ISO 15015 pdf download Plastics — Extruded sheets of impact- modified acrylonitrile-styrene copolymers (ABS, AEPDS and ASA) — Requirements and test methods
1 Scope
This International Standard specifies the requirements and test methods for solid flat extruded sheets ofimpact-modified acrylonitrile-styrene copolymer materials: acrylonitrile-butadiene-styrene (ABS), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS)(commonly known as AES) and acrylonitrile-styrene-acrylate(ASA), without fillers or reinforcing materials. This International Standard also applies to ABS,AEPDS andASA sheet in rolled form. It applies only to thicknesses from 0,25 mm to 20,0 mm.

Material
Sheets shall be made of either ABS extrusion materials as defined in ISO 2580-1 or AEPDS (AES) or ASAextrusion materials as defined in ISO 6402-1, without fillers or reinforcing materials. The extrusion materialscan contain additives such as processing aids, stabilizers, flame-protective agents and colorants. Compoundsand additives of unknown identity shall not be used.
NOTE Legal conditions might necessitate a specific choice of extrusion material (see 4.3.3).
4 Requirements
4.1Appearance
Sheets shall be substantially free from bubbles, voids,cracks, visible impurities and other defects which wouldmake them unfit for the intended use.Surfaces shall be substantially smooth, if not embossed, and free fromgrooves, sink marks or damage. Colorants shall be homogeneously distributed throughout the material.Slightcolour variations due to variations in the extrusion compound or processing conditions are admissible. Theexact extent of variations in any of the above, as well as gloss level specifications, if required, shall be agreedbetween the interested parties.Sheets shall be examined in accordance with 5.3.
4.2Dimensional tolerances
4.2.1 Thickness
Within any delivery of sheets, the maximum thickness variation from the nominal value，,h， in milimetres,shall satisfy the requirement
l Ahl ≤(0,03 mm + 0,04 × hn)
(1)
where h, is the nominal sheet thickness, in millimetres.
Within any individual sheet,the maximum thickness variation, Ahp, in millimetres, shall satisfy the requirement
l Ah2l ≤(0,03 mm + 0,02× hn)
(2)
Testing shall be in accordance with 5.4.1.
4.2.2Length and width
The nominal length, 1. , and nominal width, b,, of sheets shall be as agreed between the interested parties.Unless agreed differently, the length shall be in the direction of extrusion.
For any individual sheet selected at random from any delivery, the tolerances on length and width shall be inaccordance with Table 1.Testing shall be in accordance with 5.4.2.
