Where conformity assessment involves intervention of third party, that task is normally carried out by the notified body. The pressure equipment directive enables in addition the national authorities to authorise in their territory user inspectorates for the carrying out of conformity assessment procedures which relate to product verification. These inspectorates shall act exclusively on behalf of the group of which they are part. The placing on the market and putting into service of equipment which has undergone such assessment is however limited to the territory of the authorising Member State and to those Member States which have also proceeded to such authorisation. The equipment concerned shall therefore not bear the CE-marking. 

The name, number, and voltage of equipment controHed should be clearly marked on aH switch boxes, compensators, and starters. Pias and chains should be required on aH butterfly switches. Extension cords should be three-wire and limited to 8-m lengths. 

The particle sizes of liquid and solid dispersoids will vary markedly depending upon the source and nature of the operation generating the particular particles. For design of equipment to reduce or eliminate particles from a fluid stream, it is important either to know from... 

Standard colors have been adopted in the industrial world for the identification of physical hazards, marking of safety equipment, and operating modes of typical equipment. These conventions have been incorporated into standards used worldwide for the recognition of such devices and are categorized by the following color coding. 

Orange a. Offshore survival or evacuation craft and personnel floatation devices. b. Identification of the hazardous parts of machines. c. Marking of the guards for the hazardous parts of machine operations. d. Danger signs. e. Relief valve identification or specialized isolation equipment, e. Directional wind socks. 

Green a. Marking of safety equipment (e.g., gas masks, stretchers, etc.). b. Marking of emergency egress and evacuation routes. c. Control panel indication of a "safe" status of a operating mechanism. d. Safety showers and eyewashes. e. Electrical grounding conductors. f. Safe or acceptable condition indicators.

Utilizing Mark III equipment it is also possible to build plants in the range of 10,000,000 to 20,000,000 gallons per day. Because of economies inherent in large scale production, these plants would have capital costs of one half to two thirds those cited for the case of 2,000,000 gallons per day. Total costs would be lowered in proportion, with some savings in membrane replacement costs as well. 

Hon et al. [34] describe a simple piece of equipment for the determination of down to 80 pg/1 of mercury by AAS using a static cold vapour procedure. In this method [35], the sample was digested with the sulfuric acid, a measured portion pipetted into the reduction vessel, and the vessel immediately capped. The reductant, comprising 1% stannous chloride, was introduced. The evolved elemental mercury in the headspace was then introduced into the absorption cell by water displacement. Maximum sensitivity is obtained when the volume of the displaced air is equal to the internal volume of the absorption cell, and the mercury solution is 9 M in sulfuric acid. The peak absorbance at 253.7 nm exhibited a marked decline for hydrochloric acid concentrations above 1.5 M and for nitric acid concentrations above 3 M. The calibration graph obtained for mercury(II) in 9M sulfuric acid is linear from 0 to 17ng/ml, and the sensitivity is 0.08 ng/ml. A windowless absorption cell can also be used with a narrower linear calibration range. 

Standard operating procedures (SOPs) are required for all routine activities that are critical to the successful outcome of the study including quality assurance procedures and inspections. Most of the SOPs for the field activities are written by the field scientists with guidance from the Quality Assurance Section. For the field activities, it is required that at each site there be SOPs for such things as how field plots are established and the plot boundaries marked, the maintenance of sample freezers, how to calibrate and maintain chemical balances and chemical application equipment, and how to obtain test chemicals. If an SOP for a critical item of equipment is not available, the study would be considered to be not in compliance with the principles of the GLP guidelines. The distribution of SOPs is carefully controlled so that when an SOP is changed, all outdated copies can be exchanged for the new version. 

It should be noted that acoustic irradiation is a mechanical energy (no quantum), which is transformed to thermal energy. Contrary to photochemical processes, this energy is not absorbed by molecules. Due to the extensive range of cavitation frequencies, many reactions are not well reproducible. Therefore, each publication related to the use of US generally contains a detailed description of equipment (dimensions, frequency used, intensity of US, etc.) [709]. Sonochemical reactions are usually marked )))), in accordance with internationally accepted usage [708], For successful application of US, the influence of various factors can be summarized as follows [710] ... 

The objective of absorption equipment is to provide intimate contact between the liquid concerned and gas, thus facilitating the absorption process. When a large volume of gas is absorbed per unit volume of liquid, a marked rise in temperature may result and devices for the removal of the heat evolved are then an important feature of the equipment. Apart from packed towers, the types of equipment described here include agitated vessels, bubble-plate towers, cooler-absorbers and spray towers. 

Hydrogen for commercial use is compressed to 150 atm and distributed in steel cylinders marked red, equipped with left threaded armatures. Electrolytic hydrogen contains 1 to 2% oxygen, which can easily be removed by leading it through platinized asbestos at a temperature of 400 to 500 °C. 

New regulations can markedly change equipment requirements and practices of an industry. While regulators, lobbyists and lawyers negotiated the new law, the fats and oils industry had to start preparing for new market requirements, and food formulators had to develop new products. Likely, the first consideration was selection of ingredients that make Nutrition Facts panels look attractive compared to competitor s products, and which also have functional properties necessary for... 

Special requirements for construction, test and marking of electrical apparatus of equipment group II, category 1 G. 

The marking of Ml equipment goes along with the principles laid down in Chapter 5, with the special marking in the case of using two independent types of protection. The outer protection is indicated first, followed by the internal protection, e.g. ... 

Harmonized European Norms (HN). Group I equipment shall be additionally marked with an Tin a circle according to Directive 82/130/EEC. (b) Marking of Group I equipment in case of a control certificate according to Directive 82/130/EEC. For Group II equipment with a control certificate , the I in the circle shall be deleted. 

The marking of such s -apparatus has been (Sch)s for mining equipment and (Ex)s G... for explosion protected apparatus (suitable for zone 1 applications). In many cases, protection techniques, which are covered by their own standards today, e.g. encapsulation - m - or static pressurization (as a part of pressurization - p - ), have entered the field of explosion protection as s -apparatus [17]. 

Equipment for Volume Studies.— The volume of the specimens may be defcermined by means of several methods of which one or the other may be the more convenient. The direct determination of volume is made most conveniently by means of a voluminometer of the Seger type, illustrated in Fig. 4. The apparatus is first filled with kerosene to the zero mark of the burette which coincides with the zero mark of the tube, attached to the cap of the bottle.
