to its limitations. 

As previously mentioned, free fatty acids are precursors for peroxides and carbonyl compounds such as aldehydes and ketones that give rancid smell to the oil. A combination of factors accelerates the spoilage of oil such as the presence of metals, water, and high storage temperatures. The following are typical quality and trading specifications used by the edible oil industry of a final product that will have a good shelf life (29) ...
