The work of preparing Inte

25、rnational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison wi

26、th ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as a

27、n International Standard requires approval by at least75% of the member bodies casting a vote.

Descriptors: Paints, varnishes, substrates, steel products, blast-cleaning, abrasives, non-metallic abrasives, specifications, generalities.BSENISO11126-1:1997 BSI 02-1999 1 Introduction This is one of a number of parts of ISO11126 speci

31、fying requirements for non-metallic abrasives for blast-cleaning. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO11127 (seeAnnex A). The requirements for metallic abrasives commonly used for blast-cleaning are specified in the various parts of ISO11124. T

32、est methods to be used to define these requirements are contained in the various parts of ISO11125 (seeAnnex A). Abrasive blast-cleaning techniques are widely used to clean and prepare surfaces. During work on development of a series of International Standards dealing with the preparation of steel s

33、ubstrates before application of paints and related products, it was decided that a need existed for a series of International Standards covering those blast-cleaning abrasives commonly used in preparation of steelwork. The type of blast-cleaning abrasive used and its particle shape can significantly

34、 affect the surface appearance and profile form of the treated surface. The informative supplement to ISO8501-1 1)provides photographic examples of the change in appearance imparted to steel when blast-cleaned with different abrasive types. ISO 8503-2 2)describes the assessment of the surface roughn

35、ess of prepared surfaces using comparators. Table 1 of this part of ISO11126 identifies the type of comparator to be used with each of the blast-cleaning abrasives considered. WARNING Equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. Many national r

36、egulations exist for those materials and abrasives that are considered to be hazardous during or after use (waste management), such as free silica or carcinogenic or toxic substances. These regulations are therefore to be observed. It is important to ensure that adequate instructions are given and t

37、hat all required precautions are exercised. 1 Scope This part of ISO11126 describes a classification of non-metalllic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the comple

38、te designation of such abrasives. This part of ISO11126 applies to abrasives supplied in the “new” or unused condition only. It does not apply to abrasives either during or after use. NOTE 1Although this part of ISO11126 has been developed specifically to meet requirements for preparation of steelwo

39、rk, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described inISO8504-2:1992, Preparation of steel substrates before application of paints and related products Surface prepar

40、ation methods Part2: Abrasive blast-cleaning. 2 Definitions For the purposes of this part of ISO11126, the following definitions apply. 2.1 blast-cleaning abrasive a solid material intended to be used for abrasive blast-cleaning 2.2 abrasive blast-cleaning the impingement of a high-kinetic-energy st

41、ream of blast-cleaning abrasive on to the surface to be prepared 2.3 shot particles that are predominantly round, that have a length of less than twice the maximum particle width and that do not have edges, broken faces or other sharp surface defects 2.4 grit particles that are predominantly angular

45、 blast-cleaning abrasives for steel substratepreparation 3 Classification 3.1 Abrasive type Blast-cleaning abrasives shall be classified according to material, origin or manufacture. Table 1 gives the abbreviated coding which shall be used to identify each of the types considered. NOTE 2The non-meta

46、llic blast-cleaning abrasives listed inTable 1 are those commonly used for the preparation of steel substrates before application of paints and related products. The list is not intended to be exhaustive. 3.2 Initial particle shape The particle shape characterizes the geometric form of the abrasive

47、particles. Basic forms of non-metallic blast-cleaning abrasives are specified in Table 2, together with the symbol which shall be used to describe each. NOTE 3As the particle shape of an abrasive may change during use, only the initial particle shape is given in the various parts of ISO11126. 3.3 Pa

48、rticle size range Non-metallic blast-cleaning abrasives consist of mixtures of differently sized particles. These shall be classified into size ranges. Table 2 Initial particle shape 4 Designation of abrasives Non-metallic abrasives shall be identified by using the full product designation which con

49、sists of the term “Abrasive” followed by “ISO 11126” and the abbreviation specified inTable 1. This shall be followed, without spaces, by an oblique stroke and then by the symbol specified inTable 2 to indicate the required particle shape of the abrasive as purchased. The designation shall be completed by numbers denoting the particle size range, in millimetres, required. EXAMPLE 1 Abrasive ISO11126 N/CS/G 0,2-0,5 denotes an abrasive of the non-metallic coal furnace slag type, comp
