  1. dimensions and tolerances (see Clause 7);

  2. physical requirements and characteristics (see Clause 8);

  3. durability (see Clause 9);

  4. release of dangerous substances (see Clause 10);

  5. moisture movement (see Clause 11);

  6. reaction to fire (see Clause 12);

  7. performance in a humid environment (see Clause 13);

  8. verification of quality management system (QMS), factory production control (FPC) and consignment inspection (see Clause 14); and
