SIST EN 14315-1:2013 PDF

Overview - SIST EN 14315-1:2013 (in-situ sprayed PUR/PIR)

SIST EN 14315-1:2013 is the European specification for in‑situ formed sprayed rigid polyurethane (PUR) and polyisocyanurate (PIR) foam spray systems before installation. This Part 1 document defines the product characteristics of the spray system (raw components and system as supplied), and specifies procedures for testing, marking and labelling, and evaluation of conformity. It is the harmonised, pre‑installation complement to Part 2 (installed product specification). The standard applies to spray foam used on walls, ceilings, roofs, suspended ceilings and floors, and explicitly excludes factory‑made boards and products intended for building equipment or industrial installations.

Key topics and technical requirements

The standard addresses product-level requirements and the supporting test and conformity framework, including:

• Product definition and scope - coverage of rigid PUR and PIR spray foams (including “semi‑rigid” or low‑density variants) and exclusions.
• Performance characteristics - documented product properties relevant to thermal insulation (e.g., declared and aged thermal conductivity/thermal resistance), density, dimensional stability and compression behaviour.
• Testing procedures - methods and sample preparation for determining key properties (see normative annexes for procedures such as determination of aged thermal conductivity, free‑rise density, substrate adhesion, and reaction to fire).
• Reaction to fire - test arrangements for reaction‑to‑fire assessment, including tests in standardised assemblies simulating end‑use applications.
• Quality control and conformity - requirements for Initial Type Testing (ITT), Factory Production Control (FPC) and rules for CE marking and manufacturer declarations.
• Marking and technical information - labelling requirements and mandatory product information to accompany supply and installation.

Practical applications and users

This standard is essential for stakeholders involved with spray polyurethane/polyisocyanurate insulation systems:

• Manufacturers and formulators of spray foam systems preparing product datasheets and CE marking documentation.
• Test laboratories and certification bodies conducting ITT, FPC and reaction‑to‑fire evaluations.
• Architects, specifiers and consultants selecting spray foam systems for building thermal envelopes.
• Contractors and installers who need to understand system properties before application.
• Regulators and compliance officers assessing fitness for purpose in line with national regulations and non‑conflicting standards.

Related standards (normative references)

SIST EN 14315-1:2013 references multiple EN test standards commonly used for thermal insulation, for example:

• EN 1602 (apparent density), EN 823 (thickness), EN 826 (compression behaviour)
• EN 1604 (dimensional stability), EN 1605 (deformation under load), EN 1606 (compressive creep)
• EN 1607 (tensile strength perpendicular to faces), EN 1609 (water absorption)

Using SIST EN 14315-1:2013 helps ensure consistent, verifiable product data for in‑situ sprayed rigid PUR/PIR insulation systems and supports compliance, quality control and safe specification in building projects.
