Commercial Evaluation Category

Commercial evaluation permit This is a permit which can be obtained for a maximum of 2 years and for a maximum of 4000 kg of the chemical or polymer. This permit is usually obtained as a precursor to one of the main notification categories above. The intention is to evaluate the market feasibility of the chemical before committing to a full notification. Chemicals which are used in consumer end-use products do not qualify for this permit 14... 

A great number of measurements have been reported for articles electroplated with zinc. The various aims have been evaluation of the corrosion rate of zinc that had been plated in a number of commercial cyanide-free zinc baths," comparison of the corrosion rate of a composite material (zinc with codeposits of various oxides) and of pure zinc deposits," corrosion testing of various alloyed zinc platings (Zn-Ni, Zn-Co, Zn-Fe), with or without subsequent post-treatment. Most of the work in the last category was only recorded in internal reports. The published work consists of an examination of the corrosion behavior of a ctoomated Zn-Fe... 

The point score for the evaluation of flowability of dry solids is given in Table 1. In order to measure the flowability of a powder utilizing this method, each test is made and the points can be found in the table. The total number of points would place the sample into one of the seven categories in the left column of the table. Because of its simplicity and the fact that commercial devices are available to conduct these tests (this test is ASTM test designation D 6393-99), this system is widely used in the pharmaceutical industry... 

The sources of informafion used to evaluate burner performance on commercial scale insfallafions fypically falls into one of three categories (i) combustion performance in the oxy-fuel fired zone, (ii) flue gas emissions from the furnace (including any parficulafe maffer), and... 

In this section, some of the operational experiences and recent developments for explosives detection are discussed. Most of the data in this section were published by law enforcement agencies or supplied by manufacturers of commercial IMS devices. Thus, there is an emphasis on practical aspects and field tests. The descriptions are based mainly on the manufacturers claims and brochures, except if objective reports on comparative evaluations and field tests were available. The common or conventional explosives that contain nitro functional groups can be divided into two categories relatively volatile substances such as NG and EGDN and low-vapor-pressure materials such as RDX, PETN, and HMX. The vapor pressure of TNT is between these two groups. There are several commercial and military composites that are mixtures... 

PVAc-based commercial wood adhesives are evaluated using standard tests for non-structural applications, as reported in EN 205 [8], and they are classified in agreement with the standard EN-204 [9]. This standard allows to classify wood adhesives in 4 categories from D1 to D4. D1 adhesives show a good resistance only in dry conditions D2 adhesives should withstand a rather low water presence, such as in occasional exposure in kitchens and bathrooms D3 adhesives are suitable to come in contact with cold water, such as for outside windows and doors, kitchen and bathrooms furniture D4 adhesives are suitable to be used in extreme conditions (resistance to hot water). Vinyl acetate homopolymer can be used to formulate D1 or D2 adhesives. Vinyl acetate based adhesives cross-Unked with hardeners and urea-formaldehyde (UF) adhesives belong to class D3. Only the phenol-formaldehyde (PE), resorcinol-formaldehyde (RF) and melamine-formaldehyde (MF) adhesives, some special 2-component polyurethanes (PUs), and cross-linking vinyl adhesives belong to class D4.
