STANAG 2835

STANAG 2835 ultraviolet-reflecting white camouflage colour

Makers of camouflage paints, coatings, tarpaulins, nets, covers and other materials used to camouflage military equipment in snow, and the defence buyers who specify them.

STANAG 2835 sets the optical properties NATO requires of the ultraviolet-reflecting white colour used to camouflage military equipment in snow. NATO has not released it publicly; this page describes it from the Czech defence standard that implements it.

NATO has not released this STANAG publicly. It is NATO UNCLASSIFIED, and organisations that need it obtain it through their national standardization authority.

What it is

STANAG 2835 is the NATO Standardization Agreement on ultraviolet reflecting (UVR) white colour for the camouflage of military equipment in snow environments. Edition 2, promulgated in September 1995 under NATO's land armaments committee (CNAD, AC/225 NAAG, MILENG, MatP), it sets the optical properties this white colour must have so that objects painted or covered with it are harder to detect on snow-covered terrain.

NATO has not released STANAG 2835 publicly. This page describes it from a public national implementation, the Czech defence standard ČOS 108007 (3rd edition, amendment 2, 2025), which states that it introduces STANAG 2835 edition 2 into Czech use. A national implementation can add national requirements and reservations, so treat what follows as the Czech implementation's content, not as NATO's own text.

What the Czech implementation requires of the colour

ČOS 108007 defines the properties of NATO UVR white colour, which reflects part of the ultraviolet spectrum as well as visible light, so that a coated object is harder to detect across a spectral band running from near-ultraviolet to near-infrared on snow-covered ground. It may be applied as a removable or permanent camouflage coating on military equipment and gear, on protective-layer fabrics such as waterproof tarpaulins, on camouflage covers or mats, on other fabrics, and on other materials and products that need camouflage.

The colour's technical conditions are set by three optical characteristics, and it must not be fluorescent. Across the range 320 nm to 1200 nm, the spectral reflectance curve of the coated surface must fall within a tolerance band between an upper and a lower limit curve. Its colorimetric characteristics are fixed chromaticity coordinates measured against two standard illuminants (D65 under a 10-degree observer, and illuminant C under a 2-degree observer), each giving a luminance factor of 87.4 percent and a CIELAB lightness of 94.9; the maximum acceptable colour difference is 4 CIELAB units, tightened to a recommended 2 units where several nations' suppliers need to agree a stricter match under a bilateral or multilateral programme. Specular gloss, measured before any correction for diffuse light, must not exceed a gloss value of 8 at a 60-degree viewing angle for painted surfaces, coated fabrics, and camouflage covers or mats; other products set their own gloss value.

The Czech implementation adds narrower national figures on top: for the Czech armed forces the maximum colour difference is tightened to 3 CIELAB units, and the maximum gloss value is capped at 3 at 60 degrees for painted, coated and covered items, at 8 at 85 degrees for other products, or set by the Czech camouflage-pattern standard for uniforms and other patterned kit.

How conformity is checked

ČOS 108007 sets out the measurement methods behind those figures. Spectral reflectance and the colorimetric values are both checked with a spectrophotometer fitted with an integrating sphere, against a barium sulphate or calibrated white reference standard; reflectance is measured across 320 nm to 1200 nm and colorimetric values across 380 nm to 780 nm in 10 nm steps, under illuminant D65 or C and the corresponding CIE observer. Specular gloss is checked with a gloss meter at a 60-degree viewing angle against a black glass or calibrated black reference standard, corrected for any diffuse light contribution where that correction has been agreed.

Put STANAG 2835 on a system that keeps the evidence

Documents, training, risks and evidence in one place, with the trail an auditor asks for.

How we help

A supplier bound by STANAG 2835 through a contract holds the obtained text through its national authority. In ComplyTrain you record the requirements that apply to you as your own requirements, give each an owner, and keep the evidence that shows you meet them against each one.

    AI reads the tender pack and pulls out the requirements, deadlines and rules - then helps you draft the response from your own approved content, with you reviewing every step.

  • Stakeholder/Vendor Management

    One current register of the suppliers and partners you depend on - each risk-assessed, re-assessing itself on schedule, and wired straight into your risk register.

  • Requirements Management

    See every requirement you face - across every standard, plus your own contracts and policies - traced to the documents, evidence and processes that satisfy it.

  • Risk Management

    Identify, score, treat and review your risks in one place - with AI to help anyone run a proper assessment, and a defensible trail behind every decision.

  • Training Management

    Assign training, prove it was understood, and hold the competence records an auditor asks for.
