DIN 18356:2016-09 7 1 Scope 1.1 This standard deals with the laying of parquet flooring and wood block flooring indoors. 1.2 This standard does not cover the laying of joists or

35、 installation of false floors (see DIN 18334). 1.3 DIN 18299, clauses 1 to 5 shall also apply. In cases where the specifications of DIN 18299 contradict the present standard, DIN 18356 shall take precedence. 2 Materials and components The specifications of DIN 18299, clause 2 shall be supplemented a

36、s follows: The DIN Standards and other requirements given below cover the most commonly used materials and components. 2.1 Parquet and wood block flooring DIN 68702 DIN EN 13226 DIN EN 13227 DIN EN 13228 DIN EN 13488 DIN EN 13489 DIN EN 13629 DIN EN 13990 DIN EN 14342 DIN EN 14761 The moisture conte

37、nt of the parquet and wood blocks, upon delivery on site, shall be as specified in the above standards. 2.2 Wood skirtings and cover strips The quality requirements specified in parquet flooring standards shall apply by analogy to wood skirtings and cover strips. 2.3 Nails DIN EN 10230-1 2.4 Adhesiv

38、es 2.4.1 General Adhesives shall provide a strong and permanent bond. They shall not unduly affect the parquet or wood block flooring, underlay or sub-base, or cause an unpleasant smell after application. DIN 18356:2016-09 8 2.4.2 Adhesives for parquet DIN EN 14293 2.4.3 Adhesives for wood block flo

39、oring DIN 68702 2.5 Flooring finishes Flooring finishes shall be such that, in combination with the appropriate care, they protect the surface of the parquet or wood block flooring against the temporary ingress of dirt and fluids. 3 Execution of work The specifications of DIN 18299, clause 3 shall b

40、e supplemented as follows: 3.1 General 3.1.1 Reservations according to VOB/B (DIN 1961), 4, clause 3 could involve in particular the following: any level of the sub-base which is not compatible with that of adjacent building elements, any surface irregularities in the sub-base exceeding the toleranc

41、es specified in DIN 18202, cracks in the sub-base; the surface of the sub-base, if this is soiled, too weak, too porous or too rough, any missing stop beads, sills, etc. up to or against which the flooring is to be laid, the absence of protruding flanking strip at edges, the surface of the sub-base

42、if this is not sufficiently dry to be covered, in floors with underfloor heating, any missing marking of measuring points, any unsuitable temperature of the sub-base, unsuitable conditions as a consequence of the weather conditions or indoor climate. 3.1.2 If conditions are unsuitable due to the wea

43、ther or the indoor climate (e.g. component temperatures below 15 C for laying work), special precautions shall be taken, in consultation with the client. If work is necessary as a result, this shall count as a special task (see subclause 4.2.16). 3.1.3 Deviations from the dimensions specified are pe

44、rmitted subject to their compliance with the tolerances specified in DIN 18202. Surface irregularities, visible in glancing light, are permitted subject to their compliance with the tolerances specified in DIN 18202. If surfaces are required to conform to requirements regarding flatness more stringe

45、nt than specified in DIN 18356:2016-09 9 DIN 18202:2013-04, Table 3, line 4 or to other requirements regarding dimensional accuracy specified in the same standard, the necessary work counts as a special task (see subclause 4.2.1). 3.1.4 Parquet or wood block flooring shall only be laid on a sub-base

46、 that is sufficiently dry. In order to avoid damage to the underfloor heating systems, the moisture content shall only be measured at the appropriately marked points. 3.1.5 The contractor shall provide the client with care instruction documents. These shall also contain information regarding the sui

47、table indoor climate. 3.2 Laying of parquet flooring 3.2.1 General 3.2.1.1 Parquet flooring shall be made from elements of class O. Solid softwood floor boards shall be class A.
