BS 8529:2010 pdf download – Composite doorsets – Domestic external doorsets – Specification
5.3 Glazing gaskets and weatherseals Glazing gaskets and weatherseals shall conform to British Plastics Federation publication 345/2.
5.4 Glass Glass thickness and type shall be selected using the recommendations given in BS 6262‑1, BS 6262‑2, BS 6262‑3, BS 6262‑4 and/or BS 6262‑7, as appropriate. If BS 6262‑3 is used to select the glass, the wind load shall be calculated in accordance with BS 6375‑1 or BS 6399‑2. Insulating glass units shall conform to BS EN 1279.
5.5 Hardware except for fixings Materials for all hardware, except for fixings as defined in 3.8, shall have at least the equivalent corrosion resistance of BS EN 1670:2007, grade (class) 3 (96 h) when subjected to a neutral salt spray test as specified in BS EN ISO 9227. Tests shall be carried out on complete hardware items as supplied. NOTE 1 There is no direct correlation between a given number ofhours salt spray testing and real‑time natural environment exposure.
NOTE 2 In certain coastal or industrial environments, austenitic stainless steel hardware conforming to BS EN 10088‑2 is particularlysuitable.
5.6 Fixings for hardware Fixings for hardware shall conform to GGF data sheets
6.7 and 6.8. Fixings for plastics shall additionally conform to British Plastics Federation publication 363/1.
6 Construction and design
6.1 Manufacturing tolerances When measured in accordance with BS EN 951, the overall height and width of the door leaf shall be within ±3 mm of the work size (3.13).
The difference between the diagonals of the assembled frame shall be not more than 4 mm. For door leaves that have identical moulding details on both faces, the mouldings shall be aligned both horizontally and vertically between the external and the internal face. When measured in accordance with BS EN 951, the reference points of opposing mouldings shall align between the two faces with a difference of not more than 6 mm.
6.2 Door leaves The door leaves however designed shall move freely and smoothly without hindrance throughout their intended range of movement.
6.3 Design for glazing The frame design shall be such that:
a) the door leaf can be glazed in accordance with BS 6262;
b) reglazing is possible without the need to remove the outer frame from the structure of the building;
c) it is possible to renew the weatherseals without removing the outer frame from the structure of the building; d) it is possible to replace the hardware without removing the outer frame from the structure of the building.
6.4 Ventilation devices Ventilation devices shall not permit the penetration of moisture into any profile chambers that are not designed to have moisture in them. NOTE Conformityto this requirementis determined byvisual examination.
7 Appearance and finish
7.1 General NOTE Composite doorsets can be supplied with a varietyoffinishes, including painted finishes and finishes integral to the facing material. Doorsets can be supplied fully finished, unfinished for site painting, or a combination as agreed between the contracting parties. The colour and/or appearance of an assembled door, whether supplied fully finished or for finishing on site, shall be uniform and consistent when viewed by normal or corrected vision at a range of 1 m, facing 45° north‑sky light in natural light, viewing perpendicular to the surface in accordance with BS EN ISO 105‑A01:1996, Clause 14.
7.2 Doorsets supplied fully finished
NOTE 1 A feature ofsome composite doorsets is the presence ofa simulated woodgrain textured surface. This makes measurement ofcolour and gloss by absolute methods impossible. Where control ofthis feature is part ofthe specification, it can be achieved only by using agreed variation samples and discussion with the customer. For fibre‑reinforced thermoset (FRT) surfaces, there shall be no break‑out of the fibre more than 6 mm away from a fabricated area or cut edge.
NOTE 2 Particular care is required with double doors, and the finish for both leaves should come from the same batch where possible. For doors with a gloss finish, the variation in gloss value, when determined in accordance with BS EN ISO 2813, shall not exceed 20 gloss units within a door, or 15 gloss units between a door and its agreed comparison sample or declared gloss value.
